The contemporary power distribution system is facing an increase in extreme weather events, cybersecurity threats and even physical threats such as terrorism. Therefore there is a growing interest towards resiliency estimation and improvement. In this paper the resiliency enhancement strategy by means of Distributed Energy Resources and Automated Switches is presented. Resiliency scores are calculated using Analytical Hierarchy Process. The developed algorithm was validated on the modified IEEE 123 node system. It provides the most resiliency feasible network that satisfies the primary goal of serving the critical loads.

The importance of purification of everyday wastes contains in elimination of surfactants (SA) and organic compounds. In this work the results of experimental tests of organic oxidation by ozone, which are amplified by electrical discharges or ultrasound are presented. Circuit diagrams of water purification from surfactants and organic pollutants (OP) are given. Model solutions of sodium lauryl sulfate, as SA, and ethylenediaminetetraacetic acid, as OP are used. The regularities of the influence of pH in the process of electrodischarge and cavitation treatment of OS solutions in the presence of ozone on the quantitative indicators of their destruction were established. The influence of the duration of the treatment process on the persistence of contaminants. The oxidation process was investigated at various concentrations of the initial materials. It has been established that the destruction of surfactants and drugs proceeds better when ozone is combined with the effects of electropulse, at high pH values.

There is a significant risk of instability, which may lead to wide-spread blackout if power system is stressed towards their stability limit under any unexpected serious disturbances. Frequency is a reliable indicator for identification of power system instability. Therefore, under-frequency load shedding technique is used to stable the power system by reduce the load. This article is focused on determining the frequency of UFLS scheme to ensure the optimal sequence of switching off consumers. For this goal it is proposed to use the optimization method. A developed method upgrades the UFLS model for assessment of optimal load capacity and load disconnection sequence during a power system emergency. The simulation results prove that proposed method is an effective approach to improve power system reliability.

An experimental study of partial discharges that occur in a sample of insulation at alternating current voltage and equivalent direct current voltage was carried out. The resulting oscillograms demonstrate the main differences between partial discharges at alternating current and direct current voltage for dry and moistened insulation. It was shown that insulation moistening is more unfavorable for insulation at direct current than at alternating current voltage. The performed studies are aimed at increasing the dielectric strength of the insulation of high voltage direct current transmissions as one of the key components of the Smart Grid.

Paper represents the subtle analytical technique, applicable to the problem of reasonable reduction of Park-Gorev equations, theoretically formulated and sporadically discussed ever since the classical model of electric power system (EPS) has been widely introduced to analyze transient phenomena and steady-state modes of single- and multimachine system. The derived equations of quazi-stationary modes give the correct solutions for synchronous and asynchronous modes of the electrical machines. Analytical approach presents a valuable theoretical basis for eliminating the shortcomings of reduced classical model and helps to represent the EPS components, including machines, lines and loads with regard the true features of physical system.

The paper deals with analysis of induction motor operation when it is fed by two sources – one is the frequency converter, the second is a low voltage DC source like photovoltaic panel or fuel cell connected in a special manner via the neutral point of the motor. In this special schematic solution, the switches of frequency converter are controlled by proper algorithm that allows transmitting the energy to the DC link. In the article, the effect of the additional current components on the motor's performances is estimated. Detailed mathematical description of the motor within such combined converter is given, simulation results are shown. Recommendations regarding the values of components providing the best operation are given as well.

The electricity market, together with its internal and external environment, forms a complex adaptive sociotechnical system, which consists of a large number of heterogeneous in nature elements. This makes it possible to consider the electricity market system as a complex artificially created integrated system. Using the system approach, the decomposition of the electricity market system as a complex integrated system with market, infrastructural and institutional components is performed. The tree of decomposition was constructed, subsystems of the system were identified and their nature was revealed. Flows created in the subsystems were delimited according to the laws and principles on which the subsystem is organized and functioning. The subsystems responsible for construction, functioning and development of the system have been allocated. Their purpose, temporal and spatial organization was determined. Given the complex nature of the system in question, the number of decomposition levels was deliberately limited to a level sufficient to describe composition, structure and organization of the integrated electricity market system (IEMS). The proposed approach to the decomposition of the integrated electricity market system will be used further to analyze the implementation of innovations in the electricity market system.
