Optimal Design of Integration of Intelligent, Adaptive Solar (PV) Power Generator with Grid for Domestic Energy Management System

This paper introduces a novel system based on integration of solar power generator with grid for optimal utilization of energy by minimizing the power drawn from grid. A prototype grid integrated PV system comprising of PV module (2*75Wp), battery bank (12V, 2*80Ah) as an energy storage device and an intelligent, adaptive inverter (300W) has been developed and successfully implemented at site. A grid quality AC power, has been obtained with a low (≪ 5%) total harmonic distortion (THD) sine wave output. A micro grid network concept introduced in the system has resulted in a saving of 50% or even more grid power.
