Abstract The use of renewable energy sources (RES) and storage batteries (SB) in decentralized power systems is a cost-effective way to supply power to consumers. In this case, storage batteries are one of the most important system components. The significance of storage batteries is conditioned by a stabilizing effect obtained at generation from RES that are defined by stochastic oscillating functions. However, it is worth noting that storage batteries also improve the cost-effectiveness of such systems by reducing consumption of diesel fuel. This is particularly noticeable at night when load is the least and the use of diesel generators is inefficient. One of the most important points is the determination of potential internal processes of aging and breakdowns that occur in storage batteries during operation. The use of a tested model for categorization of storage batteries according to the operating conditions makes it possible to take account of these factors at the stage of a system design. The paper presents a detailed analysis of decentralized power supply system Verkhnyaya Amga. The focus is made on the cost-effectiveness of a combined use of RES with storage batteries, annual saving of diesel fuel, operating parameters. The research reveals hidden problems that represent various uncertainties that affect greatly the economic and operation parameters of the system.

The article describes the principles of creation, management and economics of power complexes based on renewable energy sources for decentralized power supply. The introduction of energy complexes based on renewable energy sources can compete with the centralized power supply of the regions by increasing energy security and reducing the risks of major accidents and disasters. Long-term contracts for the electricity supply can be a reliable and economical insurance in case of rising fuel prices in the long term.

The study presents a brief description and problems of power supply of the Khabarovsk territory. The problems and prospects of the development of renewable energy sources, in particular in the Khabarovsk territory, are considered. There are three main approaches that exist in the scientific community for comparing energy objects. The first approach is based on comparing the technical indicators of power facilities, the second on calculating the normalized cost of electricity, and the third is based on monetizing the environmental and climatic consequences of power facilities. During the study, it was found that these approaches differ in the number of indicators included in the calculation of the cost of electricity. In accordance with the selected approaches, evaluation of economic efficiency of three operating power plants of the Khabarovsk territory – coal, diesel and solar – was carried out, monetized estimates of the full cost of three alternatives for the production of electricity in the region were given, taking into account the environmental component. The analysis made it possible to conclude that under the current market conditions, renewable energy sources are most profitable in decentralized areas, and quantitative evaluations have shown that with the introduction of payments for carbon monoxide emissions, renewable energy sources become an economically effective way of organizing energy supply in the region, including in the regions with centralized power supply.

Pooling different renewable energy sources (hydrogen, solar, wind, geothermal, etc.) enables developing a standalone energy micro-grid. The energy flows from these various sources are neither constant nor equivalent. Therefore, control and balancing mechanisms should be established for optimal energy utilization through an intelligent system based on interconnected microcontrollers networked with sensors. Our contribution addresses this issue by proposing an original architecture of an intelligent and distributed control system based on a sensor network and a strategy to share the electric power through the micro-grid. In our work we consider a micro-grid powered by sources of wind turbine, pv panels and battery which energy flows are controlled and balanced through our system depending on power demand of the loads. Alternating Current (AC) bus and Direct Current (DC) bus are tied together by an inverter. A set of microcontroller-sensor-actuators (which we named S.A.D for Sensor/Actuator Device) are deployed at strategic points in the micro-grid providing constantly data from power generated and consumed, equipment health and status. A control algorithm developed in relation to a network control strategy is implemented by combining the performance different microcontroller boards. Relying on existing literature works, a review of solution approaches to the challenging problem, of the power flows balancing between the different energy sources and storage batteries embedding appropriate IoT technologies and exploiting energy big-data platforms, is presented

Purpose. To determine the features of operation of photovoltaic stations as а supplementary source of electricity for non-traction consumers of railway power grids. The research methodology is based on modern methods of computational mathematics, statistics and information analysis using modern computer technology. Findings. The authors analyze the current prerequisites for the use of electricity obtained from non-traditional sources (photovoltaic stations) to supply non-traction consumers of railway power grids. The nature of the intensity of solar radiation was clarified due to meteorological observations for 2018, recorded using a SMIR pyranometer from KIRP & ZONEN, which is specially designed to record the flow of solar energy falling on a flat surface from the sun and sky in the wavelength range from 300 to 3000 nanometers (Nm), which has an intelligent interface, in the city of Vasylivka, Zaporizhia region with an interval of minutes. The total number of values was about 25,000. The data obtained are as follows: the lowest intensity of solar radiation during 2018 was 400 W / m2, and the highest - 1000 W / m2. The calculation of the choice of photovoltaic panels type PV-MLV 250 NS with a maximum power of 250 W for the completion of a specific photovoltaic station for installation in the specified region. The authors conclude that in order to provide reliable energy supply to non-traction consumers of railway power grids during the day from autonomous solar power plants, the latter must be provided with electricity (storage batteries) in quantities exceeding the required load by about 1.7 times. The originality is that the use of renewable energy sources in the power supply systems of non-traction consumers of railway transport, in particular photovoltaic installations, is proposed. Practical implications. Introduction of photovoltaic stations as a supplementary source of electricity for non-traction consumers of railway power grids in order to minimize electricity costs. Keywords: renewable energy sources, quality of electric energy, photovoltaic plant, power supply networks of railway transport, non-traction consumers of railway electric networks, electricity production, solar radiation intensity, storage batteries.
