Technical constraints of integrating net energy metering from the Malaysian perspective

Abstract

This paper evaluates the technical issues due to net metering from the Malaysian distribution network perspective. Simulations of Malaysian distribution network with net metering implementation for residential consumers were carried out in DigSILENT PowerFactory. The simulation results demonstrate that net metering at high capacity can cause power quality issues to the distribution network such as voltage rise, fault level increment, and contribution to harmonic distortions. The case studies signify the severity of power quality issues with increasing penetration of the solar photovoltaic. Mitigation measures for the technical issues and proposed sizing were also discussed to ensure the solar PV does not violate any permissible boundaries of the grid. © 2018 IEEE.
