2009 Scenario Reliability Assessment - NERC

Regional Reliability Scenario Self-AssessmentsPartial List of Current/Past Variable Generation Study Activities in the WesternInterconnectionAESO Wind Integration Impact StudiesThe purpose of these studies was to assess the impact of existing and additional levels ofwind capacity on the safe and reliable operation of the Alberta Interconnected ElectricSystem, and to assess the merits of mitigation measures to maintain acceptable systemperformance.Alberta Wind System Impact Study & Dispatch Simulation ModelThe AESO developed a dispatch simulation model to be used for analyzing and assessingthe operational impacts of wind power and the effectiveness of new mitigating measures.AESO development of technical requirements for wind power facilities.AESO Wind Power Forecasting Pilot ProjectThe purpose of AESO’s pilot project was to test various wind power forecasting methodsand providers, and to identify the most effective methods/providers to forecast windpower in Alberta.Market & Operational Framework for Wind Integration in AlbertaThis framework will form the foundation for work required to further refine and definerules, tools and procedures needed to integrate as much wind power into the Albertasystem as is feasible without compromising system reliability or the fair, efficient andopenly competitive operation of the market.BPA Simulation of Wind Generation in Resource Adequacy AssessmentsStudy investigates the reliable capacity available from wind generation in the BPA BA,the correlation of wind generation and temperature, and creating long-term synthetic datarecords.2007 CAISO Study in Integration of Renewable Resources (IRRP)Purpose of the study is to identify integration issues and solutions for the integration oflarge amounts of renewable resources into the ISO Control Area. Particular focus onaccommodating 20 percent and 33 percent RPS.2007 CEC Study – Intermittency Analysis ProjectThe study examined several aspects of large scale development of intermittent renewableresources, principally in California, but also in related areas which might be exportedspecifically to California.Idaho Power Wind Integration StudyThe study identified operational impacts of integrating wind generation into IdahoPower’s existing resource portfolio and outlined a basic approach for integrating the windas studied.Joint InitiativeSponsored by ColumbiaGrid, NTTG, and WestConnectThe goal of the JI is to encourage and facilitate Western Interconnection parties to jointlydevelop and implement high-value cost-effective Regional products to assist with theintegration of non-dispatchable resources.2007 NW Wind Integration Action Plan and 2009 Phase II StudyEfforts address the challenge of how to best integrate wind energy into the PacificNorthwest’s existing hydro-rich electricity system.WECC Modeling and Validation Work Group proposed standard for submittinggenerator models for WECC base cases.CAISO Storage Pilot Program2009 Scenario Reliability Assessment Page 171
