Design and Study the Effectiveness of Smart Grid PV System

Abstract

Sustainable energy sources are required to meet the electricity demand and overcome the threat of energy security. Renewable energy comes forward to solve the above problem. Though there are several sources of renewable energy, solar energy is the largest source all over the world. The developments of grid connected configuration are urgently required to meet the future energy demand. There are many technological issues to utilize PV energy in smart grid system. The improved quality charge controller, inverter and their control circuit needs to implement grid connected PV system. For this reason an algorithm has been developed that makes the circuit easy, cost effective and good performance with 96.26% efficiency. Microcontroller based grid connected inverter and control circuit have been developed. The inverter circuit sense feedback from grid. After processing the signal in microcontroller it generate different controlling signal, operation modes and synchronization with grid. The inverter also shows better performance with 88. 16% efficiency. Finally, cost analysis has been performed to implement the grid connected PV system. To justify the economic viability the feasibility study has been performed with 10kwp grid connected PV system for commercial building. The stability analysis has also been performed. The above achievement indicates that the potentiality of smart grid PV system may be the key solution to meet future energy demand and pollution free environment.
