分布式风光储对中压配电网的影响

Influence of distributed wind-solar-storage system on medium voltage distribution network

分布式风光储的合理接入对提高配电网的经济性与电压稳定性具有重要意义。对风光储接入中压配电网后配电网的稳定性、电能质量和经济性进行分析,通过分析可知,风光储集中接入和分布式接入配电网末端均可有效提高配电网的运行经济性和电压水平。最后,通过某地区实际系统算例验证了所得结论的有效性。

The reasonable access of distributed wind-solar-storage system is of great significance to improve the economy and voltage stability of distribution network.The stability,power quality and economy of distribution network after the wind-solar-storage system is connected to the medium voltage distribution network are analyzed.Through the analysis,it can be seen that both centralized access and distributed access to the end of distribution network can effectively improve the operation economy and voltage level of the distribution network.The validity of the conclusion is verified by a practical system example in a certain area.
