Accident standby energy storage power station access point and access capacity optimization coordination configuration method

Abstract

The invention discloses an accident standby energy storage power station access point and access capacity optimization coordination configuration method. The method comprises the following steps: S1, searching and sorting required data; s2, establishing a configuration model containing a target function and constraint conditions; s3, solving an optimal access point by using a solver; s4, carrying out N-1 safety inspection, and determining accident reserve capacity; and if the security check is not passed, adding a constraint condition and substituting the constraint condition into S3 for re-solving until the security check is passed. According to the invention, energy storage with rapid response is regarded as accident reserve resources, and the energy storage accident reserve required by the system is optimally configured with the purpose of meeting the accident reserve demand. According to the method, the maximum economic benefit of safety in the N-1 state of the power grid is ensured, the problem of optimal configuration of the energy storage power station considering accident reserve is solved, and the advantages of the energy storage technology with the rapid adjustment capability in the aspect of accident reserve are fully played. The method has good applicability, and actual requirements are well met.

Description

technical field [0001] The invention relates to the technical field of electric energy storage, in particular to a method for optimizing and coordinating configuration of access points and access capacity of emergency backup energy storage power stations.
