Utilization of optimization strategies in photovoltaic integrated multiltvel inverters for enhancing power quality

Abstract

In recent periods, the design of utility network is highly crucial in power system due to large changes in the approaches of the power supply. The primary duty is to provide better power quality of power to the distributed consumers. Thus, the utilities are always emphasing on advanced methodologies to supply good power quality (PQ) to its consumers. Further, as there is wide requirement of energy demand, it is necessary to incorporate different distributed supplies to the system. Therefore, in this paper, a photovoltaic (PV) combined multilevel inverter (MLI) for enhancing the PQ in the utility network. For operation of the multilevel inverter a newly developed optimization technique is employed. The proposed method is related with other existing methods. The PV system is also operated using a modified version of the conventional maximum power point technique (MPPT). The overall performance of the system is verified and analysed using MATLAB/Simulink software.
