Abstract: Along with the connection of numerous flexible resources such as distributed generation and electric vehicles (EVs) to distribution networks, higher requirements are raised on system security and reliability. A distribution network reconfiguration method based on distributed generation and EV cluster scheduling is thus proposed to improve the system security and reliability. With consideration of voltage deviation, the network topology structure is reconstructed by taking the failure loss cost of power grid as an economic index to measure the power network reliability. Firstly, a distribution network reconfiguration model is established to minimize the comprehensive cost by taking the switching state of power lines, the charging and discharging state and power of EVs as decision variables. Then, the symbiotic search algorithm is used to solve the reconfiguration model. Finally, the effectiveness of the proposed method is verified via simulation of a distribution system.

Key words: distribution network reconfiguration, distributed generation, electric vehicle cluster scheduling, symbiotic organism search algorithm
