The electric power industry development mean increases the electric grids flexibility through the use of various devices type (FACTS) controlled by means of power electronics and being an element of the Smart Grid. This type of device includes a phaseshifting transformer (PST), which redistributes power flows in the branches of electrical networks. In connection with the relevance of this topic, new technical solutions appear that implement similar functions, which entails the need for a comparative analysis of such developments in order to optimize the energy characteristics of this kind of equipment. The aim of the work is to develop schematic version of the PST made according to the "star" scheme and analyze its operation in typical modes. During the study, the energy characteristics of the device were determined. The possibility of reducing the typical power of the phase-shifting device due to the use of capacitive compensation is analyzed.

The restoration and development of Iraq's electric power industry is planned to be carried out on the basis of the concept of intelligent electric networks (smart grid). To implement this concept, it is necessary to create integrated digital models of electrical networks. Such models can be implemented on the basis of methods and tools for modeling electric power systems in phase coordinates. The report presents the results of modeling normal and emergency modes of distribution electric networks of 11 kV.

Subject. This article deals with the issues relating to improving integrated reporting in terms of dovetailing strategic objectives with capital changes. Objectives. The article aims to develop a system of indicators for disclosure of capital types in integrated reporting of electricity generating companies, as well as recommendations aimed at implementing the fundamental concepts and guiding principles of integrated reporting. Methods. For the study, we used the methods of analysis and synthesis, comparison, generalization, and abstraction. As a case study, we conduct a comparative analysis of the disclosure of six types of capital by the largest electricity generating companies, namely PAO Inter RAO, AO Rosenergoatom and PAO RusHydro. Results. The article formulates proposals for disclosure of capital information to address such a lack of accountability as a contradiction to the principle of coherence. It proposes a system of indicators (core and additional) for disclosure of six types of capital by electricity generating companies. Conclusions. A significant reporting problem is the lack of correlation between key strategic objectives and capital changes. The formulated recommendations for disclosure of capital information can help solve this problem, and increase the attractiveness of the integrated report for capital providers.

Currently the issues of reliability and efficiency assessment of the operation and dispatch control of the Unified Energy System of Russia remain unreported and require the attention of the scientific community, electric power industry stakeholders, as well as federal and regional regulatory bodies. The paper studies the structure, mechanisms of interaction between the operational dispatch control participants and the electric power industry, regulatory legal acts, as well as the practice of operational dispatch control of the Unified Energy System of Russia and the electric power industry of foreign states. The existing system for assessing the reliability and efficiency of the operation and dispatch control of the Unified Energy System of Russia is considered. The study employs such methods as analysis, synthesis, generalization, abstraction, comparative and logical methods. The paper highlights the impossibility of unambiguous perception by all subjects of the electric power industry as a justification for technical solutions, argumentation of their own actions and in other business processes, justification of the position of ensuring reliability, due to the absence of a clearly developed regulatory framework in the field of reliability (generally accepted apparatus and terminological certainty). The paper substantiates the need for monitoring and assessing the reliability and efficiency of operational dispatch control in the electric power industry. The problems of monitoring and evaluating operational dispatch control in the electric power industry are considered. The practical result of the work is suggested drafted organizational structure for monitoring the reliability and efficiency of operational dispatch control in the power industry.

Reform Period

The privatization of the generating assets of the Russian electric power industry during its reform did not solve one of the main tasks related to attracting private investment. In the post-reform period, there was a constant redistribution of property, primarily in domestic wholesale and territorial generating companies. The specifics of such redistribution, leading to additional significant risks of lost profits for investors, were not considered. They were revealed through a comparative analysis of the composition of the main shareholders of these companies in the post-reform period, mainly based on the results of 2009 and 2019. The following main features of the redistribution of property have been determined: its permanent redistribution; the growing presence of the state in the competitive segment of energy production; increased concentration of ownership; growth in the number of offshore foreign companies; insignificant share in the share capital of institutional investors and individuals.
