The and 2010, up to the current level of 1000 MWp. Due to the power is tranfered from the photovoltaic power plant by means unfavourable properties of photovoltaic cells, PPPs affect of a cable terminal through a 3x22 AXEKVCE cable 130 m adversely the distribution network to which they are connected. long to a compact 0.4/22 kV transformer station equipped with The present paper describes results of analysis of PPP operation a 1250 kVA transformer and further on through a 22 kV line to with focus on the dynamics of changes in the power supplied and a 22/110 kV substation. on compliance with technical requirements for the connection of sources to the distribution system.
