Abstract

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.
