Cascaded Multilevel Inverter for PV-Active Power Filter Combination into the Grid-Tied Solar System

Abstract

The presence of non-linear loads (electronic power converter...) into the grid generally affects the electric power quality. This latter presents a fundamental factor in the grid consumers' performance. In addition, nowadays, the photovoltaic (PV) energy integration spreads for residential and commercial applications. These PV systems impose the use of power inverters to liaise with the electric grid. In this context, this power disorder fix is included in the list of PV inverter functions. That is recommended to guarantee better equipment performance. A MATLAB/Simulink simulation shows the electrical behavior of the whole model.
