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.

W artykule omawia się zagadnienie lokalizacji nowobudowanych stacji transformatorowo - rozdzielczych 110 kV/SN na terenie miast i aglomeracji miejskich w warunkach rynku energii elektrycznej w kraju. W ekonomice elektroenergetyki miejskiej problem jest bardzo istotny ze względu na uwzględnienie w modelu rozwoju sieci elektroenergetycznych kosztów gruntu, które w dotychczasowych pracach były pomijane. Koszt gruntu należy uwzględnić, w badaniach gdyż decyduje on o rodzaju rozwiązania stacji 110 kV/SN, sieci 110 kV i sieci średniego napięcia. Omawia się modele optymalnej lokalizacji miejskiej stacji 110 kV/SN oraz algorytmy rozwiązywania problemu różnymi metodami. Omawia się wyniki badań przeprowadzone w sieci elektroenergetycznej Warszawy.

The problem of localization of newly built 110 kV/middle voltage distribution transformer substations in the area of towns and urban agglomerations in conditions of electrical energy market in the country have been discussed in the paper. The problem is very important in urban electrical energy economy because of taking into account the ground costs in the model of network development, which had been neglected in previous works. The ground cost must be considered in the investigations, since it decides about the lay out of 110 kV/middle voltage substations, 110 kV grid and middle voltage network. Models of optimal localization of a 110 kV/middle voltage substation and algorithms of solving the problem by various methods have been described. Results of investigations carried on in Warsaw electrical power network have been presented.
