摘要
分布式电源在配电网的接入规模越来越大,但分布式电源出力的不确定性对配电网电压质量带来了严重影响。在对分布式光伏和分布式风电出力特性分析的基础上,建立了分布式电源接入配电网的仿真模型,仿真了分布式电源不同接入位置和不同接入容量下的配电网,并从电压谐波含量、电压波动两方面分析了不同接入情况下的配电网电压质量,获得了分布式电源接入对配电网电压质量的影响规律。
The access scale of distributed power supply in thedistribution network is increasing,but the uncertainty of the output of distributed power supply has a serious impact on the voltage quality of distribution network.Based on the analysis of distributed photovoltaic and distributed wind power output characteristics,a simulation model of distributed power supply connected to distribution network is established.The power distribution networks with different access locations and different access capacities of the distributed power supply are simulated.The voltage quality of the distribution network under different access conditions is analyzed from two aspects of voltage harmonic content and voltage fluctuation.The influence law of distributed power supply access on the voltage quality of distribution network is obtained.
