Abstract

The load demand in power systems is increasing exponentially, making it difficult for the existing power system
networks to meet targets due to scarcity of resources. To address this issue, this paper proposes a unified power
flow controller application to meet the increased load demand in the existing power system networks. The proposed
technique uses a Fuzzy Logic Controller (FLC) as an intelligent tool to overcome the limitations of the existing
UPFC controller under varying operating conditions. The UPFC shunt and series controllers based on FLC are
developed as a stand-alone module in PSCAD software. The proposed FLC based UPFC is tested using IEEE-14
bus system with various test cases and compared with the exiting Proportional-Integral (PI) controller based UPFC
to demonstrate its effectiveness. Our results show that the proposed FLC successfully improves the performance
of UPFC by enhancing the active power flow. In addition, it further reduces the reactive power and improves the
voltage profile.
