Abstract The current operating mode of energy storage participating in auxiliary services is not perfect, which fails to give full play to the regulating ability of energy storage. To solve this problem, this paper considers that the energy storage power station participates in peak shaving service, frequency modulation service and energy market at the same time. Combined with the intraday forecast curve of the regional power grid and aiming at the lowest operating cost of the regional power grid, this paper constructs the regional power grid optimization model and use YALMIP to call CPLEX for simulation in Matlab. The calculation example shows that under the operation mode proposed in this paper, the capacity utilization rate of the energy storage power station improves, the income of energy storage system increases, and the economic efficiency of regional power grid improves.

Key words： regional power grid energy storage system auxiliary service market operation optimization
