As the impacts of distributed generators (DGs) on distribution systems are significant, this paper proposes a particle swarm-based optimization technique to define an optimal coordination of DGs, an under load tap changer (ULTC) including substation and feeder capacitors for volt/VAr control. The objective for the coordination is considered in the view point of the distribution system operators as...
This paper presents the optimal dispatch for the under load tap changer (ULTC) of a substation transformer, substation capacitors, and feeder capacitors for volt/VAr control in a distribution system. Three objectives of interest in the problem consist of energy loss, total capacitor kVAr to be switched on, and total number of daily switching operations of the ULTC and all capacitors. The optimization...
