Abstract

The invention provides an active distribution network dynamic planning method. The method comprises the following steps: S1, establishing a demand side load power prediction model, a distributed powersupply power prediction model and a charging and discharging model of an energy storage system; S2, establishing an objective function with maximum social comprehensive economic benefits according tothe demand side load power prediction model, the distributed power supply power prediction model and the charging and discharging model of the energy storage system; S3, planning an energy storage system of the active power distribution network by adopting a chaotic particle swarm hierarchical optimization algorithm, and obtaining the optimal position and power of each energy storage system; andS4, obtaining a charging and discharging strategy of each energy storage system according to the optimal position and power of each energy storage system. The economical efficiency, reliability and stability of the power distribution network are comprehensively considered, and the optimization effect of demand side management and energy storage batteries on the active power distribution network isconsidered. And the stability and the reliability of the power distribution network are considered while the maximization of economic benefits of operators is ensured.

Description

technical field [0001] The invention relates to the technical field of active distribution network dynamic planning, in particular to a dynamic planning method for active distribution network. Background technique [0002] With the opening of a new round of power system reform in my country, reforms in terms of power sales and transmission and distribution prices will have a profound impact on power plants, power grids and power users. Various types of distributed power sources such as photovoltaics, wind energy, and hydrogen energy, energy storage systems, demand-side response loads, and flexible loads and other controllable equipment are more and more used in distribution networks. Due to distributed power sources, energy storage systems, and The uncertainty of multiple factors such as demand-side response load makes distribution network planning need to deal with multiple factors, such as the comprehensive utilization of multiple resources, the mutual coordination of mult...
