DRAFT WSCC Information Management Subcommittee Meeting September 19, 2000 Folsom, CA The reader is advised that these minutes have not been approved. Therefore, Introductions agreement regarding the contents of the Sam Hess PacifiCorp minutes has not been confirmed with all Dave Ambrose WAPA Loveland participants. Bill Comish WSCC Jerry Mossing Alberta Power Pool Gregory Travis Idaho Power Company Carol Malugani California ISO Blane Taylor Xcel Energy Terry Doern BPA EHV Data Pool White Paper Bill Comish reported that Ralph Underwood has been tasked to make changes to white paper and release. Bill reported that the California ISO has issue with publishing of generation data. Per the California ISO (Ed Riley), this violates the California ISO tariffs which restricts publishing of the data to 90 days after the fact. Ed Riley has said will make the data available to reliability entities only. Dave Ambrose believes this can be accomplished within the existing EHV data pool and not forward the data to the web site. Bill Comish to follow up with Ed Riley. The function of the data pool is to collect and disseminate information related to the EHV Data Pool to reliability entities. Since 4-5 entities had not yet separated their market and grid operations, a web site was created. The web site goes to the merchants and the EHV Data Pool is restricted. For example, ACE data is not forwarded to the web page. Every 60 seconds, data is forwarded to the web site server. Data pool update is every 10-20 seconds. An updated document dated 9/19/00 was reviewed by the IMS at the meeting, The document incorporated comments from a 9/7 conference call held by the OC group tasked with writing the white paper and several control area operators. Comments were as follows: • Provide description of the EHV Data Pool architecture and its relationship to the web site. DEWG Report: Dave Ambrose Status of Migration for X.25 • Dave Ambrose provided an update on the status of X.25 migration. This effort is dependent on WSCC Net migration from WEIC to ICCP which should be completed by 1/01. Every control area must have an IP connection to the WON. Bill Comish stated that WSCC will have its connection shortly. • Bill Comish provided an update to Dave Ambrose on generation data that is missing in the EHV Data Pool at this time. Dave Ambrose to verify. Bill Comish to prepare letter for Blane Taylor to send out to the OC rep of the control area where data is missing. Approximately 20,000 mw of capacity are missing from the pool. DRAFT • The Data Exchange WG is also working on tracking the Security Coordinator collection of monitoring data that is due 1/01. Status of Master-ID Proposal: No new status. NERC is still working on finalizing the format. The establishment of unique ids should help in maintaining electronic maintenance of models. Also, DEWG is working on adopting NERC format for ICCP points available from a system. This has been distributed to the DEWG mailing list. Status of NERC ACE Project: Collection of ACE data by the EHV Data Pool and forwarding to NERC. Seven companies are not providing. Six are willing, but the seventh has declined. Dave reported that NERC has requested voltage data from the EHV Data Pool to do voltage profiling. Blane to follow up on why the item on agenda re: Security Coordinators signing Confidentiality Agreement. WSCC Net/Messaging System: Testing underway with 4-node network. California ISO, AEPC, Idaho, and WAPA Phoenix are doing testing. Proposal to be presented at upcoming OC meeting. Five documents due 9/25 for review by DEWG with comments due back by 9/28. Conference call on 9/29 to finalize for OC approval at 10/4-5 meeting. In the new system, not everyone is a server as is the case currently. Proposals being considered: 1. 2 clusters – California ISO and WAPA Loveland. – with stand-alone backup. Estimated capital cost of $80,000 plus on-going support costs. 2. 3 stand-alone machines – primary, backup, tertiary with no failover. Estimated capital cost of $35-40,000 plus on-going support costs. Difference is in licensing and clustering. 3. 2 stand-alone machines with simultaneous log-ins. Estimated capital cost is $25,000 plus on-going support costs which will be higher than in options 1 and 2. Issue is no $ in 2001 WSCC Budget; however, there is $20,000 in 2000 budget. Discussion centered around recommending Alternative 1 presenting costs and benefits, Utilities should benefit from reduced costs with the elimination of the X.25 requirement (packet switches, TX2000 cards) within their companies. Dave Ambrose to get final estimates for the OC meeting as well as projected costs savings and benefits. Voice over IP on the WON: California ISO had submitted request to run VoIP over WON. DEWG requested CAISO run test between Security Coordinators. California ISO to develop project schedule and task list. Data Exchange Work Group has implemented process for requesting/approving new data exchange applications to be added to the WON. DEWG will review and make recommendation for IMS approval. WON Security: WSCC Network Security Policy being prepared by the Data Exchange Work Group. Draft provided by Dave Ambrose for review by IMS. Comments were provided to Dave to take back to the WSCC Data Exchange Work Group. DRAFT Status of Availability/Reliability Statistics on the WON: CAISO to provide channel utilization statistics on the ECN for that part which is WON and develop a network map with IP addresses. Status of Router Configurations on the WON: Outside resources will not be required for this effort. Was this money budgeted in the 2000 WSCC budget and could it be utilized for the WSCC Messaging System work? Action Items: NWPP Coordinated Outage System (COS): Investigate use by the WSCC. Is this a requirement under FERC Order 605? Meeting Schedule: 4/24-25/01 in Boise Greg Travis 8/28-29/01 in Calgary Jerry Mossing EMSWG Status Report: Terry Doern EMS Security: EMSWG has developed draft Purpose, Scope, Practices, and Problem Statements. EMSWG participants are to provide their company policies to be used in the creation of WSCC EMS Computer Security Guidelines. Advanced Applications: Costs, Benefits, Usage. IMS recommended adding description that targets purpose of the programs. Break Advanced Applications work into three groupings: • State Estimator and Power Flows (Online Power Flow, Dispatcher Power Flow, and Optimal Power Flow) plus the IMS added Contingency Analysis into this list. • Voltage and Dynamic Stability Assessments • Total Transmission Capacity and Available Transmission Capacity IMS directed that the EMS WG develop descriptions of the Advanced Applications, current usage within the WSCC community, and develop costs and benefits for each of the applications. WSCC Critical Path Sanction Avoidance: Once limit exceeded, need countdown timer from time exceeded limit. Add trending of current path mw value and the limit. August 10 CMOPS Action Item: Terry Doern reported that this item has been completed with re-submittal of electronic copy of the original report to WSCC. In addition, the EMS Emergency Guidelines document has been sent to WSCC for posting on the Web. EPRI Common Interface Model: Terry Doern reported that the WSCC EMSWG has an interest in this EPRI Project. Action items of the work group including evaluating the CIM for use in Advanced Applications, developing specifications for EMS/Advanced DRAFT Applications usage, determining the state of the current EPRI project and the IEEE Standard. Quality of EHV Data Bill Comish reported problems with missing data particularly path limits. Bill provided a list to Terry Doern for follow-up. Dave Ambrose is going to remove phase shifter data and transfer limits for Cut Planes. Dave has new Path Look-Up table from Bill Comish for installation on the EHV Web Site. Also, issues with BPA sign convention on generation data. The root of the problem is that there is no standard. Defacto convention of the WSCC is that it is the responsibility of the receiver to transform the sign to their internal convention. Dave Ambrose reported that there is a new NERC standard that addresses sign conventions, but does not address sign convention for data that crosses paths. ICCP Performance Development Comments should be forwarded to Dave Ambrose by the end of November. The DEWG meets in December 2000.
