Abstract

An intermediate photovoltaic power system (160 kVA, 380 V three-phase) that could be used as a stand-alone energy power supply and as an AC back up system has been designed. For this purpose it was necessary to use self-commuted inverters; a suitable power control logic was also required in order to compensate for reactive power and optimize power flow from the photovoltaic array to the AC power line. Good agreement between theoretical studies and simulation results confirms the validity of the proposed power control logic
