“… where is the inter-area power oscillation in the transmission line 23 . The purpose of using intelligent algorithms is to minimise the defined objective functions according to the range of variation in the control variables 24 , and minimising each objective function equals the maximum damping of the system and the minimum number of small-signal oscillations.…”

The static synchronous series compensator (SSSC) can add a series reactance to the transmission line, and when it is fed using auxiliary signals, it can participate in damping inter-area oscillations by changing the series reactance. In this paper, the effect of the SSSC on small-signal stability is investigated. The design of a controller for damping oscillations is designed and discussed. Moreover, using the firefly and the harmony search algorithms, the optimal parameters controlling SSSC are addressed. The effectiveness of these two algorithms and the rate of SSSC participation in damping inter-area oscillation are also discussed. MATLAB software was used to analyse the models and to perform simulations in the time domain. The simulation results on the sample system, in two areas, indicated the optimal accuracy and precision of the proposed controller.

“…It is important to take into consideration designing static var compensators to maximize the reduction of power quality issues. According to the journal of Naderipour, et al (2020) [7] regarding the optimal designing of static var compensator to improve the acquired voltage of a power system, that a static var compensator is an appropriate solution to reduce the power quality on power systems caused by electric arc furnaces. Electric arc furnaces are one of the major causes of problems in power quality but with the help of static var compensators, harmonic currents are reduced significantly and ultimately improved the voltage profile of a power system.…”

Electricity in the present time is pretty much a necessity hence the need for more supply to cover every household. Due to the increase in electric power demand, there is a need for long-distance, large power transmission lines. Given the increase in power distribution, the new transmission lines still need to meet quality standards. Considering that developing a new transmission line is costly and time-consuming, an alternative solution is required. This research aims to show the effects of a Static Var Compensator (SVC) on how it can improve the voltage of a transmission system. An SVC is a set of electrical devices that provide fast-acting reactive power on high-voltage electricity transmission networks. Using MATLAB/Simulink, we will design and simulate a transmission system with an SVC under different cases of varying loads. The data gathered will then be compared to see the effect of the SVC on a transmission system. Results should show that there should be a voltage improvement when an SVC is present in the transmission system.

“…Among many nonlinear loads, AC electric arc furnace (EAF) is the most complicated and most random pollution source. The voltage fluctuation, harmonic, three-phase unbalance and other power quality problems caused by EAF have been the focus of research [1][2][3][4]. For voltage problems of EAFs, in the initial stage of melting, the unstable arc combustion causes power fluctuations and then causes the arc voltage fluctuations.…”

Three-phase AC electric arc furnace (EAF) is a typical non-linear load, causing many power quality problems. Most of the researches on the voltage problems of EAF mainly focus on the voltage fluctuation, and less on the transient voltage problems caused by EAF short circuit and open circuit. In this paper, the relationship between voltage and current of EAF is obtained by combining hyperbolic function and exponential function, then the white noise and chaotic circuit are added to establish the EAF model which is suitable for the study of voltage fluctuation and transient voltage. This paper analyzes the causes of the transient voltage problem of the EAF, calculates the short-circuit current, reactive impact and the influence on voltage at the point of common coupling (PCC) in the three-phase short-circuit of the EAF, and compares the calculation results with the simulation results to prove the accuracy of this model. The results show that the reactive impact of three-phase short circuit is about twice as much as that of normal operation of EAF, resulting in about 30% voltage sag at the PCC, which is very unfavorable to the power grid. This paper provides reference for transient power quality evaluation and dynamic reactive power compensation of EAF.
