Energy storage will play a critical role in providing flexibility in power systems having high levels of integrated renewable energy sources. Unlike other generating resources that have long and reliable useful lifetimes, electrochemical energy storage (EES) suffers from a range of degradation issues that vary as a function of EES type and use. Although several studies have explored ways to account for the degradation cost in investment and operational decisions for various applications (for example, electric vehicle charging/vehicle to grid, microgrid management, energy arbitrage/peak shaving, frequency regulation, multiservice, etc.) a comprehensive and rigorous approach that optimally valuates and manages EES degradation over different decision horizons is still unknown. This innovation is an intertemporal decision framework, which, first, coordinates short-term, mid-term and long-term EES scheduling to optimize the life-cycle benefit considering EES degradation, and, second, uses the estimated operational revenue to facilitate investment and subsidy decisions at the planning stage.
