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

Abstract

<p>An integrated system to support the functioning of a wind-solar electric system has been designed, based on predicting a change in the capacity of a rechargeable battery when measuring voltage at the input to a hybrid charge controller, voltage at the output from an inverter and the frequency of voltage. Taking preliminary decisions to support the capacity of a rechargeable battery related to a change in the capacity of a thermoelectric battery is based on establishing the ratio of voltage at the input to a hybrid charge controller to voltage at the output from the inverter, which are measured. A change in the rotational speed of the electric motor of the circulating pump has been ensured in terms of changes in consumption and the temperature of heated water by reducing charge duration by up to 30 %. An integrated mathematical and logical modelling of a wind-solar electric system has been performed, based on the mathematical substantiation of the architecture of a technological system and the mathematical substantiation to support the operation of a wind-solar electrical system. The basis for the proposed technological system is a dynamic subsystem that includes the following components: a wind-energy installation, a photoelectrical electrical module, a hybrid charge controller, and an inverter, an array of rechargeable batteries, a thermoelectric battery. The time constants and the coefficients for mathematical models of the dynamics have been determined related to a change in the capacity of a rechargeable battery, the rotational speed of the electric motor of the circulating pump, and consumption of local water. A functional assessment has been derived for a change in the capacity of a rechargeable battery, the rotational speed of the electric motor of the circulating pump, consumption of local water related to a change in the temperature of local water in the range of 30–70 °C. Defining the resulting functional information on forecasting a change in the capacity of a rechargeable battery makes it possible to take the following preliminary decisions: about changing the rotational speed of the electric motor of the circulating pump, about changing the consumption of local water. Maintaining the capacity of a rechargeable battery is carried out based on adjusting the generation and consumption of energy.<strong></strong></p>
