光伏接入对配电网电压分布的影响
Influence of PV integration on distribution network voltage
摘要
Abstract
In recent years,the large-scale integration of photovoltaic(PV)power generation into the distribution net-work in Ningxia has altered the network's power flow and the bus node voltages.In order to further examine the impacts of PV integration on the voltage distribution in the distribution network,this article analyzes the voltage fluctuation principles after PV integration and conducts simulation experiments.It finds out that various PV system integration factors-including the method,capacity,and integration location-have impacted the network's voltage distribution.The integration of the PV system with excessive active power output has resulted in voltage limit exceedances at the end of the distribution network.It is found that the penetration rate of the PV system reaches about 50%,offering optimal support for the node voltage of a 35 kV distribution network.Moreover,the closer the PV integration location is to the network's end,the greater its impact on the system voltage.关键词
