Demand for renewable energy sources has increased due to the limited nature of fossil fuel reserves, which lead to carbon emissions into the atmosphere. Presently, solar and wind power stand out as the most widely adopted renewable energy options for integration into the power grid. Solar energy, specifically harnessed through photovoltaic systems, has become increasingly affordable and is characterized by its cleanliness and lack of pollution. Consequently, photovoltaic power generation has garnered significant attention, particularly in developing nations. Within the realm of photovoltaic energy systems, there exist two primary categories: grid- connected systems and stand-alone systems. Among these, grid-connected photovoltaic systems offer an effective means to incorporate solar energy into the existing electrical grid infrastructure. A pivotal component within these grid-connected photovoltaic systems is the inverter, which can exert a substantial influence on the system's overall performance. This influence extends to factors such. as. total harmonic. Distortion. (THD) and efficiency.Over the past decade, the concept of multilevel inverters has gained popularity in. the. field. of. renewable energy applications. In the context of this dissertation, various topologies of grid-tied. photovoltaic. systems. are. thoroughly examined to demonstrate the potential of such systems. Additionally, the dissertation attempts to conduct simulations of grid-connected photovoltaic systems, incorporating Maximum Power Point Tracking(MPPT) techniques in conjunction with multilevel inverters, using MATLAB/SIMULINK software.
