Power system energy storage suitability evaluation method and system

Abstract

The present invention provides a power system energy storage suitability evaluation method and system. The method includes the following steps that: an index evaluation system is constructed; the application scene of an energy storage device is determined; the basic evaluation data of the energy storage device are acquired; each evaluation criterion is evaluated independently; and all the evaluation criteria are evaluated comprehensively. According to the power system energy storage suitability evaluation method and system of the present invention, the two-level index evaluation system is built to evaluate the applicability of the energy storage device to various application scenes; and an evaluation criterion qualitative and index factor quantitative combined mode is adopted, and therefore, subjectivity and objectiveness can be both considered, and the applicability of the energy storage device in a power system can be comprehensively and authentically evaluated.

Description

technical field [0001] The invention relates to the technical field of energy storage performance evaluation, in particular to a method and system for evaluating the applicability of energy storage in a power system. Background technique [0002] In recent years, countries all over the world are vigorously developing various energy storage technologies, and are constantly demonstrating, verifying, promoting and applying them in all aspects of the power system. All kinds of energy storage technologies are in the stage of rapid development and have their own advantages in power system applications, but no energy storage technology can meet all the needs of the power system at the same time. Various energy storage technologies have different performances in terms of energy density, power density, service life, and economic cost. [0003] At present, scholars in the industry and at home and abroad only compare the characteristics of various energy storage technologies from the ...

Problems solved by technology

[0003] At present, scholars in the industry and at home and abroad only compare the characteristics of various energy storage technologies from the aspects of technology or economy, without linking the applicability of energy storage with the application occasions, making no requirements for basic evaluation data, and neither Factors such as energy density, power density, and charge-discharge rate are all reflected in the same index, which makes the evaluation system unclear, the evaluation data is complicated, quantitative analysis is difficult, and the evaluation results are vague, which affects the target groups and potential customers' understanding of various energy storage technologies. Intuitive understanding of the applicability of power systems in different applications
