Droop Control Technique for Parallel Inverters Operation in Lighting Smart Grids Applications

Abstract

In last few years, many countries are investing in smart grid technologies due to their potential benefits in improving energy efficiency, reliability, and sustainability, to meet demand of electrical power of booming population by integrating renewable energy and reducing the greenhouse gas emission. A Smart-Grid is an advanced, intellectual, localized, small scale grid which can be disconnected from centralized grid and operates autonomously but the integration the renewable energy generations can result in a substantial voltage or frequency deviation in MGs. To enable zero net-energy consumption and optimal power management for future micro-grids, several key technologies and strategies need to be implemented. Therefore, this paper introduces an enhanced finite control set model droop control. Voltage and frequency can be regulated by controlling the active power injection into the system. The effectiveness of the proposed Droop Control is verified by simulation results in the Matlab/Simulink environment. A detailed investigation of voltage regulation of a residential Micro-Grid (MG) is given to demonstrate the effectiveness of the proposed approach.
