Enhanced Simulation Tools for Scheduling Solar Plus Storage Power Plants

Summary

The challenge addressed is the inadequate capture of long-duration energy storage (LDES) value in existing power system models, which limits the optimal scheduling of solar-plus-storage plants. The approach involved developing and disseminating new methodologies and enhanced simulation tools, comparing various dispatch mechanisms using industry-accepted grid modeling tools. The project is completed and found that LDES significantly improves grid reliability and reduces costs, with most technologies demonstrating a benefit-cost ratio greater than one, though traditional one-day optimization horizons are inefficient for LDES dispatch.
