Based on the characteristics of peak-shaving and valley-filling of energy storage, and further consideration of the changes in the system''s load and real-time electricity price, a model of additional potential benefits of energy storage is developed. the generation shortage is large and the real-time electricity price is at a peak, and
Simultaneously, the peak-shaving energy storage can get benefit from the arbitrage while facing the energy loss and operation and maintenance (O&M) cost.
