Abstract
This paper applies a dynamical electrical array reconfiguration (EAR) strategy on the photovoltaic (PV) generator of a grid-connected PV system based on a plant-oriented configuration, in order to improve its energy production when the operating
conditions of the solar panels are different. The EAR strategy is carried out by inserting a controllable switching matrix between the PV generator and the central inverter, which allows the electrical
reconnection of the available PV modules. As a result, the PV system exhibits a self-capacity for real-time adaptation to the
PV generator external operating conditions and improves the energy extraction of the system. Experimental results are provided
to validate the proposed approach.
