“…The Static Var compensator (SVC) is used to maintain the voltage in transitional regimes [5], the basic structure (Figure 4) of this controller is the association of: a. TCR (Thyristor controlled reactor) consists of a reactor placed in series with the thyristor valve, the value is continuously variable according to the firing angle of the thyristors. b. TSC (Thyristor swithed capacitor) consists of power capacitor controlled by thyristors connected in parallel to the network through a coupling transformer.…”

In recent years, applications of facts systems have been developed for the compensation of active and reactive power. Facts systems are electronics devices that are connected to the wind farm. This paper presents the impacts of some of these devices on the stability of a wind farm, especially D-STATCOM, Static Var Compensator and Fuzzy SVC controller. First, a presentation of D-STATCOM, SVC, then fuzzy logic controller. In simulation study, the D-STATCOM ensures the stability of the voltage and current at the point of connection with the electrical grid. Finally, Comparing the SVC to the F-SVC simulations, we notice that the F-SVC is more performed than SVC for the compensation of the active and reactive power.

“…Transient stability is taken into consideration in this paper since it has the ability to maintain and synchronise the acceleration of a machine when it is subjected to transient disturbance. The transient stability of a multi-machine system [7] can be maintained and improved by installing a Flexible AC Transmission Systems (FACTS) device [8,9]. FACTS is a device that is effective in controlling power flow, damping power system oscillations and improving the controllability and transfer capability of a power network.…”

“…A Simulink system is configured in terms of a block diagram which is easy to build as it provides a drag-drop method to build a model in block diagram and the simulation results are displayed perfectly [8]. In this paper, a Simulink model is developed to improve the multi-machine system by using an SSSC device as it is widely used for research work and in the field of power systems [9].…”

<span lang="EN-US">Transient stability in power system is vital to be addressed due to large disturbances that could damage the system such as load changes and voltage increases. This paper presents a multi-machine transient stability using the Static Synchronous Series Compensator (SSSC). SSSC is a device that is connected in series with the power transmission line and produces controllable voltage which contribute to a better performance in the power system stability. As a result, this research has observed a comparison of the synchronization of a three-phase system during single-phase faults before and after installing the SSSC device. In addition, this research investigates the ability of three different types of controllers i.e. Proportional Integral (PI), Proportional Integral Derivation (PID), and Generic controllers to be added to the SSSC improve the transient stability as it cannot operate by itself. This is because the improvement is too small and not able to achieve the desired output. The task presented is to improve the synchronization of the system and time taken for the voltage to stabilize due to the fault. The simulation result shows that the SSSC with an additional controller can improve the stability of a multi-machine power system in a single phase fault.</span>

The current rapid growth in IoT technology facilitates the effortless implementation of bidirectional remote monitoring and control system implementation in homes and buildings. We have modeled an actual non-intrusive PnP sequential SVC prototype hardware and wireless FLC automation software design on a real single phase home appliances system as load modeling. In addition, we have also designed a novel Unidirectional MOSFET Switched Capasitor model (UniMosSC) which enables us to reduce the hardware cost and increase the life span of SVC due it uses minimum switching devices. The system we have designed is able to correct the power factor at the root of the problem at each appliance. Due to complexity of appliance clustering and overlapping clusters, we implemented fuzziness in the system for more reliability in computations. The system could be used in homes or buildings resulting in electricity bill reduction, saving dollars and cents.
