Eastern Wind Integration and Transmission Study David Corbus - Project Manager Matt Schuerger (Consultant) National Wind Technology Center NREL Golden, Colorado USA 303-384-6900 David_Corbus@nrel.gov MattSchuerger@earthlink.net
Objectivesof Eastern Wind Integration and Transmission Study (EWITS) • Evaluate the power system impacts (operating due to variability and uncertainty of wind; transmission; reliability) associated with increasing wind capacity to 20% and 30% of retail electric energy sales in the Joint Coordinated System Plan region (MISO/PJM/SPP/TVA) by 2024; • Build upon prior wind integration studies and related technical work; • Coordinate with Joint Coordinated System Plan (JCSP) and current regional power system study work; • Produce meaningful, broadly supported results through a technically rigorous, inclusive study process.
Key Issues & Questions include • What are the benefits from long distance transmission that accesses multiple wind resources that are geographically diverse? • What are the benefits from long distance transmission that move large quantities of remote wind energy to urban markets? • What are the cost/benefits of remote wind resources that require transmission versus lower wind speed local wind resources? • How much does geographical diversity help reduce system variability and uncertainty?
Key Issues & Questions include • What additional system operational impacts and costs are imposed by wind generation variability and uncertainty? • What is the role and value of wind forecasting? • What benefit does balancing area cooperation or consolidation bring to wind variability and uncertainty management? • How does wind generation capacity value affect reliability?
Wind Integration Methods & Best Practices • Capture system characteristics and response through operational simulations and modeling; • Capture wind deployment geographic diversity through synchronized weather simulation; • Match wind output with actual historic utility load and load forecasts; • Use actual large wind plant power statistical data for short-term regulation and ramping; • Examine wind variation in combination with load variations.
Wind Integration Methods & Best PracticesCont. • Utilize wind forecasting best practices and combine wind forecast error with load forecast error; • Examine impacts of Balancing Area consolidation and fast markets.
Key Tasks- Eastern Wind Integration & Transmission Study • Three main tasks • Mesoscale wind resource modeling and development of wind power plant outputs 2) Transmission Analysis (with JCSP) 3) Wind integration study
Key Tasks- Mesoscale wind resource modeling • Develop high quality wind resource data sets for the wind integration study area (mesoscale modeling, 3 years)
Key Tasks- Eastern Wind Integration & Transmission Study • Identify wind power generation sites for 20% & 30% wind energy scenarios • More than 300 GWs of total wind power data generated in time series for 3 years! • 135 GWs for 20% energy and 200 GWs for 30% energy scenario
Key Tasks- Transmission Analysis • Develop transmission plan (coordinated with JCSP) • Run hourly dispatch/market models
Joint Coordinated System Plan (JCSP) • The 2007/2008 Joint Coordinated System plan will include MISO, PJM, SPP, and TVA • The JCSP will perform a long term planning study incorporating both economic (2024) and reliability (2018) analysis of system performance for the combined four JCSP areas • Collaboration with the parallel DOE Eastern Wind Integration & Transmission Study will provide underlying assumptions for generation scenarios • Scheduled to be completed December 2008
Key Tasks- Eastern Wind Integration & Transmission Study • Evaluate operating impacts and associated costs • Regulation • Load Following • Unit Commitment • Evaluate reliability impacts (ELCC/LOLP)
Technical Review Committee (TRC) • A TRC will be formed with regional and national technical experts on wind generation and power systems analysis to help guide and review the study • The TRC will review and provide feedback on key assumptions, methods, and preliminary results • It is anticipated that the TRC will meet quarterly throughout the study
Preliminary Schedule • Nov 07 – Feb 08 Study Development and Stakeholder input • January 2008 Award Wind Mesoscale Modeling Contract • February 2008 Award Wind Integration Contract • Jan – Oct 2008 Develop Wind Data Sets • April – Dec 2008 Develop Transmission Plan in Coordination with JCSP • Sept 08 – May 2009 Evaluate Operating & Reliability Impacts • June 2009 Complete Study
