An Island Partition Method Based on Modified Binary PSO for New Distribution Network

As new energy sources are increasingly widely accessed in active distribution networks (ADN).The high intermittency and uncertainty of its new energy power generation pose new challenges to the safe and stable restoration of power supply after the failure of the active distribution network. Therefore, This paper proposes a new method for island partition problem of new distribution networks. A model based on graph theory is established. A modified binary particle swarm optimization is used to find the optimal solution of the island partition problem, and for the purpose of quickly converging, a precoding process is added before the optimization process. An example analysis based on the US PG&E69 node distribution network system is done. The example analysis shows that this paper’s method has good stability and efficiency.
