Extraction method of typical working condition curve of energy storage system and evaluation system thereof

Abstract

The invention provides an extraction method of a typical working condition curve of an energy storage system and an evaluation system thereof. The method comprises the following steps: reading operation data of a new energy power generation system and the energy storage system; determining or reading the charge and discharge power data of the energy storage system within a collection time, and forming a charge and discharge power matrix; obtaining a characteristic charge and discharge power value vector at a k moment according to interval distribution properties of a power value of the energy storage system; determining a typical power value of the energy storage system at the k moment; eliminating the power of the energy storage system with relatively small amplitude, and determining the typical power value of the energy storage system at the k moment; integrating the typical power value, and determining the typical power value of the energy storage system at the k moment; analyzing and integrating the typical power values at all moments to obtain the typical working condition curve of the energy storage system; and evaluating the typical working condition curve. By adoption of the extraction method provided by the invention, the operation reliability and stability of the new energy and energy storage hybrid power generation system are improved.

Description

technical field [0001] The invention relates to the fields of large-scale energy storage technology, energy internet and data mining, in particular to a method for extracting a typical working condition curve of an energy storage system and an evaluation system thereof.
