“…The interconnection of these DGs to the conventional grid is normally achieved by employing power converters. The use of power converters offers vast benefits like optimal operation and flexible control [3]. However, this power electronic interfacing creates a plethora of power quality problems [4 problems in a microgrid are of a large variety such as voltage harmonics, voltage sags, voltage swells, voltage unbalance, current harmonics, reactive power compensation (RPC), current unbalance and circulation of neutral currents, impulse transients, and interruptions [8].…”

Flexible ac transmission systems (FACTSs) and voltage-source converters, with smart dynamic controllers, are emerging as a stabilization and power filtering equipment to improve the power quality. Also, distributed FACTSs play an important role in improving the power factor, energy utilization, enhancing the power quality, and ensuring efficient energy utilization and energy management in grids. This paper presents a literature survey of FACTS technology tools and applications for power quality and efficient utilization of electric system. There are some drawbacks of FACTS devices. These drawbacks can be fulfilled by using new compound, scalable, light weighted and cost effective devices that are distributed-FACTS (D-FACTS). D controllers are distributed version of conventional lumped FACTS controllers and their cost is low due to lower ratings of component and reliability also increases due to redundancy of devices. The Enhanced Power Flow Controller (EPFC) is a D FACTS controller which is distributed version of thyristor controlled series controller. DPFC controllers are used in series at small distance gap at every 5-10 km distance with transmission line to control the power flow. This paper discusses extensive review of the DPFC controller and its application in modern power system era.

“…These result in voltage drop profile, increased network losses, poor network efficiency, instability, and disturbance [10]. Under the pressured situation, one of the efficient ways to save the network from voltage collapse is to lessen the reactive power load or add additional reactive power sources by introducing reactive power sources such as Static Var Compensator (SVC) [11]. The SVC has a positive contact on improving the network voltage profile, improving the power factor, voltage stability, and minimizing power loss.…”

Rising demand for electrical power due to the global technological advancement has brought so many challenges such as instability of voltage, huge power loss, and unstable power factor on the distribution network. This work applied Static Var Compensator (SVC) to the power distribution network of Ado-Ekiti, Nigeria, to study its effect on active power loss reduction and voltage profile improvement of the network. The bus voltage, power, and the current flowing through the selected feeders were measured and recorded accordingly for analysis. Test network parameters like route length, transformer parameters, and maximum power flow were obtained from Benin Electricity Distribution Company, Ado-Ekiti, Nigeria. The distribution network was then modeled and simulated with and without SVC in NEPLAN software environment. The simulation results of the power flow and voltage stability analyses of the network without SVCs showed that some distribution lines were overloaded and that the network parameters were not within the statutory tolerable limits of 0.95 p.u. and 1.05 p.u. nominal voltage. There was 9.73% reduction in the active power loss when SVCs were incorporated into the test network. The voltage stability curve showed an increase in distribution network capacity from an initial steady-state of 150% to 263% of the total active load when the SVCs were incorporated. Hence, the need to normalize the network by applying SVCs to all the buses with very low voltages. This work will assist the power distribution supply companies in making some informed decisions in reducing power losses on their networks.

To ensure energy continuity in the interconnected power systems, production and consumption amounts should be in balance, and that can be possible by providing constant voltage and frequency. Otherwise, undesirable large dynamic oscillations, voltage collapse may occur, and the quality of the electrical energy deteriorates. In this study, the power system of the Denizli Region in the Western Mediterranean Region is modeled using realistic national data. The simulation study is carried out to obtain the voltages, active and reactive powers of buses in the case of no-fault and fault occurrence. Using FACTS (Flexible Alternating Current Transmission Systems) technology such as SVC and STATCOM, the power systems can be controlled, and the carrying capacities can be improved within specified limits. Facts devices are capable of producing and consuming reactive power depending on immediate needs, safe and operating flexibility, and having a high reaction time in the simulation studies. The maximum load limits are increased, and the control of the power system is facilitated. STATCOM provides 31.09 % more achievement with respect to SVC device at energy production and consumption rates for the modeled pilot region. The reliability of the power system has been increased against a voltage collapse, thanks to the SVC and STATCOM controllers. Furthermore, the voltage stability of the generator is also raised, and correspondingly the capacity of the power system enhances. The results are compared to the existing system, and the obtained improvements may be assessed for the enhancement of the interconnected network grid of Turkey.
