The experimental studies of operating modes of a diesel-generator set at variable speed S G Obukhov, I A Plotnikov, M A Surkov et al. -Harvesting energy an sustainable power source, replace batteries for powering WSN and devices on the IoT A Pop-Vadean, P P Pop, T Latinovic et al. Abstract. The article describes the technical proposals to improve environmental and resource characteristics of the autonomous power supply systems of mobile communication base stations based on renewable energy sources, while ensuring the required reliability and security of power supply. These include: the replacement of diesel-generator with clean energy sourcean electrochemical generator based on hydrogen fuel cells; the use of wind turbines with a vertical axis; use of specialized batteries. Based on the analysis of the know technical solutions, the structural circuit diagram of the hybrid solar-wind-hydrogen power plant and the basic principles of the algorithm of its work were proposed. The implementation of these proposals will improve the environmental and resource characteristics.

The article considers the problem of optimization of telecommunication systems based on improving the dynamics of information flows. This task is formulated on the basis of a systematic approach, which consists in the fact that a multidimensional indicator is chosen as a system indicator, taking into account not only the connections of elements, but also the degree of use of these connections in the functioning of the network. This allows you to distribute information flows by changing the elements of the route matrix in the model of an open queuing network in order to optimize the system. It is shown that it is expedient to solve the optimization problem by applying the developed algorithm for the general solution of the problem. Algorithm procedures for the dynamics of information flows imply the transfer of part of the load of the elements that are bottlenecks to other elements of the system. The performance of the algorithm is confirmed by an example.
