Modeling and Performance Analysis of Two Different Inverter Topologies for Integration of 180 Kw Solar Photovoltaic (Spv) System to Distribution Grid at Rubesa

Abstract

Solar photovoltaic system (SPV) is one of the clean and environment friendly renewable energy sources which is deployed by many power utilities and domestic households. The solar photovoltaic system (SPV) exhibits an intermittent nature of power source, its output power never remains constant throughout the day. Thus maximum power point tracking method is implemented to minimize the power variation. For the grid connected SPV system, grid-tied inverter is important component. The nature of output current and voltage depends on the circuit topology of inverter. Thus the behavior of PV array and inverter is analysed by modeling and simulating in MATLAB/Simulink software. Hence this paper presents on modeling and performance analysis of grid-tied sinewave and five-level multilevel inverter with fuzzy logic-based maximum power point tracking using MATLAB/Simulink software. The nature of inverter output voltage and current is analysed and compared for five different performance parameters.
