Design and analysis of grid connected photovoltaic inverter under normal and fault conditions

As there is a power shortage across any country, usage of renewable energy sources is being encouraged nowadays. This energy produced has to be properly synchronized with the grid to ensure safety and energy continuity. In this paper, a step by step procedure for designing a MPPT algorithm based photovoltaic (PV) generation system is presented. Moreover, the standard procedure for grid interconnection of inverter is discussed. The developed system feeds a common load, as the micro grid systems feeds the local loads. The system takes care of all the specified guidelines while feeding the load and is compared with the IEC 61727 standards, which discuss the current harmonic limit for a grid tie inverter.
