Reduction of transmission line loss by using Interline Power Flow Controllers

This paper deals with improvement the transmission line loss by using Interline Power Flow Controller (IPFC). The IPFC is a novel FACTS device which can control power flow in power systems. The IPFC consists of multi-series converters. The power flow through the line can be regulated by controlling both magnitudes and angles of the series voltages injected by an IPFC. This paper used differential evolution to determine the control parameters on an IPFC. The proposed method is tested on a sample multi-machine system.
