A Novel Micro grid Operation for a Low Voltage Network with Renewable Energy Source

Abstract

This paper present brief description of a Microgrid development project currently in progress. Initially, then Malaysian renewable energy policy is briefly highlighted. The objective  of having Microgrid is discussed. The main components of Microgrid and the technique on how  the Microgrid central controller was developed is also explained.The result from simulation study of Microgrid system in the project is presented to demonstrate the workability of the concept. The modeling and simulation is performed in DIgSILENT and MATLAB/SIMPOWERSYSTEM software.The simulation shows quite promising results. The Microgrid controller managed to control the voltage and frequency in both grid connected and islanding mode as well as maintained them within mandatory operational limit of respective operation code in Malaysia. An active power loss is also significantly reduced.
