【 摘 要 】
Distributed renewable power generation has obvious volatility and randomness. It has different impacts on voltage, power loss, power quality and so on with different integration schemes in distribution network. It could improve the distribution network voltage level and reduce the power loss with reasonable integration scheme. Conversely, if the integration scheme is not reasonable, it will have bad impacts on power loss and voltage level of the distribution network. TO achieve the optimal planning scheme of Distributed renewable power Generation, a optimal planning method has been proposed in this paper. In the method, the minimum power loss of region distribution network as the optimization objective, long-term sequence simulation with wind energy, solar energy and load actual dates for at least one year in a row has been used to get the annual power loss and voltage qualified rate on different integration schemes. A model is verified by an actual case, which is a large-scale distribution network including multiple feeders. It is shown that the feasibility of the integration scheme. Secondly, the operation requirements of Distributed renewable power generation have been proposed based on the simulation analysis of impacts on voltage distribution of Distributed renewable power generation with PQ and PV operation mode. It is shown that appropriate voltage control strategy could be used to enhance voltage qualified rate.
