Distribution Network Reconfiguration with Wind Turbine Based on Breaking Circle

As a supplement to traditional power supply, wind turbine has a significant impact on the original operating mode of distribution system. To achieve the reconfiguration of distribution network with wind turbine, probability-based scenario analysis is raised to form typical scenarios of wind turbine with consideration of statistical characteristics of wind energy output. By generating the switch state graph of distribution system, network reconfiguration is simplified to the optimization problem of network switch state combination. For model solution, genetic algorithm and the way of "breaking circle" is employed to seek optimal network reconfiguration scheme with wind turbine under mono-scenario and the multiscenario.The experimental results from a 33-node distribution network with wind turbine have shown the efficacy and feasibility of the novel approach.
