					                            History Of The
              Power System Dynamic Performance Committee
                              1967 – 2007
                         By P. M Anderson and R. G. Farmer

This document provides a detailed chronicle of the origins of the Power System Dynamic
Performance Committee and the various activities conducted under its auspicies. The
primary purpose of this document is to trace the history of the committee’s formation and
provide a historical time line for it evolution from a Working Group to a Committee.

The present committee had its origin as a Working Group under the System Planning
Subcommittee of the Power System Engineering Committee.

History of the Formation of the Working Group on Dynamic System Performance
The Working Group on Dynamic System Performance was organized in 1967 by Jerry
Ray, then the Chairman of the System Planning Subcommittee of the Power System
Engineering Committee. The scope and objectives of the Working Group were as
follows:

       Scope To promote and coordinate studies relating to the dynamic performance of
       power systems and interconnected areas. Dynamic performance as used here is
       intended to include all system behavior in which analysis of stability is involved.

       Objectives
       1. To coordinate the work on dynamic system performance being done by other
           IEEE groups, to avoid overlapping or omissions of important aspects of the
           subject.
       2. To promote joint workshops for purposes of education of those immediately
           engaged in problems of dynamic system performance.
       3. To promote and encourage papers and technical sessions jointly sponsored
           by the committees actively engaged in studies of dynamic system
           performance.
       4. To promote jointly sponsored technical conferences.

Mr. Wendal A. Morgan was chosen to organize and chair the Working Group, a position
he honorably served until his retirement from the post in 1972.




                                                                                             1
                        Mr. Wendal A. Morgan.




The Working Group was designed to serve the Power Engineering Society as a unit of the
Power System Engineering Committee and its System Planning Subcommittee. Liaison
was maintained with the following related units:

       Organizational Unit                              Represented by
       Relay Committee……………………………………………H. J. Sutton

       Computer & Analytical Methods Subcommittee……………P. L. Dandeno
       System Control Subcommittee………………………………A. A. Fouad
       Excitation Control Performance Working Group……………P. L. Dandeno

The Working Group has organized a number of Task Forces that have played an
important role in developing special activities of interest to the dynamic performance
specialists of our Society. These Task Forces and their chairmen are:

       Task Force                         Represented by

1975 PES Summer Meeting, San Francisco
        The major event sponsored by the WG at the 1975 Summer Meeting was a new
Symposium on Subsynchronous Resonance. This symposium was an overwhelming
success, with a large room packed with people spilling out into the hall. We were a bit
overwhelmed by the high interest in this subject, but obviously many wished to learn
about it and to take whatever measures might be necessary to prevent SSR from
damaging their generating units.

The symposium was titled simply “Subsynchronous Resonance” and was chaired by
 A. A. Fouad and R. G. Farmer and posted the following topics:
 Morning Session:
 Physical Principles Involved in SSR, Lee Kilgore, Westinghouse
 Cyclic Failure of Turbine Generator Shafts, Robert Quay, General Electric
 Project Reports:
1. Mohave Project, M. C. Hall, Southern Calif. Edison
2. Navajo Project, Eli Katz, LA Dept. of Water and Power

A meeting of interested parties was held in regard to the possible organization of a new
task force on “Heroic Control Schemes.”

Heroic Control Schemes were defined to include the following;
       1. Turbine fast valving
       2. Generator dropping
       3. Dynamic braking
       4. Series capacitor insertion

      2. Adopt suitable terms and symbols
      3. Provide information on the state of the art in problem
          analysis pertinent to the area



                                                                                           7

 1976 PES Winter Meeting & Tesla Symposium, New York
The major event sponsored by the WG at this meeting was a repeat of the SSR
Symposium, presented by the Task Force on SSR. The agenda for this all day symposium
was the same as that for the 1975 Summer Meeting symposium. The individual papers
from the symposium were compiled into a special publication, available from IEEE as
publication 76CH1066-0-PWR.




                                                                                    8
Richard P. Schulz was appointed as Liaison Representative between the Working Group
and the ASME Power Division. Mr. Schulz is a member of both the IEEE and ASME.
A special topic for discussion at the 1977 meeting of the Working Group was titled “An
application of Single Phase Switching at 765 kV,” presented by R. M. Makiszewski of
American Electric Power Service Corporation.

The DISCOS Task Force. Chaired by Peter Donalek, reported on several activities:
       Preparation of a bibliography
       Encouraging paper preparation
      Documentation of solution methods
      Documentation of test methods
      Providing guidelines for future research

 Wendall A. Morgan (M 34, SM 42, F 52) the first chairman of the Dynamic System
 Performance Working Group, died January 24, 1976 at the age of 76 from cancer. Mr.
 Morgan had retired in October 1975 as project engineer in charge of stability studies and
 special design projects at the Bechtel Power Corporation in San Francisco. He was an
 active member of the IEEE Power System Engineering Committee and organized the
 Dynamic System Performance Working Group in 1966, serving as chairman until 1973.

1976 PES Summer Meeting, Portland
The major WG activity at this meeting was the presentation of a System Symposium –
Reliability Criteria for System Dynamic Performance. The topics and presenters at this
all day symposium were as follows:

       Adequacy of existing reliability criteria
Panel Discussion, Panel Moderator, H. E. Pierce, Jr.
       Open discussion by panel members

Dr. Ed Kimbark presented a review of the history of the Working Group on Dynamic
System Performance and noted the strong level of activity. He offered the opinion that
the WG should petition the Power Engineering Committee to change the WG status to a
Subcommittee, and he presented this in the form of a formal motion. After a brief
discussion, the motion passed without dissent. Later this motion was presented by the
chairman, Paul Anderson, to the Planning Subcommittee, the WG parent organization,
and through them to the Power System Engineering Committee, where it was also
approved, with final action dependent on the Technical Operations Department (TOD) of
the PES. In the meantime, the chairman was advised to begin discussions regarding the
scope and organization of the pending subcommittee.

Mr. Al Kilgour, our liaison member to the Transmission and Distribution Committee
made a presentation at the meeting regarding the activities of the Stability Working
Group of the T & D Committee. He reported that a special Task Force has been set up to
study future involvement of the T & D Committee in this area, i.e., in system dynamic
performance, and he invited our chairman to attend, the meeting of this Task Force. The
Task Force did meet and discussed the overlapping interests of these two major
committees. Their recommendation was that the Dynamic System Performance Working
Group should become a full committee and that all activities related to dynamic
performance should be focused in this one committee. Moreover, they recommended that
work on this subject should be depreciated in the T & D Committee.

On December 6, 1976, the following draft scope was presented to W. H. Underwood,
Chairman, Power System Engineering Committee:

       Investigate various aspects of the dynamic performance of power systems at the
       level of a given machine, a company or area, or for an interconnected region.
       Initiate and coordinate studies, symposia, panel discussions and tutorials related to
       the subject. Cooperate with other interested groups in the development of
       standards that affect system dynamic performance.

       Coordinate activities, where possible, with other groups, in particular with the
       Computer and Analytical Methods Subcommittee through the CAPS Working
       Group.




                                                                                          10
        System dynamic performance relates to both linear analysis of systems,
        characterized by small disturbance conditions, and the nonlinear situations that
        result from faults, major network changes, or loss of generation or load.

1977 PES Winter Meeting, New York
The Dynamic System Performance WG primary activity at the 1977 Winter Meeting was
to present a repeat of the Symposium on Reliability Criteria for System Dynamic
Performance, this time under the chairmanship of A. A. Fouad. The agenda was the same
as that for the 1976 Summer Meeting Symposium. A special publication “Reliability
Criteria for System Dynamic Performance,” containing papers by all of the session
presenters was available for purchase as IEEE Catalog #77 CH1221-1-PWR.

Another event sponsored by the Working Group was a technical session,
“Subsynchronous Resonance,” chaired by H. L. Forgey, where four papers were
presented by members of the SSR Task Force and other industry participants.

Note that the SSR and Discrete Supplementary Controls task forces were upgraded, by
vote of the subcommittee, to become full working groups. Also, the ASME/IEEE Joint
Working Group has been approved by the PSE Committee and this recommendation is to
be forwarded to TOD for final approval.

The SSR Working Group agreed on the following scope of their activities:
      Treatment of technical matters pertaining to interaction among synchronous
      machines and their prime movers, excitation systems, the electrical network, and
      other subsystems which give rise to subsynchronous oscillations. Interfacing with
      other working groups concerned with such interactions.

Another feature of the SC meeting was presentation by Frank Delea and Dave Cristiano
of Consolidated Edison Planning Department on the July 13, 1977 New York blackout.

Another action taken at this meeting was the approval by TOD of a proposal to form the
ASME/IEEE Joint Working Group on Power Plant/Electric System Interaction. The
Joint WG will probably meet at the Joint Power Generation Conference. Initial members
are the following:
        Daniel D. Rosard………………………………ASME
        R. S. Couchman……………………………….ASME
        Heinz Termuehlen……………………………..ASME

       H. E. Lokay…………………………………….ASME & IEEE

The scope of the JWG was presented as follows:
       To identify and investigate the interactions between the plant and the power
       system that might prove to be detrimental or damaging to either and to promote
       assessment of techniques for preventing or controlling such hazards.
       To initiate and coordinate studies, symposia, panel discussions or tutorials related
       to the subject and coordinate with other interested groups in the development of
       definitions and procedures that affect plant/system interaction, control, and
       protection.

The proposed JWG was approved by the ASME Power Department and the IEEE Power
Engineering Society in 1978.

The DISCOS WG is preparing a panel for the next JPGC, which will include data from
testing of a new generating unit in Nebraska.

The CAPS WG is creating a task force to work on power plant modeling.

The DC Systems WG is preparing a two-terminal DC generic model, which should be in
draft form soon.

The Terms and Definitions TF reports that their draft of proposed terms and definitions
has been balloted by the Subcommittee, with 35 in favor and 1 opposed, and with six
respondents providing comments. It was moved that the TF paper be published in full in
the Power Engineering Review. This motion carried with two voting no.

The recent practice of concealing the names of authors to the reviewers of papers was
discussed. This practice will likely be dropped. In the discussion that followed, it was




                                                                                           18
moved that the SDP SC recommend to the PSE Committee that this practice be dropped.
The motion passed 10 to 9, which indicated the high level of disagreement on this topic.

The Subcommittee reviewed 22 papers for presentation at the 1981 Summer Meeting and
accepted 14 papers.

1982 PES Winter Meeting, New York
The subcommittee reviewed 22 papers for presentation at the 1982 Winter Meeting and
accepted 12 papers.

Anjan Bose has presented invitations to four individuals to participate in a panel session
“Application Experience with Direct methods for Transient Stability” to be held at the
1982 Summer Meeting.

P. Kundur has accepted the challenge of leading a task force on “Instrumentation for
System Dynamic Performance.” It is anticipated that liaison will be established with the
Relay Committee and the Power system Instrumentation and Measurements Committee.




P. Kundur


John Grainger has accepted the chairmanship of a new task force on the
“Effect of Harmonics on System Dynamic Performance”

A Committee report “Functional Model Structure for 2 Terminal HVDC Systems for
Transient and Steady-State Stability” is about complete and should be ready for the
Summer Meeting. The WG is also addressing model validation.

The WG on Harmonics under the T&D committee has been investigating harmonics on
the ac side of HVDC systems. They raise the question as to the appropriate machine
models for these studies. A discussion followed with the result that the chairman was
asked to set up a task force to investigate this question and report at the next meeting
regarding the scope of the problem and what action our subcommittee should take.

The Terms and Definitions TF is looking at block diagram usage and symbols. A total of
43 members and guests attended this meeting of the subcommittee.

The death of Ed Kimbark, a member of this subcommittee was noted with regret.




                         Dr. Edward W. Kimbark

Anjan Bose announced the formation of a panel on “Direct Methods-Applications and
Experience” to be held at this meeting on Friday. It was suggested that the panel be
repeated at the next Winter Meeting.

There was a lively discussion regarding the terms and definitions report from the Task
Force preparing that report. The IEEE paper was sent to CIGRE for comment, but no
comments were received.

The SSR WG is working on their second benchmark model and reviewing their terms and
definitions, which they feel have some shortcomings.

DISCOS is making plans for a panel session on Generator Dropping.

The Task Force on Harmonics is getting started. There seems to be much interest in this
subject.

1984 PES Summer Meeting, Seattle
In preparation for the 1984 Summer Meeting the subcommittee reviewed 24 papers and
accepted 12.

At this meeting the subcommittee received three important reports for consideration and
possible approval:
        Instrumentation for Monitoring of Power System Dynamic Performance,
        presented by the Task Force of the same name, P. Kundur, Chair.

       Conventions for Block Diagram representations, presented by the Task
       Force on Stability Terms and Definitions, A. Bose, Chairman
       Determination and Application of Synchronous Machine Models for Stability
       Studies, presented by the Joint Working Group of the same name, Paul Dandeno,
       Chairman

1984 Power System Engineering Committee Triennial Meeting
Williamsburg VA, October 28-31, 1984

Two items were introduced for discussion at this meeting:

One proposal was to change the name of the committee to the IEEE Energy Committee.
Most subcommittee chairmen offered suggested changes in subcommittee structure or
scope.

A suggested PSE annual publication devoted to a “review of technical developments”

The first item generated a huge amount of paperwork, but no action was taken. This idea
was discussed by the Subcommittee, but there was little enthusiasm for reorganization
and this conclusion was reported back to the PSE Committee.

The second item appears to have died without any formal action.

The subcommittee did not take any formal actions at this triennial meeting due to rather
small attendance by subcommittee members.

Two topics of current interest were presented for discussion by all subcommittees of the
PSE.
1) System Aspects of System Protection, and 2) The CIGRE Study Committee 38
Questionnaire on Analytical Tools.


       1. System Aspects of System Protection.
          The subcommittee held a round table discussion on this subject in which it
          was noted that system protection is often involved in large system upsets.
          Copies of written comments on the subject were provided by Charles




                                                                                       24
          Concordia, Dick Farmer, and Carson Taylor and these comments were
          thoroughly discussed.
       2. CIGRE Study Committee 38 Questionnaire on Analytical Tools.
          Subsequent to the meeting, Mr. Jack Prince, the U.S. Representative to SC 38
          has formed a group of 9 people to respond to the questionnaire and members
          wishing to contribute to this response were advised to contact one of this
          group of nine.

1985 PES Summer Meeting, Vancouver
Dick Farmer became the new chairman of the System Dynamic Performance
Subcommittee. Paul Anderson was commended for his leadership over the past 12 years.
In 1973 Paul took over a small working group and provided the dynamic leadership so
that in 1985 it had become a large subcommittee that had the largest paper load in the
Power Engineering Society.

prepare a paper dealing with the modeling of damping of turbine-generators for dynamic
analysis.

Felix Wu made a presentation on “Impact of New Trends in Inter-Utility Operations on
System Dynamic Performance” at the last meeting. It is suggested that Felix’s
presentation be made to others as part of a panel session at the 1996 Winter Meeting.



                                                                                        43
Aziz Fouad made a presentation on “Non-linear Interaction of Inter-Area Oscillation
Modes” at the last meeting. A survey of other utilities has been made to determine the
need and interest in pursuing this subject. The responses were generally favorable and
Aziz recommended that the Task Force continue its work under the chairmanship of
Vijay Vittal.

Dan Baker substituted for Einar Larsen and proposed that the Torsional Issues Working
Group Scope presented at the last meeting be accepted. The first sentence of the scope
was modified and approved by the Subcommittee.

Carson Taylor reported on the activities of the Special Stability Controls Working Group.
He reported that a paper “Annotated Bibliography on Power System Controls” has been
completed and will be presented at this PES meeting. A small benchmark system has
been assembled for use in the study of SVC application.

Prabha Kundur reported that the panel session on Long Term Stability at this PES
meeting was well attended and the presentations made by the panelists will be published
as a collection of mini-papers. Work has started on a special publication entitled
“Voltage Stability Assessment- Procedures and Guide.” The first draft is scheduled for
completion in a year.

Paul Anderson reported that the Stability Terms and Definitions Task Force work is
complete and Chairman Mansour will be provided with the resulting material. The
Chairman will distribute it to the Subcommittee for comment prior to the Task Force
finalization. It has been attached and sent with the minutes of this meeting.

Vijay Vittal reported that the Task Force on Stability Test Systems has received a HVDC
Test System from Serge Lefebvre which is now available from Iowa State University.


Transition to Becoming the Power System Dynamic Performance Committee of the
Power Engineering Society

As presented above the Power System Engineering (PES) Committee planned to divide
into 3 Groups with the System Dynamic Performance Subcommittee being grouped with
2 other subcommittees. The proposed grouping is repeated below:

       Bill Prince:
               System Operations Subcommittee
               System Control Subcommittee

       Lee Willis:
             System Planning Subcommittee
             Demand-side Management Subcommittee
             System Dynamic Performance Subcommittee



                                                                                         44
       George Gross:
             System Economics Subcommittee
             Computer and Analytical Methods

Bruce Wollenberg, PSE Chairman, sent a memo including the complete PSE Committee
proposed organization to the PSE Administrative Committee on October 6, 1995. The
memo included the following request:

      “The attached list shows the new structure of the committee with groups and their
      respective subcommittees. Please note that we indicated in the
      Summer meeting that there would be an opportunity at the Adcom to go over the
      new list of subcommittees and correct instances where there is an objection to this
      structure or to the subcommittee names, etc. I would like each subcommittee and
      each group to write a draft scope statement for the Adcom meeting in Baltimore at
      the 1996 Winter meeting. At the Adcom we can go over these scope statements
      and vote to approve, change or otherwise alter the structure and then submit them
      to the PES Technical Council for approval.”

The reorganization seemed to be proceeding without any major problems until the leader
of the group which was to include the System Dynamic Performance Subcommittee sent
an undiplomatic memo dated December 18, 1995 which included the following
statement: “We must split up the Dynamic Performance Subcommittee, Yakout. This is
non-negotiable and is supported all the way up the ladder, so let’s get it done.” The
following memo was sent to all members of the subcommittee.


On January 3, 1996 our chairman sent a landmark letter to all Subcommittee members
proposing that the Subcommittee seek Committee Status. The first page of this letter is
included on the next page.




                                                                                          45
46
At the January 23, 1996 Power System Engineering Adcom meeting Y. Mansour initiated
a discussion regarding the elevation of System Dynamic Performance Subcommittee to a
Committee status. The Adcom discussed this issue and voted to suggest to the Technical
Council to break up the PSE Committee into four committees effective January 1997.
These 4 committees would be:

       Power System Dynamic Performance
       Power System Operations
       Power System Planning
       Power System Analytical Methods and Economic Analysis

At the January 24, 1996, Subcommittee meeting the following motion was made and
passed with a vote of 35 to 0: “Recommend to elevate the System Dynamic Performance
Subcommittee to a Committee status named Power System Dynamic Performance
Committee with the original scope retained until a new scope is formulated.”

On April 18, 1996 Yakout Mansour sent a letter to Bruce Wollenberg proposing the
following organization for the Power System Dynamic Performance Committee:
       Chairman:              Yakout Mansour
       Vice Chairman:         Richard G. Farmer
       Secretary:             Vijay Vittal

       Power System Stability Subcommittee:
       Chairman: Prabha Kundur

       Power System Stability Controls Subcommittee
       Chairman: Carson W. Taylor

       Power System Dynamic Modeling Subcommittee
       William W. Price

       Working Group on Torsional Issues
       Chairman: Einar V. Larsen

       Working Group on Dynamic Security Assessment
       Chairman: Peter W. Sauer

       Recognition and Fellowship Working Group
       Chairman: Felix Wu

Technical Council approved the reorganization and the new Power System Dynamic
Performance Committee officially became part of the PES Technical Council at the 1997
Winter Meeting in New York.




                                                                                   47

The Chairman explained the new process for handling papers and developing
meaningful material for PES Meetings. This was based upon a paper prepared by
Don Russell and modified by the PES Board of Governors. The new process is
summarized as follows:
1. A technical Chairman and supporting Committee will be named for each
   General Meeting with responsibility for planning its technical program for one
   specific General Meeting. This will include a call for papers a year or more in
   advance and flexibility to focus and design the technical program using any
   combination of paper sessions, panel sessions, poster sessions, symposia,
   tutorials, etc.

2. For each General Meeting a Proceedings will be published before the meeting
   and will include the conference papers and a 2 – 6 page summary of panel
   sessions. Transactions papers will not be included.

3. An Editor-in-Chief for each of the Transactions will be named with an Editorial
   Board consisting of a cross-section of experts in the applicable areas.
   Publication of papers in the Transactions will be totally and completely



                                                                                56
        decoupled from the programs of any meeting.

      Carson Taylor reported that Mike Henderson is organizing and chairing a new
      working group on Planning Requirements of FACTS devices. The working group
      will be under the T&D Committee with Mike providing liaison to the Power

1999 PES Winter Meeting, New York

      Vijay Vittal reported on the new PES paper review procedures which are very
      different for Proceedings papers and Transactions papers. Proceedings papers are
      based on a schedule to fit a specific meeting and have the following steps:
      Abstract submittal, Conditional acceptance, Full paper submittal, Paper
      acceptance or rejection, Presentation of accepted papers at a summer or winter
      meeting. Transaction papers are submitted at any time and the time required for
      the review process will determine the schedule for publishing the accepted papers
      in the Transactions. Vijay discussed the initial plans for PES electronic technical
      paper review & publication process.

      Dick Farmer reported that the Technical Council Technical Sessions
      Improvement Committee will provide for slide overhead projectors at all technical
      sessions and authors should provide their own computer driven projectors.

      Yakout Mansour reported that there were 39 Transactions papers and 32
      Proceedings papers reviewed by the Committee prior to this meeting.

      The Committee did not sponsor any classical paper sessions at this meeting.
      Instead 3 poster sessions were sponsored which included 39 papers displayed in
      the form of posters.

2000 PES Winter Meeting, Singapore

      The Secretary, Goran Anderson, reported on the meeting that he attended of the
      Organization & Procedures Committee. Much of the discussion was focused on
      re-organization of PES. Such a change may take place over the next 2 year.

      The Chairman, Vijay Vittal, reported the following:
            The Technical Chair for the 2000 Summer Meeting will be Anjan Bose.
            PES directory will only be available on the Web in the future

             NERC has approached IEEE PES for writing new planning and operations
             standards. The first standard to be written will be on operator training.

             The major discussion at the Technical Council meeting was related to
             reorganization of PES. A proposed reorganization will be circulated to the
             committees and their members. The Committee will formulate a response
             to the Technical Council.

             The editorial board for the IEEE Transactions under PES will be:
                    Transactions on Power Systems: Murty Bhavaraju
                    Transactions on Power Conversion: James Kirtley
                    Transactions on Power Delivery: Arun Phadke
                    Associate editor from PSDPC in Trans. On Power Systems:
                             John Paserba
             Electronic submission of Transactions Papers is mandatory. The review
             process will become completely Web based during the year 2000. It was
             requested that the practice of sending reviewers the other reviewer’s
             comments on the same paper will be followed.

             Since spring of 1999, 23 papers have been reviewed and 9 were accepted.

             A Recognition Working Group of the Power System Dynamic
             Performance Committee has been formed with Dick Farmer as Chairman.
             Proposed Guidelines for Recognition and Awards has been prepared.
