Abstract: Growing environmental concerns and extinction of fossil fuels have shifted the focus on renewable energy resources. Among these alternatives, solar Photovoltaic (PV) energy has been looked upon as the most viable resource and hence it has resulted in proliferation of PV systems integrated to the grid. In addition to all the cherished benefits of PV power as a renewable source, large scale grid connection has led to unprecedented challenges that are being faced by utilities. One of the most serious issues with greater percentage of PV generation is that as these do not participate in grid frequency or voltage regulation, even a small perturbation in frequency or voltage may result in a disaster leading to total blackout. A novel control algorithm has been proposed in this work which offers the advantages of inertia & damping and enables the inverter to regulate the voltage and frequency. Simulated results are obtained in MATLAB/Simulink platform that shows the inverter capability to respond effectively for the grid side fluctuations.
