Abstract

This paper presents a novel concept of Unified Power Quality Conditioner (UPQC). In steady state conditions, the series compensator is in idle mode and the shunt compensator is involved in reactive power compensation. This paper addresses the reactive power compensation capability of both the compensators in steady state conditions. The problem of UPQC placement is formulated as a single objective problem. UPQC allocation in the distribution system is addressed by Sine Cosine Algorithm (SCA) with the objective of minimizing the losses and improving the voltage profile. Suitable Load Flow method is applied to incorporate the complex voltage and reactive power injected by the series and shunt compensator, respectively. The proposed algorithm is tested on standard distribution systems.
