摘要
为了降低分布式光伏接入对配电网的影响,本文从单个光伏和多个光伏两个角度对配电网中光伏接入引起的电压变化进行理论分析,并在PSCAD中建立仿真模型对理论分析的结果进行验证,结果表明,对于单个光伏接入的配电网,接入位置越接近线路末端,电压提升幅度越明显,对于多个光伏接入的配电网,应考虑采用均匀分散接入方式,以减小光伏接入带来的影响。
In order to reduce the impact of distributed photovoltaic access on the distribution network,this paper theoretically analyzes the voltage changes caused by photovoltaic access in the distribution network from the perspective of single photovoltaic and multiple photovoltaic,and establishes a simulation model in PSCAD to verify the results of the theoretical analysis.The results show that for a single photovoltaic access distribution network,the closer the access location is to the end of the line,the more obvious the voltage rise,For the distribution network with multiple photovoltaic access,the uniform and decentralized access mode should be considered to reduce the impact of photovoltaic access.
