Cross Subsidization

As scientific community as businessmen discuss the problem of cross-subsidization in the electric power industry. This problem has long remained relevant. The main topic of economic discussions is fairness and validity of the rules for the tariff formation in the electric power industry. The different tariffs allow reducing the financial burden of some consumers and shifting it to others. The aim of the issue is to develop the main vectors of solving problems and government regulation measures. They are expected to level the negative economic effects of cross-subsidization. The purpose of the study is revealed through solving the following problems: a) to determine the socio-economic nature of cross-subsidization and regulatory problems at the current stage of development; b) to study the experience of foreign countries in cross-subsidization policies; review public policy mechanisms related to cross-subsidization. The subject of the issue is economic relations between different economic participants and their interests arising in the process of cross-subsidization policy. The results of the issue are the development of the main directions of the transformation of the state regulation of the energy complex in terms of reducing the negative effects of cross-subsidies. The scope of application of the obtained results is determined by the possibilities of developing and implementing a balanced state policy that takes into account the interests of all participants in economic processes, eliminating the creation of social tension in society that supports the growth of the well-being of the population. The following general scientific and special methods were chosen as scientific tools for conducting this study: content analysis method, system analysis method, retrospective analysis method, statistical survey methods. The information base of the study was the analytical development of the materials of the Federal Antimonopoly Service, the Federal State Statistics Service, regulatory acts of the Russian Federation governing the development of the electric power complex. The basis of the presented study was the basic definitions of cross-subsidies, methods of reducing the negative consequences of cross-subsidies, principles and approaches of state regulation of the electric power complex.

Abstract One of the most essential tasks for a number of systems of the automatic controls in the autonomous electric power systems of the water transport is accurate calculation of variable harmonic components in the non-sinusoidal signal. In the autonomous electric power systems operating with full semiconductor capacity, the forms of line currents and voltages are greatly distorted, and generator devices generate voltage with inconsistent frequency, phase and amplitude. It makes calculation of harmonic composition of the distorted signals be a non-trivial task. The present paper provides a mathematical set for solution of the outlined problem including the realization in the discrete form. The simplicity and efficiency of the system proposed make possible to perform its practical realization with the help of cheap FPGA. The test of the developed system has been performed in the medium Matlab.

Reliability Assessments

Electric power complexes today rightfully belong to the category of complex systems that become integral structural elements of the environment. Any electric power complex created by engineers has to satisfy the corresponding needs of a person, because this is what it is created for. From this point of view, the electric power complex should be considered endowed with appropriate consumer properties, which must show stability during the period of its operation, determined by the reliability indicators, which for the electric power complex must be supplemented by the corresponding safety indicators. It is these indicators that make it possible to conclude about the possibility of manifestation of the electric power complex during the operation of its consumer properties in full and without a threat to people and to the environment, that is, they make it possible to make a decision about the possibility and feasibility of operating this electric power complex. The analysis of the essence of the concept of probability as a tool to overcome the incompleteness and inaccuracy of information about the events under study, along with various concepts (interpretations) of probability from the point of view of their theoretical status and practical application in the problems of calculating the reliability and safety indicators of electric power complexes. Analyzed the classical, statistical and axiomatic concepts of probability, revealed the features of each of these concepts, conditions and reservations regarding their application in engineering practice. Reveals the reasons for the discrepancy between the reliability indicators, calculated at the design stage of devices on the basis of reference data on the failure rate of individual components, indicators that are observed during the operation of these devices, as well as the need to be careful with the processing of observation results in cases where such that differ significantly from the majority. It is noted that the limitations associated with statistical probability can be to a greater or lesser extent leveled by using the concept of hyper-random events, but the widespread implementation of this concept is constrained by the lack of an appropriate experimental database. On the basis of the analysis carried out, urgent tasks are formulated related to increasing the efficiency of calculating the reliability and safety indicators of electric power complexes.
