The goal of multi-criteria decision making (MCDM) is to select the most appropriate of the alternatives by evaluating many conflicting criteria together. MCDM methods are widely available in the literature and have been used in various energy problems. The key problems studied in electrical power systems in recent years have included voltage instability and voltage collapse. Different flexible alternating current transmission systems (FACTS) equipment has been used for this purpose for decades, increasing voltage stability while enhancing system efficiency, reliability and quality of supply, and offering environmental benefits. Finding the best locations for these devices in terms of voltage stability in actual electrical networks poses a serious problem. Many criteria should be considered when determining the most suitable location for the controller. The aim of this paper is to provide a comparative analysis of MCDM techniques to be used for optimal location of a static VAR compensator (SVC) device in terms of voltage stability. The ideal location can be determined by means of sorting according to priority criteria. The proposed approach was carried out using the Power System Analysis Toolbox (PSAT) in MATLAB in the IEEE 14-bus test system. Using ten different MCDM methods, the most appropriate locations were compared among themselves and a single ranking list was obtained, integrated with the Borda count method, which is a data fusion technique. The application results showed that the methods used are consistent among themselves. It was revealed that the integrated model was an appropriate method that could be used for optimal location selection, providing reliable and satisfactory results to power system planners.

Among the FACTS device, the distributed power flow controller (DPFC) is a superior device. This can be evaluated after eliminating the dc capacitor between shunt and series convertors of the unified power flow controller (UPFC) and placing a number of low rating single phase type distributed series convertors in the line instant of using single large rating three phase series convertors as in the UPFC. The power flow through this dc capacitor as in the UPFC now takes place through the transmission line at a third harmonic frequency in the DPFC. The DPFC uses the D-FACTS that allows the replacement of a large three-phase converter as in the UPFC by several small-size series convertors present in the DPFC. The redundancy of several series convertors increases the system’s reliability of the power system. Also, there is no requirement for high voltage isolation as series convertors of the DPFC are hanging as well as single-phase types. Consequently, the DPFC system has a lower cost than the UPFC system. In this paper, the equivalent ABCD parameters of the latest FACTS device DPFC have been formulated with the help of an equivalent circuit model of the DPFC at the fundamental frequency component. Further, the optimal location in the transmission line and maximum efficiency of the DPFC along with Thyristor Controlled Series Compensator (TCSC), Static Synchronous Shunt Compensator (STATCOM) and UPFC FACTS devices have been investigated using an iteration program developed in MATLAB under steady-state conditions. The results obtained depict that the DPFC when placed slightly off-center at 0.33 fraction distance from the sending end comes up with higher performance. Whereas, when the TCSC, STATCOM and UPFC are placed at 0.16, 0.2815, 0.32 fraction distances from sending end respectively give their best performance.

W artykule przeanalizowano wpływ sterowników FACTS (PST oraz IPC) na pracę połączenia transgranicznego Polska-Niemcy. Stwierdzono, że przesuwnik fazowy PST spełnia podstawowe wymagania i tylko w niewielkim stopniu wpływa na automatykę zabezpieczeniową. Jego rozbudowa do układu międzyfazowego sterownika mocy IPC umożliwiłaby dodatkowo odcięcie się od zakłóceń pochodzących z niemieckiego systemu, jednakże wymagałaby istotnych zmian w automatyce zabezpieczeniowej.

Unplanned energy flow from Germany via Poland to the Czech Republic caused overheating of transmission lines in the west of our country. In order to prevent the necessity to switch off these lines, phase shift transformers (PST) were placed on the border. However, the German system is highly saturated with wind electricity and therefore difficult to steer, which makes it a source of interference for neighbouring countries. The article analyses the impact of flexible AC transmission system (FACTS) drivers on the operation of the Poland-Germany cross-border electrical connection. It was found that the PST meets the basic requirements and has only a slight influence on the protection automatics. Expanding it to the interphase power controller (IPC) would additionally cut off the interference from the German system, however, it would require profound changes in the protection automatics.

The FACTS (Flexible AC Transmission System) devices have been considered as excellent controllers in a power system for better reliability and transmission capacity on a long-term and cost-effective basis. The static synchronous series compensator (SSSC) is one of robust FACTS devices that can control the flow of power in AC lines. In this paper, modelling and simulation of active and reactive power flow control in transmission lines and voltage control using SSSC with adaptive neuro-fuzzy logic is proposed. The mathematical model of SSSC in power flow is also proposed. The results show the ability of SSSC to control the flow of power in the AC lines of power system within line voltage limitations.

This paper presents the application of Flexible Alternating Current Transmission System (FACTS) devices based on heuristic algorithms in power systems. The work proposes the Autonomous Groups Particle Swarm Optimization (AGPSO) approach fort he optimal placement and sizing of the Static Var Compensator (SVC) to minimize thetotal active power losses in transmission lines. A comparative study is conducted with other heuristic optimization algorithms such as Particle Swarm Optimization (PSO), Time-varying Acceleration Coefficients PSO (TACPSO), Improved PSO (IPSO), Modified PSO(MPSO), and Moth-Flam Optimization (MFO) algorithms to confirm the efficacy of the proposed algorithm. Computer simulations have been carried out on MATLAB with the MATPOWER additional package to evaluate the performance of the AGPSO algorithm on the IEEE 14 and 30 bus systems. The simulation results show that the proposed algorith moffers the best performance among all algorithms with the lowest active power losses and the highest convergence rate.

The hybridization of a recently suggested Harris hawk’s optimizer (HHO) with the traditional particle swarm optimization (PSO) has been proposed in this paper. The velocity function update in each iteration of the PSO technique has been adopted to avoid being trapped into local search space with HHO. The performance of the proposed Integrated HHO-PSO (IHHOPSO) is evaluated using 23 benchmark functions and compared with the novel algorithms and hybrid versions of the neighbouring standard algorithms. Statistical analysis with the proposed algorithm is presented, and the effectiveness is shown in the comparison of grey wolf optimization (GWO), Harris hawks optimizer (HHO), barnacles matting optimization (BMO) and hybrid GWO-PSO algorithms. The comparison in convergence characters with the considered set of optimization methods also presented along with the boxplot. The proposed algorithm is further validated via an emerging engineering case study of controller parameter tuning of power system stability enhancement problem. The considered case study tunes the parameters of STATCOM and power system stabilizers (PSS) connected in a sample power network with the proposed IHHOPSO algorithm. A multi-objective function has been considered and different operating conditions has been investigated in this papers which recommends proposed algorithm in an effective damping of power network oscillations.

The generalized interline power-flow controller (GIPFC) is a voltage-source controller (VSC)-based flexible ac transmission system (FACTS) controller that can independently regularize the power-flow over each transmission line of a multiline system. This paper presents a modeling and performance analysis of GIPFC based on 48-pulsed voltage-source converters. This paper deals with a cascaded multilevel converter model, which is a 48-pulse (three levels) source converter. The voltage source converter described in this paper is a harmonic neutralized, 48-pulse GTO converter. The GIPFC controller is based on d-q orthogonal coordinates. The algorithm is verified using simulations in MATLAB/Simulink environment. Comparisons between Unified Power Flow Controller (UPFC) and GIPFC are also included.

In this paper, an expert system-based fault detection and classification scheme is developed for a laboratory prototype model of TCSC compensated long transmission line (thyristor controlled series compensator). The equivalent model of laboratory prototype system is simulated in MATLAB Simulink. An expert system based on fuzzy logic is developed by using threephase voltage and current signals from single end measurements. Obtained voltage and current signals are pre-processed with Discrete Fourier Transform (DFT) to obtain the fundamental component of these signals. Further zero sequence current and obtained fundamental voltage and current signals are used to develop a fuzzy inference system (FIS) for shunt fault detection and classification task. There are three different FISs developed for three individual phases of the transmission system and one FIS is developed for zero sequence current signal, which provides ground involvement information. The combined binary output of the developed four FISs provides fault classification. The performance of the developed FISs is rigorously tested with the variation of different fault parameters, and different location of the TCSC. The simulated results indicate that the proposed scheme performance is reliable in its zone of protection.

Nowadays, in modern power systems there is a tendency to build more and more dispersed energy sources, to increase their transmission abilities and to increase their size. Parallel to these actions, the requirements regarding the quality of the delivered energy and system reliability are also increased. These changes required the new solutions to system control in both static and dynamic states of work to be implemented. The paper includes the analysis of the application of the multiphase Matrix Converter (MC) to the development of the phase shifting device. The analysis was performed not only on the basis of the simulation, but also on the basis of the waveforms obtained from the real life model constructed in the laboratory. The relationships between the device control algorithms and the properties of the built on their basis phase shifting device were thoroughly investigated. Some of the described properties of the MC are not only connected to its ability to influence active power flow in the power line, but also to its impact on reactive power transmission. For three developed control procedures, the reactive power flow control was investigated for MC working as a voltage source inverter on inductive load. The capabilities of alternative control procedures and short device reaction times can be useful not only for power flow control, but also during system dynamic states for example to fast dumping of the system oscillations. The research is the continuation of the previously published work, and its next step will include the solution to the MC commutation problems and the implementation of the MC based shifting device to the already build model of the multi-node power system.

This paper presents an analysis of the application of a multi-phase matrix converter (PM) based device as a phase shifter (PS). The analysis was conducted using simulation techniques and measurements performed on a six-phase converter model built in a laboratory. Three basic control schemes and their relation to PM properties are presented. In addition to the phase shifter’s ability to change active power transfer, the device’s impact on reactive power transmission was also shown in the paper. Newly assessed PM properties permit the construction of a PS with higher power system control capacity than with currently available devices. Capabilities of various variants of PM control and fast rate of response of the PS based on it, will undoubtedly be useful in the control of dynamic states of the power system operation (postdisturbance states), e.g. for rapid elimination of generator oscillations or power flow adjustment. This study is an extension of the phase shifter concept presented in previous years, and the continuation assumes the construction of a shifter model for use in an already developed at Cracow University of Technology power system model.
