Abstract

The invention relates to a power distribution network energy storage system configuration method based on active management and cost-benefit analysis, and the method comprises the following steps: S1, an active management system is established for actively managing a power distribution network, and a cost-benefit analysis system is also established and comprises an energy storage configuration model; S2, a power distribution system module reads time series data of annual load and photovoltaic power generation output, records a real-time SVR/OLTC running state and transmits to the cost-benefit analysis system and an EMS control module; S3, the EMS module compares the present voltage level data with a set voltage index and transmits charge-discharge power information to an energy storage system module to control the present voltage level in a normal range; and S4, the cost-benefit analysis system performs cost-benefit calculation on the energy storage system and optimizes the energy storage capacity configuration. According to the invention, the power distribution network active management system is established to perform the active management of the power distribution network; and the energy storage cost-benefit analysis system can accurately describe the energy storage configuration model.

Description

technical field [0001] The invention relates to the field of energy storage system planning in an active distribution network, in particular to a distribution network energy storage system configuration method based on active management and cost-benefit analysis. Background technique [0002] Distributed generation (DG) grid-connected power generation is considered to be one of the important research directions of the power industry in the 21st century. DG will be connected to the distribution network on a large scale in the future. However, the increase of DG penetration rate will also bring a series of impacts on distribution network voltage, power quality and dispatching operation. With its fast power adjustment and the characteristics of both supply and storage capabilities, the energy storage system has played a huge role in smoothing intermittent energy power fluctuations, peak shaving and valley filling, improving voltage quality, and providing backup power. It is an...
