Study on The Operation Strategy of Electrochemical Energy Storage Station with Calculation and Efficiency Conversion

To achieve a more economical and stable operation, the power output operation strategy of the electrochemical energy storage plant is studied because of the characteristics of the fluctuation of the operation efficiency in the long time scale. Second, an optimized operation strategy for an electrochemical energy storage station is presented based on the proposed efficiency transformation model. The energy storage station's economic efficiency and load-smoothing effect are studied. Finally, the proposed optimization strategy and operation indexes are verified by calculation and simulation comparison with an example of an energy storage station in Guangdong. The results show that the proposed operation strategy of electrochemical energy storage station has an excellent technical economy.
