SYSTEM REVIEW WORK GROUP

Revised 7/17/2012

Establishment and Authority

The System Review Work Group (SRWG) is a member work group established by the Technical Studies Subcommittee (TSS) under the Planning Coordination Committee (PCC).

Purpose/Responsibilities

The purpose of the SRWG is to implement and monitor guidelines and policies as developed by the TSS and SRWG pertaining to power flow and dynamic data requirements. The SRWG also works to ensure accurate system representation and to monitor system performance in compliance with NERC Reliability Standards and WECC System Performance Criteria. for the development of interconnection-wide models necessary to support analysis of the reliability of the interconnected transmission system. The interconnection-wide models and associated data should support WECC members’ ability to meet requirements of North American Electric Reliability Corporation (NERC) Standards and other needs as deemed necessary by WECC members.

The SRWG shall:

  1. Compile a data bank of solved near- and longer-term power flow base cases with associated stability data for selected study years and seasons.interconnection-wide models..
  2. Work with other WECC committees or groups to propose the base cases and study criteria to be included in the data bank. Prepare the case description sheets specifyingspecifications for system configurations, scenarios, and operating conditions of the models.
  3. Propose and coordinate schedules for data compilation, distribution, review, and approval of casesthe models.
  4. Monitor data submission for appropriateness and coordinate data issues as required with member utilities and other data owners.
  5. Plan and reviewAssess the annual assessmentquality of near-terminterconnection-wide models compiled.
  6. Develop metrics and futuremonitor results.
  7. Work jointly with Modeling & Validation Work Group (MVWG) to compare compiled interconnection-wide models to actual system performanceconditions and events from an interconnection-side perspective.

Annually prepare the summary of an outline for a study plan including descriptions of power flow and stability cases to be run. Use TSS recommendations covering general areas of interest, types of operating and transfer conditions, and types of disturbances to be studied.

Review study results and prepare reports.

b.Define system representation in WECC power flow and stability studies.

  1. Prepare and maintain system representation guidelines to be used by member and non-member systems for submitting data and monitoring complianceMonitor NERC Standards related to modeling and simulation of the transmission system.
  2. Develop data requirements and implementation plans.
  3. Participate as requested by the TSS in WECC computer programin transmission system data management and simulation software development and testing. Continue to investigate
  4. Investigate how technology can improve the WECC base case submittalSRWG guidelines and review process. policies.
  5. Work to ensure interchangeability of all data among users of different programs within WECCsoftware.
  6. Perform such other functions as may be delegated by the TSS. The Planning Coordination Committee (PCC) Steering Committee should be informed of SRWG or member system workload associated with special assignments.

Committee Composition and Governance
