User-side distributed energy storage evaluation method and system involving optimized operation strategies

Abstract

The invention discloses a user-side distributed energy storage evaluation method and system involving optimized operation strategies. The method includes the following steps that: optimized energy storage operation strategies and operation modes of each stage are determined according to the illumination, load, electricity price data and SOC (state of charge) threshold values of typical days; the net present value and electricity consumption cost of a system are calculated through conversion according to initial capital costs and operation and maintenance costs during the entire life cycle of an energy storage project; and the calculation results of optimized energy storage operation strategies and cost benefits are outputted. According to the user-side distributed energy storage evaluation method and system of the present invention, grid-connected type distributed photovoltaic and energy storage combination is adopted as the research focus of a user-side distributed energy storage application mode, the costs and obtained benefits of the energy storage system are determined accurately in a targeted manner, and a reliable and important basis is provided for the future development prospect of user-side distributed energy storage.

Description

technical field [0001] The invention relates to the technical field of power system analysis, in particular to a value evaluation method and system for user-side distributed energy storage including an optimized operation strategy. Background technique [0002] In recent years, the development of the economy and the improvement of people's living standards have brought new challenges to the stability of power grid operation and power demand. As a core component and one of the key supporting technologies of the Energy Internet, energy storage technology can not only change the time-space coupling characteristics of power generation, transmission, distribution and consumption in traditional power systems, but also greatly improve the flexibility of power supply. It may bring about changes in the way of electricity production and utilization, so as to better restore the commodity attributes of electricity. [0003] The Energy Internet provides a platform for various energy sto...
