Abstract: Firstly,the evaluation models of multiple application value and operation cost of energy storage are constructed. Then,the performance index and comprehensive performance index model of energy storage indirect value related service types are established,and the multi-type application operation strategy of energy storage system is put forward. Finally,the simulation analysis is carried out based on the typical case. The results show that the proposed method can guide the multiple application and optimal operation of energy storage at different grid connected nodes in the power grid.
