摘要
为保证光伏并网后电网运行更具可靠性和经济性,对分布式光伏电源并网给配电网电压和网损带来的影响进行研究.建立光伏并网系统模型,理论分析其对配电网网损和电压分布的影响,并通过Matlab/Simulink平台进行仿真,重点分析、对比配电网接入分布式光伏电源后,不同并网位置与接入容量对配电网电压和网损的影响.仿真结果表明,合理选择配置光伏并网的位置与容量能够有效改善电压分布、降低系统网损.
This paper studied the effects of distributed photovoltaic grid connected systems on voltage distribution and power loss in distribution systems to ensure the reliability of grid operation when photovoltaic was connected. A model for photovoltaic grid connected systems was firstly established, and then the influence mechanism of photovoltaic grid connected systems on distribution systems was analyzed. Matlab/Simulink was used to establish a model for distribution systems of IEEE33 bus. This paper also explored the impacts of its allocation and size on voltage distribution and power loss in distribution systems. The simulation results show that scientific selection of the allocation and size of photovoltaic grid-connected systems can effectively improve voltage distribution and reduce power loss.
