Development of energy-saving technology to maintain the functioning of a wind-solar electrical system

“…Making preliminary decisions on changing the power of a thermoelectric battery makes it possible, while maintaining the capacity of the rechargeable battery, to ensure a change in the temperature of heated local water, based on changing the number of rotations of the circulating pump's electric motor in terms of water flow rate, thereby reducing the charge duration by up to 30 %. The results reported in the current study is continuation of work that addresses the adjustment in energy generation and consumption [1,[12][13][14]. The obtained results could be used in the development of intelligent systems for operating the hybrid charge controllers in terms of maintaining the functioning of wind-solar electrical systems.…”

“…Based on the methodological and mathematical substantiation of the architecture of technological systems [1,[12][13][14], the architecture and mathematical sub-stantiation of the technological system's architecture for the operation of a wind-solar electric system have been proposed. Its basis is the integrated dynamic subsystem, which includes the following components: a wind-energy installation, a photoelectrical module, a hybrid charge controller, an inverter, an array of rechargeable batteries, a thermoelectric battery (Fig.…”

“…1. Architecture and mathematical substantiation of the architecture of a technological system: 1 -charge unit; 2 -discharge unit; 3 -unit to estimate functional efficiency, where WEI -wind-energy installation; RB -rechargeable battery; TEB -thermoelectric battery Mathematical notation ( 1) is based on the mathematical substantiation of the architecture of technological systems, the methodology of mathematical description of the dynamics of energy systems, the method of causation graph [1,[12][13][14]. ), ( , ), ( ), (…”

“…Thus, for example, based on the mathematical and logical modeling related to the technological system of functioning of a rechargeable battery, the technology has been devised to support a change in the battery capacity, based on predicting a voltage change when measuring the temperature of the electrolyte in the volume of rechargeable batteries. Application of the integrated evaluation system of voltage change, obtained on the basis of adjusting the electrochemical and diffusion processes of discharge and charge, makes it possible to take timely decisions about additional charging to prevent recharge and inadmissible discharge [1].…”

Complex mathematical modeling of heat pump power supply based on wind-solar network electrical system

“…In [7], a model for prioritizing sensitivity to changes in data is presented, based on accurate measurement of electrical energy consumption. In terms of connection to intelligent control systems in [8], it is proposed to predict voltage changes when measuring the temperature of the electrolyte in the volume of batteries. An energysaving technology has been developed for the operation of a storage battery; it does not allow overcharging, but it does not allow discharge based on the coordination of electrochemical and diffusion processes of discharge and charge.…”
