Abstract

The invention provides an active power distribution network distributed energy storage system optimal configuration method and device. A traditional energy storage optimal configuration method and a shared energy storage idea are combined to establish a three-layer planning model of shared energy storage optimal configuration, namely an upper-layer model, a middle-layer model and a lower-layer model, and the model is solved by adopting a method of combining a genetic algorithm and cone programming.

Description

technical field [0001] The present application belongs to the technical field of power distribution system automation, and in particular, relates to an optimal configuration method and device for a distributed energy storage system of an active power distribution network. Background technique [0002] In recent years, with the development and utilization of renewable energy and the construction and development of smart grids, distributed energy resource (DER) has been more and more widely connected to the power distribution system. Compared with flexible loads such as electric vehicles and air conditioners, distributed energy storage can provide higher flexibility to the power system, because it can store energy when the power supply is in excess, and release energy during periods of high demand to relieve network congestion. The application of distributed energy storage systems is increasingly changing the pattern of the entire power supply and demand system. At present, s...
