Smart Grid Integration for Power Quality in Grid System

Abstract: The increase penetration of renewable energy, use of electronic load in to the electric grid which involves a challenge regarding the power quality issues and energy management. These penetrations will increase harmonic distortion, frequent switching of load will result in flicker. This paper presents an implementation of power control scheme & communication scheme in smart grid integration for maintaining power quality and for managing energy in the grid system. The integration of smart grid is equipped with voltage source converter attached to the renewable sources, conventional energy generators and storage systems. The primary power control scheme is the voltage source converters operated in current controlled mode with hysteresis control in order to maintain power quality requirements in distributed system .The secondary scheme involves the use of a distributed communication architecture based on Experimental Physics and Industrial Control system (EPICS) to manage all the information generated in grid system and help in a smart grid for managing energy norms. Test results are presented to demonstrate the effectiveness of the control and the communication architecture used for maintaining power quality in smart grid integration.
