Research on Simulation Method for Typical Scenes of Microgrid (Group) Access to Distribution Network

Microgrids are attracting attention since they can provide effective solutions for centralized management of DG. Firstly, the grid-connected, isolated and switching operation strategies of master-slave microgrid are studied, and an improved SPLL structure based on flexible handover is proposed. Secondly, on these basis, this paper studies the simulation method for typical scenes of microgrid (group) access to distribution network, moreover proposes a method to divide the scenes by self-powered ratio, and builds the related network topology. Finally, examples are given to simulate the operation mode of the microgrid (group) in different scenes to analyze the operational characteristics of the microgrid (group) access to grid, and the related operation strategy are verified.
