“…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].…”

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.

“…Для сельскохозяйственных потребителей развитие автономной системы электроснабжения важно в случае отсутствия централизованной системы электроснабжения. В этом случае использование фотоэлектрических установок (ФЭУ) позволит замещать дорогостоящие органические топлива для автономных источников и снизить затраты на потребляемую электроэнергию [11].…”

The article cites the need for a reliable and economical power supply to rural consumers. At the same time, it is important to develop distributed generation, including on the basis of renewable sources, using solar and wind energy to reduce costs. The necessity of choosing solar panels with optimal parameters, taking into account the influence of external factors, is shown. To determine the actual generated power of solar batteries, the concept of "power loss during the conversion of the solar radiation flux into electrical power" is introduced. It has been established that insufficient studies of the regime parameters of photocells, in particular, the temperature of its heating and the corresponding change in efficiency, taking into account external factors, do not allow choosing a module with effective power. To study the parameters of solar batteries, an equivalent circuit and methods for determining its parameters are presented. The established dependence of the excess of the SM temperature over the ambient temperature on the power of solar radiation is presented, which formed the basis of an improved method for determining the parameters of solar batteries. The presented results of the study allow at the design stages to determine the expected power of a solar photovoltaic installation and choose its optimal parameters.
