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
Regional Reliability Scenario Self-AssessmentsEfforts to accommodate storage devices with limited storage capability in connection withFERC Order 890.PNNL study in conjunction with BPA and CAISO on Wide Area Energy Storageand Management System to balance intermittent resources. The study assessesregulation sharing opportunities and assesses the effect of fast regulation resources.NREL/Oakridge study to quantify the benefit of combined BA operations on ramprequirements in systems with significant wind penetration.NREL/WestConnect/GE study of large scale wind integration in WestConnectfootprint and the impacts of combined BA operations.NREL study to investigate the capacity and ramping impacts of wind energy onpower systemsThe study identified opportunities for improving the efficiency of inter-BA windtransfers.NREL study on tariff design and its influence on the availability of ancillaryservices.BPA use of software to modify variable generation output with over generationcondition and reserve levels depleted and modifying tags when under generationcondition exists and reserve levels depleted.PG&E development of prototype tool to estimate required regulation, loadfollowing, and day-ahead commitment capacity, and integration costs for differentlevels of intermittent resources.In addition to study activity in the Western Interconnection, there have been a number of pilotprograms and operational changes to facilitate the integration of variable generation. Theseinclude balancing cooperation agreements between BAs, ancillary service agreements, andchanges to transmission tariffs. Two examples of these are described below.The ACE Diversity Interchange (ADI) is an example of BA cooperation to reduce the impacts ofvariable generation. It provides a mechanism for BAs to share their variability, which reduces thelevel of generation changes required by each entity. There are currently 16 BAs in the WesternInterconnection participating in this activity. For the entities involved, participation has beenshown to reduce balancing costs and improve NERC Control Performance Standard (CPS2)scores. 114The Joint Initiative is a voluntary joint project sponsored by ColumbiaGrid, Northern TierTransmission Group, and WestConnect. Collectively, these three Regional planning groupscover most of the two non-ISO areas of the Western Interconnection. In addition, the project hasmany participants among WECC member utilities, merchants, and stakeholders. The goal of theJoint Initiative is to tap into the existing flexibility that exists within the WesternInterconnection. The Joint Initiative is recommending changes to Transmission Service Providerbusiness practices to: Facilitate within-hour transmission purchase and scheduling. Developing tools to facilitate within-hour bilateral transactions.114 http://www.columbiagrid.org/ace-diversity-overview.cfmPage 1722009 Scenario Reliability Assessment
