“…Analysis of the annual energy balance of the HRES under consideration, geographically located in the Tomsk region, showed that the use of DESS with the proposed control algorithm provides an increase in energy production by RES installations and, consequently, an increase in energy efficiency by 28% compared to standard HRES construction methods. It should be noted that the value of this indicator largely depends on the energy potential of RES at the location of the power plant, the ratio of installed capacities and technical characteristics of the main power equipment and load, and can reach values up to 60% [36].…”

The urgent task of modern energy is to ensure reliable and efficient power supply to consumers, even those located in remote, far end places. A hybrid energy system with renewable energy sources is a promising way to ensure such a process. A characteristic feature of the modes of such systems, especially with high penetration levels of renewable energy sources, is the presence of ripples in the charge–discharge currents of the batteries used as energy storage devices. Batteries operation with such current fluctuations leads to rapid degradation of its characteristics as well as a reduction in its lifetime. Furthermore, it leads to a decrease in the reliability of the power supply system and an increase in the cost of generated electricity. A significant drawback of hybrid systems built according to well-known standard schemes is the inefficient use of the primary renewable energy, which is especially critical for energy systems located geographically in areas with severe climatic conditions. This article proposes a new construction method and an algorithm for controlling the modes of hybrid energy systems based on a dual-circuit energy storage device, which increases their reliability and energy efficiency. The prominent outcomes of operating modes of a hybrid power plant with a high penetration of renewable sources are presented, which proves that the proposed method of construction and the proposed control algorithm provide reliable and efficient control of the power balance of the hybrid power system in all possible operating conditions. In addition, the overall efficiency of the proposed renewable energy system is increased from 28% to 60% compared to standard hybrid power plants.

For the solar power engineering development it is essential to determine the photovoltaic plant energy indicators by modeling the solar batteries operating modes. To obtain an adequate solar battery model, we need to determine its main parameters on the basis of an equivalent electric circuit. Modeling the solar battery operating mode, it is necessary to take into account the influence of its heating temperature. We propose a combined research algorithm in MS Excel with the installed add-on “Search for a solution” for modeling of solar battery operating mode. We have given the results of modeling the solar battery operating mode where the calculated solar battery maximum power including its heating, satisfactory matches with the experimental data. The research shows that excluding the solar battery heating, the maximum power value and, accordingly, its efficiency are overestimated in comparison with the experimental data. Moreover, the results of modeling excluding its heating do not provide the required accuracy and the modeling mistakes are more than 30% especially at relatively high values of solar radiation. The given model allows to determine the equivalent circuit parameters and determine the solar battery maximum power depending on the considered factors of its heating temperature and the incoming solar energy.

“…At the same time, the use of biogas plants (BGP) in Russia is contained by many factors, including the lack of development in the design methodology, which would take into account not only climatic conditions, but operating modes [1,2,[12][13][14][15][16][17]. When designing a biomass plant, it is important to select the heating power, taking into account the mode of its operation, as well as the choice of design parameters of the installation, depending on the possible cooling degree of the fermented biomass (substrate) in the event of a disruption in the technological process [11,12,[14][15][16][17][18][19].…”

“…In the start-up mode, stable growth of microorganisms in an anaerobic environment is possible with gradual heating of the loaded raw material, no more than 2 0 С per 24 hours, and bringing it to the required fermentation temperature [1,2,13,[17][18][19][20]. In this case, the required power depends on a number of factors:…”

The peculiarity of renewable sources is their replenishment. To ensure energy security and correctly use land resources, it is possible to use biogas plants, which are renewable sources. However, efficient use of these installations turns out to be a difficult task that requires a comprehensive assessment of the parameters of their operation. In the example under consideration, such parameters are: the choice of the power of the heating equipment of the installation and the determination of the temperature stability of operation in case of a violation of the technological process. One of the important results of the study is that the power for heating biomass in the mesophilic mode with continuous and periodic processes is selected according to the start-up mode, and for the thermophilic mode with the periodic process, the power for heating is determined by the start-up mode, and in the continuous process - by the steady-state mode. The study also provides a calculation of thermal stability for reactors of different volumes at different degrees of their filling with biomass, taking into account the operating temperatures of the biogas plant.
