Expansion Planning Method of Active Distribution Network Considering DG Active Management Strategy

To solve the problem that the active management strategy is not considered in the current active distribution network expansion planning research, we propose a new active distribution network expansion planning method considering active management strategy. Combining active management with distribution network extend planning and DG locating and sizing. Considering the impact of DG active management on the distribution network, the two-layer planning model is used to optimize the line structure of the distribution network and the locating and sizing of the distributed generation. The upper model is optimized by the binary particle swarm optimization algorithm, and the lower model is optimized by the particle swarm optimization algorithm. The analysis of the example shows that the proposed method can reduce the economic cost and improve the reliability of the distribution network.
