Abstract

The invention discloses a power grid side energy storage optimization method and system. The method comprises the steps of obtaining power grid side energy storage data, and determining a power grid side energy storage optimization objective function according to the power grid side energy storage data; wherein the objective function considers a delayed power transmission network upgrading and reconstruction factor, a wind power consumption factor, an energy storage peak regulation factor and an energy storage system life factor; and optimizing the power grid side energy storage configurationby adopting a longicorn beard search algorithm according to the target function and the constraint condition. By the adoption of the method and system, energy storage can be reasonably configured, resource waste is reduced, and energy storage cost is reduced.

Description

Technical field [0001] The invention relates to the technical field of grid-side energy storage, in particular to a grid-side energy storage optimization method and system. Background technique [0002] The application of large-scale energy storage technology in the power system is becoming more and more widespread. The planning of energy storage in the power system has attracted more and more attention, but the traditional grid-side energy storage optimization method is unreasonable to configure energy storage, resulting in Power grid resources are wasted. Summary of the invention [0003] The purpose of the present invention is to provide a grid-side energy storage optimization method and system with reasonable configuration of energy storage to reduce resource waste. [0004] In order to achieve the above objectives, the present invention provides the following solutions: [0005] A grid-side energy storage optimization method, including: [0006] Obtain grid-side energy storage d...
