Abstract

The invention discloses a test and evaluation method of a distributed energy storage system, and relates to the technical field of electric power energy storage. The method comprises the following steps: step 1, acquiring output data of the distributed energy storage system; step 2, clustering the output data of the distributed energy storage system by adopting a kmeans clustering algorithm; step3, selecting a working condition performance reference test mode according to a clustering result and carrying out a test; step 4, recording basic parameters of the distributed energy storage system;and step 5, calculating evaluation indexes of the distributed energy storage system; through the first step to the fifth step and the like, the application working condition performance of the distributed energy storage system is evaluated.

Description

technical field [0001] The invention relates to the technical field of electric power storage, in particular to a testing and evaluation method for a distributed energy storage system. Background technique [0002] Distributed energy storage systems are increasingly widely used on the power user side, and the application scenarios are diversified. However, its small capacity, large quantity, uneven distribution, high cost of single-machine access, and difficulties in 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. This technical solution calculates the load deviation of the regional power grid and the power deviation of the distributed power supply. Short-term power forecasting calculates the maximum net l...
