摘要

光伏电站的大量安装会影响配电系统的稳定性。由于来自这些可再生但间歇性能源的潮流的动态变化，光伏接入点的电压会发生变化。这种电压变化会对光伏并网的配电网的稳定性产生广泛的影响。本文对该电站1年(装机容量1.1 MWp)运行情况、电能流向和电压变化进行了分析。通过仿真软件给出光伏并网后的电压变化评估和潮流评估结果。

Analyses of power quality and voltage variation of photovoltaic power plant connected into 22 kV public grid

Stability of distribution system can be influenced by numerous of installed photovoltaic power plants (PVs). Voltage variations are caused in the connection point of PV due to dynamic variability of power flow from these renewable, but intermittent energy sources. This voltage variation can have wide-spread impact to stability of distribution network, where is PV connected. This paper deals with analysis of one year of PV operation (installed capacity of 1.1 MWp), electric energy flows and voltage variation. By simulation software there will be presented results of voltage variation evaluations and load flow evaluations due to PV's operation into primary distribution network.
