Development Of Solar Power Based Net-Metering System For Domestic Prosumers

With the increase of human population of the world and the rapid growth of the global economic, the demand of the energy resources especially electricity faced a tremendous increase. Countries across the globe are looking for some alternative sources of energy to cope up the depletion of fossil fuels. These alternative sources also help in minimizing the impact of climate change. Power generation through renewable sources like rooftop solar is considered as the best alternative. Solar has some drawbacks. Net-Metering is the solution for solving those drawbacks. Net metering is a policy by the virtue of which unconsumed energy is fed into the distribution network and is utilized by the nearby consumers, connected to the same distribution network. This paper, focuses on Grid connected solar photovoltaic electric system. The paper aims at modelling high performance Three Phase Single Stage Grid Connected Inverter and Bi-Directional energy meter. So as to achieve maximum output from the photovoltaic array, MPPT Tracking is connected. The conversion from DC output of photovoltaic array is done to AC so that it is fed into the grid, a IGBT based inverter is used which converts from DC to AC power and a Bi-Directional energy meter designed to measure the net energy. The Simulation model is developed in MATLAB Simulink and Proteus and the results are presented in the paper.
