“…It can give power transmission lines the boost they need, especially the unified power flow controller (UPFC) type; two converters and two transformers are included, one connected in series with the transmission line and the other in parallel. UPFC controls the flow of actual and reactive power through the transmission line independently by inserting voltage into the transmission line [2]- [4].…”

Transmission line losses are one of the essential topics and issues in power systems research. Several methods and techniques have been used to reduce these losses, and one of these modern techniques is flexible alternating current transmission systems (FACTS). In this paper, one of the most important types of this technology, the unified power flow controller (UPFC), was used to reduce losses in the Iraqi national grid (ING) 400 kV. This paper presents an efficient method for minimizing losses of transmission lines in the ING system (400 kV) 46-bus approach. A particle swarm optimization (PSO)-based optimum proportional-integral (PI) controller with UPFC was proposed to obtain the optimal location of UPFC and optimum parameters of the PI controller to achieve the objective function of the research. MATLAB coded the algorithm. The Newton-Raphson method was employed to perform load flow analysis. The results showed that the best place for UPFC is buses (14-17) named BGE4 (Baghdad)-AMN4 (Baghdad), and the total active power and reactive power losses decreased from 727.4593 to 579.3874 MW and from 5155.9 to 3971.1 MVAR, respectively and also led to voltage regulation.

“…STATCOM is a shunt connected reactive power compensation device it is capable of generating and absorbing the reactive power. [2][3] HPFC is combined compensators where the device is the combination of both series and shunt compensators. HPFC is used to deal with the above problems namely high cost efficiency and also if focuses on grid connection and operating performance.…”

The paper proposes the power flow control in the transmission line using FACTS devices. In the existing system the power flow in the line system is controlled by using STATCOM. In the proposed system we are going to implement the Combined FACTS device. Which is a combination of series and shunt controller like HPFC (Hybrid power flow controller). Comparison of open loop and closed loop are analyzed for fourteen bus system. In the closed loop PI and FOPID are analyzed for both FACTS Devices. The simulation of both open loop and closed loop are done in the Matlab software.
