Grid Integration of Hybrid Generation Scheme for Optimal Switching Pattern Based Asymmetrical Multilevel Inverter

Presently, (RES) Renewable Energy Systems are getting more widely preferred with accumulate of energy demand and concern for the environmental impact around the world. The Hybrid Generation Scheme (HGS) exerts fuel cell (FC) and photovoltaic (PV) sources are the main energy generation sources. Integration of hybrid generation system to grid has favorable advantages and integrated with the help of DC/DC-converter because of maintains dc link voltage as a constant and interfacing to grid by using inverter model. Basic need of multilevel inverters has gained more attention in the area of distribution of energy and control due to its advantages in high power applications with low harmonics and also good quality of output voltage. This paper proposes a three-phase Asymmetrical Multilevel Inverter (AMLI) is more suitable converter for hybrid generation scheme, and also compared to the formal multilevel inverter contains need more switches for getting higher voltage levels, gate drive circuit and area of the requirement reduces. The Proposing AMLI produces 7-15V levels by using 9 switches for this more levels THD goes to reduces. The proposed scheme is comprehensively evaluated with improved performance of AMLI using Matlab/Simulink Package.
