Abstract—The Flexible AC Transmission System (FACTS) technology is a new advanced solution that increases the reliability and provides more flexibility, controllability, and stability of a power system. The Unified Power Flow Controller (UPFC), as the most versatile FACTS device for regulating power flow, is able to control respectively transmission line real power, reactive power, and node vol...

the interline power flow controller (ipfc) is a concept of the facts controller for series compensation which can inject a voltage with controllable magnitude and phase angle among multi lines. this paper proposes a novel ipfc-based damping neuro-control scheme using pso for damping oscil la t i o ns in a power system to improve power system stability. the add i tion of a supplementary controll...

Wind power is the fastest growing renewable source of electrical energy hence it has become necessary to address problems associated with maintaining a stable electric power system. The wind generated power is always fluctuating due to its time varying nature and causing stability problem. Unified Power Flow Controller (UPFC) is used to control the power flow in the transmission systems by cont...

In this paper, a dynamic model of Unified Power Flow Controller (UPFC) is developed to improve the power transfer capability (PTC) through the transmission line. Improvement of the bus voltages profiles along with the reduction of total power losses is also intended with UPFC’s presence. The UPFC shunt and series controllers are developed based on Fuzzy Logic (FL) which has been designed as a s...
