Large-scale energy storage power station power cooperative control method considering economy and safety

The invention discloses a large-scale energy storage power station power cooperative control method considering economy and safety. Starting from the purpose of optimizing an energy storage system to economically respond to a power grid dispatching instruction, when an energy storage power station receives a power instruction of a power grid dispatching center, fault detection is firstly performed on each battery pack, SOC information is collected, a power constraint factor of each battery pack is calculated, and if the state information of each battery pack, such as the number of effective battery units, SOC states and the like, is consistent, the power constraint factor of each battery pack is calculated; each battery pack bears the dispatching power in an average distribution mode; and if the state information of each battery pack is inconsistent, the optimal output power of each battery pack is calculated and distributed by taking economic optimization as a target, each unit in the battery pack responds t
