The construction of intelligent power supply systems for rural consumers (microgrids) is a promising concept for the development of the energy infrastructure of agricultural facilities. In the process of designing and operating micro-networks, a large number of technical, organizational and legal issues arise, the correct answer to which affects on the reliability, quality and efficiency of electricity supply to agricultural facilities. The analysis of the documentation regulating these processes is of particular relevance. (Research purpose) The research purpose is in analyzing the documentation regulating the construction and operation of intelligent power supply microgrid systems for rural consumers. (Materials and methods) The article reviews regulatory documents in the field of regulation of the electric power industry, distributed generation facilities, renewable energy sources, and the functioning of retail electricity markets. Authors used the method of system analysis, methods of comparisons and analogies, and expert assessments. (Results and discussion) The article presents the issues of functioning of micro-networks of rural consumers as part of the power system, in retail electricity markets; implementation of technological connection and integration of micro- networks into distribution networks. Authors evaluated the regulatory and technical documents regulating the general technical requirements for the design and operation of micro-networks. Domestic and foreign standards for the connection and parallel operation of micro-networks with distribution networks as part of the power system and special documents on micro-networks has been studied. (Conclusions) The article proposes measures for the development of GOST R based on the European IEC TS 62898-1 «Microgrids», harmonized with the requirements of Russian standards, taking into account the features of the Russian electric power industry and agriculture. The article notes the need to make changes to the Russian network codes to ensure the integration of rural micro-networks. The measures of state support aimed at stimulating the spread of intelligent power supply systems for rural consumers were cited.

The relevance of the work is determined by the need to improve the electrical distribution grids of railways on the basis of digital technologies. The article presents advanced methods of transportation and distribution of electric power in smart power grids of railways based on multi-agent control. The analysis of the power supply system for stationary railroad consumers was performed and advanced ways of their development were defined. These methods should provide increased speed, adaptive determination of restrictions on using electric power equipment, management of mode parameters, sectioning and power flow modes in electrical distribution grids, restoration of power supply after emergency events. The method of adaptive control of transportation and distribution of electric energy in the power supply system of stationary railway consumers is developed based on the hierarchical structure of IEC 61850. This method takes into account the coordination of managing and local controllers in the data exchange environment, the control results and the variable area of responsibility of controllers and their division according to their functional purpose based on the multi-agent approach. The method of power flow control was developed to reduce power losses, increase the capacity of transport channels and ensure the restoration of the normal mode of the electric network by reconfiguring it and controlling active elements based on graph theory. The method takes into account the expected daily load curve, limits on the demand for capacity by active consumers and the possibility of a closed mode of electrical network operation through controlled cross-sections. The simulation results presented on the test circuit have showed the feasibility and efficiency of the proposed approaches.

Today, due to the increase in smart grid and DC appliances implement the use of renewable energy, the power consumption of equipment and appliances can be monitored by smart outlet or smart meter. However, if every devices are installed a meter will be very expensive and lack of flexibility. This work proposes a combination of multi-channel power supply and matrix measurement of electrical meter data management system to increase system built facilitate and promote greater consumption analysis flexibility and benefits. The proposed method includes a programmable logic controller (PLC)based Multi-channel power supply switch circuit (MPSC), measurement control circuit and Zigbee intelligent socket (Smart Outlet) for collecting and controlling the power flow with wireless communication. Three types of wireless metering methods are used to compare cost and metering error rate. The experimental results reveal this work can be an efficient and low-cost metering solution.
