The pooling station is connected to a power grid; the capacity optimization configuration method comprises the following steps: S1, designing an energy storage sharing mechanism based on a new energy power station group distributed shared energy storage architecture; s2, establishing a new energy power station group distributed shared energy storage cooperative game model considering factors such as on-grid electricity revenue and shared energy storage revenue; and S3, taking new energy power station group sharing in the same pooling station environment as a scene, taking the energy storage capacity constructed by each new energy power station as a decision variable, and solving an energy storage optimization configuration result by using a particle swarm algorithm. The pressure of power grid dispatching is reduced, and the energy storage cost and the construction scale are reduced.

Description

technical field [0001] The invention belongs to the technical field of heating system detection and protection, and in particular relates to a capacity optimization configuration method for shared energy storage of a new energy power station. Background technique [0002] With the rapid development of new energy power generation technology, rational planning of new energy power stations is the basis for ensuring the economic development and reliable operation of power systems. Due to the randomness and intermittency of different new energy power generation methods, and the need to reduce wind power errors, the configuration of energy storage in new energy power stations can stabilize the random fluctuations caused by power generation and improve the output characteristics of the power station. However, the high cost of energy storage construction and the size of the power station's self-provided energy storage have brought challenges to the large-scale development of new ene...
