Abstract:

From the point of view of peak shaving compensation and coal saving,a capacity configuration and coordinated control method of energy storage participating in power grid auxiliary peak shaving based on the minimum operating cost is proposed.Aiming at maximizing the net profit of the system,the optimal capacity configuration model of energy storage participating in auxiliary peak shaving is established.ABC and PSO algorithms are respectively used to solve the model for the optimal capacity configuration of energy storage systems.With the minimum operating cost of the system as the objective function,an optimized control model for energy storage to participate in the auxiliary peak shaving of the grid is established.After coordination and optimization,the system wind abandonment rate is reduced to 1.078 8%,and the total system operation cost has been reduced to 1 401.08 million yuan.The validity and correctness of the method are verified by simulation analysis of the actual operation data of a power grid in a province.

Key words: energy storage system, auxiliary peak shaving, capacity optimization configuration, coordinated optimization
