Transmission Grid Power Quality: Unbalance Factor Forecast by a Novel Three-Phase Power Flow

Abstract

This paper aims at investigating the impact of the increasing demand for electricity on the power quality of the transmission networks. In particular, investigations on the transmission network structure as a source of voltage unbalance are made by performing numerical simulations. All the simulations are carried out by means of the MCA method, and by means of a novel three-phase power flow algorithm named as PFPD_3P. Moreover, proposals and discussions on possible power quality mitigation strategies on the transmission networks are presented (i.e., synchronous compensators installations and/or network reinforcements).
