A network-configuration type energy storage planning and configuration method based on operation requirements

Abstract

The application discloses a network type energy storage planning and configuration method based on operation requirements, relates to the technical field of power system stability analysis and new energy power generation planning and control, and comprises the following steps: obtaining total power planning requirements and total energy planning requirements; performing time domain simulation, quantifying simulation results into stability margins, and extracting power support requirements and energy adequacy requirements; taking voltage stability sensitivity and the power support requirements as weights to generate initial power allocation, and taking the energy adequacy requirements as weights to generate initial capacity allocation; converting resonance stability analysis results of the target power grid into stability constraint boundaries, taking the initial power allocation and capacity allocation as optimization starting points, taking an investment return function considering a penalty term corresponding to the stability margins as an objective function, performing optimization iteration, and outputting configuration instructions. The application is used to solve the energy storage collaborative configuration problem under the strong coupling of transient support and resonance boundaries in the prior art.
