Project Summary

Renewable energy provides a way of generating clean energy. Micro-grid is defined as the combination of distributed generation, electric energy storage and loads. Micro-grids thus offer a power system to integrate power generated from renewable sources and provide features like increased reliability, flexibility, cost effective and efficient energy. The parallel operation of small energy sources delivering energy by using inverters as an interface gives modularity to the system and provides extra reliability and redundancy. In this project parallel inverters are integrated by reducing circulating currents and regulating frequency and voltages. It is achieved by using droop control method, the proposed system will integrate parallel sources. The validity of the design will be verified through computer simulation tools and hardware prototype.

Project Objectives
