分布式光伏电源接入对配电网电能质量的影响

Impacts of Distributed Photovoltaic Power Supply Access on Power Quality of the Distribution Network

光伏发电作为具有发展前景的清洁能源之一,随着其发电技术的不断发展,光伏发电并网的容量不断增大,分布式光伏对配电网电能质量的影响日益增强。利用PSCAD建立仿真模型进行仿真计算,分析分布式光伏的接入位置、接入容量等因素对配电网电压质量及谐波的影响规律,并提出电能质量问题相应的改善措施。

With the continuous development of the technology,photovoltaic power generation is continuously increasing as a clean energy source with good development potential.Therefore,the effect of distributed photovohaics to the power quality of distribution networks is increasing.PSCAD is used to establish a simulation model for simulation and calculation.The influence of factors such as access position and access capacity of distributed photovohaics on the voltage quality and harmonics of the distribution network are analyzed,and the corresponding improvement measures for power quality problems are proposed.
