<p>The increase in load demand has a negative impact on power system quality, reliability, and stability. Transporting reactive power from the generating side to the distribution side reduces the transmission line’s capacity to deliver active power to loads. In conventional power systems, during faults or sudden loads, the load flow changes and causes extra voltage drop. Reactive power compensation at the load side can improve voltage quality at distribution busbars, but the conventional compensation method doesn’t offer the required flexibility. With the development of the power electronics industry, flexible alternating current transmission system (FACTS) devices have been introduced. There are many categories for FACTS controllers, including series, shunt, and hybrid, which can exhibit dynamic operating characteristics. In this paper, two types of FACTS devices (STATCOM and fixed capacitor-thyristor-controlled reactors (FCTCR)) have been used to improve voltage profile in a part of Iraq’s high voltage power system during unusual operating conditions, such as sudden loads and the absence generation. Load flow calculations were conducted to determine the critical bus, and then the performance of the FACTS devices was investigated during heavy loading when the devices were connected separately to the critical bus. The voltage drop in the bus was 1.58%, which reduced to 0.78% with STATCOM and 0.96% with FCTCR.</p>

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.

The Static Synchronous Compensator (STATCOM) is one of the most currently used Flexible Alternating Current Transmission System (FACTS) devices utilized to control the voltage and power flow. This work proposed an application of the STATCOM devices to maintain the voltages within the specified limits and enhancing voltage deviation, as well as reducing the apparent power losses. The STATCOM device has been chosen using the minimum possible size of the reactive power injected or absorbed by the STATCOM devices while satisfying the stability limits. A Genetic Algorithm (GA) is one of the Evolutionary Computation Techniques used to optimally determine the best locations and sizes of the STATCOM devices to be installed. The proposed approach has been examined and tested first on a 14-bus IEEE test system; the results obtained encouraged us to implement the same approach on the 27-bus Iraqi National (400kV) Super High Voltage Grid (INSHVG) System (part of the Iraqi power network), with different power system load conditions for all season in the year such as summer, winter, spring, and autumn to find the impact of the best location and size of each STATCOM device. A computer program, written in MatLab environment, was developed to represent the proposed method.
