Network reconfiguration and operation optimisation of distribution system with flexible DC device

Abstract

In this study, a comprehensive reconfiguration and operation optimisation of distribution system with flexible DC device (FDD) is discussed. The structures of distribution network with FDD are illustrated and the exact operating of FDD set‐points are discussed which realised power flow control and loop closing operation of distribution system. Then, the non‐linear combinational optimisation models of reconfiguration and operation optimisation with FDD are established considering different objectives and constraints. In order to solve the complicated optimisation problems, improved particle swarm algorithm and sequential AC/DC power flow method are used. Results show that the FDD have stronger ability to promote the performance of distribution system with power flow optimal adjusting and cooperation with traditional switch.
