“…The root causes of the irregular GBAO EPS operation are as follows:  Due to GBAO specific geographic locality, the electrical networks have radial circuit with a large electric ETLlength with voltage 35 кV about 100 km resulting in profound voltage reduction at ETL endpoints;  As power plants are of low power, the power network loss occurs while regulating the voltage at these power plants generators. Thus, the relevance of the work is specified by the research conducted and solutions searched to reduce the risk of power failures and, also with the possibility of reactive power regulation using compensating devices optimal location as well as to meet the technical and economic requirements taking into account the current power plants capacity [1]- [3].…”

“…The original modification of the full Newton method with optimal step selection was developed in the software used for calculating EPS modes set, taking into account equation peculiarities of nodes voltage given in the rectangular coordinates. The nodes of appropriate linguistic variable with voltage "below normal" is circled with a blue color and these nodes are: 3,4,9,10,11,12,37,38,40,42,43,44. Total nodes are 12.…”

“…The fuzzy logic field of application is broadened in the repair planning and electrical failures, load predicting and electrical failures detection. Traditional mathematical models are based on the knowledge containing set of rules defining corresponding actions for given system modes [1]- [3]. If the information is fuzzy, the expert systems cannot operate well with this data.…”

Effective electricity use can be an option which enables to achieve significant economy while generating and transmitting of electricity. One of the most important things is to improve the electricity quality through reactive power correction up to optimum values. The current article presents the solution to compensate the reactive power in the distribution networks, in GornoBadakhshan Autonomous Oblast (GBAO) with the use of the advanced technologies based on the data collection within real time. The article describes the methodology of fuzzy logic application and bio-heuristic algorithms for the suggested solution effectiveness to be determined. Fuzzy logic application to specify the node priority for compensating devices based on the linguistic matrix power loss and voltage gives the possibility to the expert to take appropriate solutions for compensating devices installation location to be determined. The appropriate (correct) determination of the compensating devices installation location in the electric power system ensures the effective regulation of the reactive power with the least economic costs. Optimization problems related to the active power loss minimization are solved as well as the cost minimization with compensating devices to ensure the values tan(φ) not exceeding 0.35 through reducing multi-objective problem to the single-objective one using linear convolution.

“…Since the introduction of optimal multiple energy carrier systems, numerous studies have explored modifying and further developing them to enhance their reliability and control [11][12][13][14]. The concept of the energy hub has been applied across different regions and fields of study [15][16][17]. Planning of energy hub networks and their operation has been the focus of several research projects [18][19][20][21], especially for aspects pertaining to economics and the environment [22][23][24].…”

: The concept of energy hubs has grown in prominence as a part of future energy systems, driven by the spread of Distributed Energy Resources (DERs) and the inception of the smart grid. This paper systematically reviews 200 articles about energy hubs, published from 2007 to 2017, and summarizes them based on their modeling approach, planning and operation, economic and environmental considerations, and energy hub applications. The common applications of energy hubs are considered, such as distributed energy resources, the consideration of Plug-in Hybrid Electric Vehicles (PHEVs), and the hydrogen economy. This paper examines modeling approaches towards energy hubs, including storage and its network models; it mentions some of the optimization strategies used to tackle the efficient operation and control of energy hubs. The novelty of this work lies in the classification of research papers related to energy hubs, the development of a generic framework for modeling these multiple energy flow carriers with storage and network considerations, and the provision of solution techniques in line with energy hub optimization.
