Abstract

The invention discloses a test and evaluation method of a distributed energy storage system, which relates to the technical field of electric energy storage; it includes the following steps, the first step is to obtain the output data of the distributed energy storage system, and the second step is to use k-means The clustering algorithm clusters the output data of the distributed energy storage system. The third step is to select the working condition performance reference test mode according to the clustering results and carry out the test. The fourth step is to record the basic parameters of the distributed energy storage system. The fifth step , to calculate the evaluation index of the distributed energy storage system; through the first to fifth steps, etc., it realizes the evaluation of the application condition performance of the distributed energy storage system.

Description

technical field [0001] The invention relates to the technical field of electric energy storage, in particular to a test and evaluation method of a distributed energy storage system. Background technique [0002] The application of distributed energy storage systems in the power user side is increasingly widespread, and the application scenarios are diversified. However, its small capacity, large quantity, unbalanced distribution, high single-unit access cost, and difficult system operation and management have brought increasingly severe challenges and technical difficulties to the planning and operation of the power grid. [0003] The publication number is CN107769234A, and the name is a multi-point energy storage coordinated distributed power supply adjustment ability evaluation method. The technical solution calculates the load deviation of the regional power grid and the power deviation of the distributed power supply. The short-term power prediction calculates the maxim...
