Abstract: The requirement of electricity in India is increasing at a high rate. Severe energy crisis has forced the world to develop new and alternative methods such as the use of advanced power electronic systems. Therefore most of the utilities utilizes sufficient electricity and transmit the additional power to grid. One of the methods proposed is solar photovoltaic integrated with the battery storage. Here, solar photovoltaic are integrated with battery using a three level Neutral Point Clamped (NPC) Inverter. A three level Neutral Point Clamped Inverter is integrated using two new configurations or techniques-New Configuration i.e., Space Vector Modulation Technique, which generates balanced capacitor voltage under unbalanced DC voltage. Design and theoretical framework of the modulation technique has been proposed. A new control algorithm has been introduced in order to control the power delivery between the solar PV, battery, grid which uses Maximum PowerPoint Tracking (MPPT) technique.
