This work is aimed at the analysis and justification of the possibility to use renewable energy sources (RES) for budget organizations on the Volgograd region example. Research is being conducted all over the world, its purpose is the search for the most effective non-traditional renewable energy sources, the use of which will allow the transition to resource-saving energy. Since the potential of application in various power systems is practically unlimited, the analysis of the RES implementation in the budget sector organizations taking into account the natural features of the Volgograd region possibility currently appears to be an urgent task requiring a comprehensive study. Traditional power supply systems used in budget organizations are characterized by relatively small initial investments, high annual fuel consumption and the cost of maintaining systems, while systems based on nontraditional and renewable energy are characterized by high initial investments, but also high resource savings and low operating costs. For budgetary organizations, the most pressing issue is the saving of allocated funds and optimization of current costs, in connection with which the issue of developing the most effective not only in technical but also in economic terms RES, the introduction of which is consistent with the existing energy system of the organization, becomes particularly relevant. To date, the organizations of the budget sector practically do not use RES, which is mainly due to the ratio of prices for equipment and energy, as well as due to the unresolved number of technological and organizational problem. Keywords -renewable energy sources, fuel and energy resources, energy saving and energy efficiency, budget organizations2nd International Scientific Conference on 'Competitive, Sustainable and Safe Development of the Regional Economy' (CSSDRE 2019)

Purpose: The purpose of this work is reviewing the concept of « smart manufacturing» as part of the development of the concept «Industry 4.0».Methodology/Approaches: An example of the application of intelligent technologies in an enterprise is presented. The distinctive characteristics of « smart manufacturing» are revealed. The statistical characteristics of the digitalization index of business in Russia and other countries are given. It's proved that the digitalization level of Russian companies is still at a rather low level and isn't ready for the implementation of «smart manufacturing». The advantages and disadvantages of smart technologies are shown.Conclusions: A smart manufacturing approach has many benefits, including long-term savings, increased efficiency and productivity. The main disadvantages of «smart technologies» are the high initial investments and the technological complexity of automated systems. The prospects, problems and economic effects of the introduction of digital innovations, such as: revenue growth, cost reduction, lower labor costs for middle managers, increased investment in fixed assets were identified. Thus, we can conclude that «smart manufacturing» completely changes the vector of development of production as a whole and is aimed at creating a more interconnected and flexible production environment.

The purpose of this work is to develop an automated system for making decisions on energy quality management, as well as diagnostics and management of electrical equipment. The creation of an intelligent automated system for managing the technical assets

В данной работе приводится обзор алгоритмов и методик расчёта эксплуатационных переходных режимов систем электроснабжения. Переходный режим является следствием наличия на предприятии потребителей с резкопеременной нагрузкой, а также использования генерирующих объектов малой энергетики. На сегодняшний день крупные промышленные предприятия вводят в эксплуатацию или уже используют собственные объекты генерации, работающие на базе возобновляемых источников энергии. В связи с чем, возникает необходимость расчёта этого вида режима работы в ходе проектирования и эксплуатации энергосистемы промышленного предприятия.

The ever-increasing trend of renewable energy sources (RES) in energy systems of various levels has increased uncertainty in their operation and management. The vulnerability of RES to unforeseen changes in meteorological conditions requires additional resources to support, which are energy storage systems (ESS). However, existing ETSs have limited capacity to meet all the requirements of a modern enterprise energy system. Thus, the hybridization of multiple ETSs to form a composite ETS is a potential solution to this problem. As a flexible energy source, energy storage has many potential applications for integration into renewable energy generation, transmission and distribution networks. This paper analyzes the prospects for hybrid energy storage applications and summarizes the latest experience in terms of the maturity of these technologies, efficiency, scale, lifetime, cost and applications, taking into account their impact on the entire power system, including generation, transmission, distribution and utilization. The challenges of large-scale applications of energy storage in power systems are presented in terms of technical and economic considerations.
