Abstract: A solar power plant including a power conversion system and a method of controlling the power conversion system. Implemented in a DC/AC inverter, the plant includes photovoltaic modules (PV modules) arranged in arrays connected to a respective DC/DC converters. A power collecting grid interfaces between the DC/DC converters and the DC/AC inverter. The method includes monitoring the performance of each PV array by adjusting the voltage level of each interface between a PV array and the corresponding DC/DC converter, and includes monitoring the output power of each DC/DC converter as a feedback for the regulating.
