Analysis and Comparison for The Profit Model of Energy Storage Power Station

The role of Electrical Energy Storage (EES) is becoming increasingly important in the proportion of distributed generators continue to increase in the power system. With the deepening of China’s electricity market reform, for promoting investors to construct more EES, it is necessary to study the profit model of it. Therefore, this article analyzes three common profit models that are identified when EES participates in peak-valley arbitrage, peak-shaving, and demand response. On this basis, take an actual energy storage power station as an example to analyze its profitability by current regulations. Results show that the benefit of EES is quite considerable.
