Frequency Optimization in Solar PV Systems Using VI-based Synchronous Inverters with ADP Controller

Abstract

This paper proposes an alternate method of opt-mization approach for solar photovoltaic (PV) systems using VI- based synchronous inverters with adaptive dynamic programming controllers. The goal is to enhance the performance of the Grid-connected PV system. A synchronous inverter that is based on VI is used in order to transform the direct current (DC) electricity that is produced by the photovoltaic panels into alternating current (AC) power suitable for use in households or for feeding back into the grid. The adaptive dynamic programming controller is used for the purpose of achieving optimum performance from the inverter and the PV system, taking into account the dynamic behavior of the system and the varying environmental conditions. The proposed approach is evaluated using simulation studies, and the results show that it can significantly improve the performance of the PV system. The approach has the potential to make solar energy more competitive in the market when compared to more traditional electric power sources.
