A comprehensive assessment method for the operation effect of a power grid side energy storage power station

Abstract

The invention discloses a comprehensive assessment method for the operation effect of a power grid side energy storage power station, and the method comprises the steps: constructing an energy storagepower station operation effect assessment index system, and determining a to-be-assessed scheme set; According to the actual operation data of each power station, calculating and extracting evaluation indexes of all schemes in the scheme set to be evaluated of each power station to form an initial decision matrix, and performing standardized processing to obtain a normalized decision matrix; Adopting an analytic hierarchy process to obtain a subjective weight vector of the evaluation index, adopting an entropy weight method to determine an objective weight vector of the evaluation index, andobtaining a comprehensive weight vector of the evaluation index through a game theory combination weighting method; And comprehensively evaluating the operation effect of each power station. The constructed index system has scientificity, applicability and operability, the selected indexes are high in applicability, and calculation is easy; The actual operation effect of the power grid side energystorage power station is comprehensively evaluated from many aspects, and a basis is provided for planning construction, scheduling operation control and the like of a subsequent energy storage project.

Problems solved by technology

[0004] The energy storage power station on the grid side of Zhenjiang has played a major role in the balance of electricity generation and consumption during the summer peak season in Zhenjiang in 2018, and has provided important experience and reference for the construction of energy storage power stations in my country. There is still a lack of comprehensive evaluation of the operation effect. Therefore, it is of great practical significance to conduct a comprehensive evaluation of the actual operation effect of the grid-side energy storage power station from various aspects, and provide reference for the planning and construction, dispatching and operation control of subsequent energy storage projects.
