Abstract

The ever-increasing demand on power system necessitates the deployment of FACTS devices to enhance controllability and also increase power system capability. Conventionally, some FACTS devices are separately used to control the voltage magnitude, whereas some are used to control the power flow on the transmission lines. However, Unified Power Flow Controller (UPFC) has the advantage of being able to simultaneously and independently control the voltage magnitude and the power flow through the transmission lines of a network on which it is connected. This paper presents a Brainstorm Optimization Algorithm (BSOA) based method for optimal placement and sizing of UPFC on standard IEEE 14-bus network. Analysis was conducted based on three scenarios (full loading, moderate loading and at critical loading) in order to demonstrate the effectiveness of the approach. The simulation results indicate that BSOA is robust based on the facts that all the voltage profile that violate ± 5 % tolerance margin of the nominal voltage criteria were kept within the acceptable limit. Moreover, the proposed approach also records significant reduction in the overall real power loss in the whole network.
