Abstract

The invention discloses a supplementary planning method and system for a distributed energy storage system oriented to distribution network convergence applications. The method includes: establishing the convergence potential of at least one typical type of distributed energy storage resources in a distribution network Model; establish a supplementary planning and configuration model of an energy storage system based on existing energy storage resources under the condition of promoting the application of distributed power consumption; use an optimization algorithm to solve the supplementary planning and configuration model. The present invention utilizes the existing distributed energy storage resource layout in the active distribution network, faces the demand of the distribution network, and based on the existing available energy storage resources, carries out supplementary energy storage planning on this basis, which can make full use of the existing Some distributed energy storage resources can improve energy storage efficiency, reduce re-investment in the power grid, save costs, and improve the economy of power grid operation.

Description

technical field [0001] The present invention relates to the technical field of distribution network energy storage, and more specifically, to a supplementary planning method and system for a distributed energy storage system oriented to distribution network convergence applications. Background technique [0002] With a large number of distributed power sources connected to the distribution network, the uncertainty of its output has brought increasingly severe challenges to the planning and operation of the distribution network. At the same time, problems such as rapid load growth and increasing peak-to-valley differences It is highlighted that load demand response, as an effective adjustment method, can alleviate the above problems to a certain extent, but to fundamentally solve it, it is necessary to introduce distributed energy storage. [0003] In recent years, distributed energy storage has developed rapidly, and its installation location is flexible. Compared with centr...
