| Abstract: | Based on the features of simple alternating current circuits, a concept of reactive power margin is proposed and the node where distribution system reactive power compensator is installed is determined by the ordering of reactive power margins of nodes. After the confirmation of compensating node, optimized reactive power planning is implemented by evolutionary programming method. IEEE 33-bus and IEEE 69-bus system show that the reactive power sources can be rationally configured, the search space of GA can be greatly reduced, the voltage quality of distribution network also can be improved, and the reliability and economy of reactive power planning can be realized by the proposed method as well. |
