Active Decentralised Control Approach for Neutral Current Elimination in Smart Grids

Manish Mohandas, Arun Sebastin

Abstract: In a three phase four-wire system, load imbalance and associated neutral currents pose major problems such as over-heating of rotating machines, malfunctioning of control equipment and protection relays, overloading of neutral conductor in the distribution system and transformer core saturation. As such the neutral current has to be eliminated for maintaining the system reliability and for power quality improvement. So this work proposes an active decentralised control scheme for neutral current eliminationby locally providing the necessary compensation using a solar compensatorand thereby to improve system stability. The smart grid modelling and analysis are done by time domain simulations in PSCAD software.

Keywords: Distribution static compensator DSTATCOM, Model predictive controller MPC, power quality PQ, and Voltage-source inverter
