With the gradual mature of renewable energy resource such as wind power generation and solar power, and with advance and development of the power market step by step, distribution network is not only related to the fluctuation of the load and renewable energy resource output, but also need considering the influence of the future power market on distribution network with renewable energy resource. Under the background of electricity market reform, the power demand response for consumer is focused more and more. And it will bring positive impact on the distribution network planning if load could be cut off or interrupted. Therefore, a distribution reactive power planning method considering demand response is presented in this paper. The method considers output fluctuation of renewable energy resource and interruptible load under power market background. The influence of demand response is considered in the reactive power planning. The example analysis proved that the proposed reactive power planning of distribution network with renewable energy resource considering demand response is feasible and it is more economic and practical than traditional method.
