Abstract
THE PURPOSE. Exploring the possibility of building hybrid power plants to reduce the shortage and cost of energy in Iraq through the combined use of solar electrochemical and thermal batteries.
METHODS. Analytical methods in the field of construction of consumer energy supply systems from photovoltaic plants, methods of computer-mathematical modeling.
RESULTS.The analysis of daily algorithms for the operation of a solar thermal energy supply system was carried out using the example of a social facility in Iraq using electrochemical and thermoelectric energy storage systems, taking into account the variation in the level of solar radiation, ambient temperature and energy consumption by seasons. An optimal algorithm for the conditions under study is proposed for the operation of the solar energy supply system and its elements. Methods for building an intelligent thermoelectric controller have been defined, which ensure the conversion of the maximum available energy of the PV power plant into thermal energy.
CONCLUSION. It turns out that the proposed structure for the construction of photovoltaic power plants with combined storage of electricity is preferable to consumers with large thermal loads, because of the efficiency of direct conversion of electricity from photovoltaic modules to thermal energy is higher than the efficiency of thermal conversion through an intermediate link - an electrochemical battery. The paper proposes the principle of creating intelligent thermoelectric controllers, which ensure the operation of a photovoltaic power plant in maximum power mode.
