More Information
Summary:The invention discloses a DG-included power distribution network planning method based on a Voronoi graph. A DG-included power distribution network chance constraint planning model is built according to the power grid operation condition, wherein the model includes components such as investment and operation cost, and planning is constrained in a flexible constraint mode. For the load point distribution issue, a greedy algorithm based on the Voronoi graph is put forward and approaches the optimal value by seeking the local minimum value in every iteration. The DG-included power distribution network planning method adopts a genetic algorithm, codes the position of a transformer substation before optimization and testifies the meeting condition of chance constraint in every optimizing process.
