PHOTOVOLTAIC POWER PLANTS WITH ELECTROCHEMICAL AND THERMAL ENERGY STORAGE IN IRAQ

Abstract

The relevance. One of the most environmentally friendly and reliable sources of natural energy is modern energy production technologies, especially renewable energy. This article introduces the concept of a hybrid solar storage system using a photovoltaic plant with electrochemical and thermal storage of electricity generated. For example, a region with a high level of solar radiation – Baghdad (Iraq). Studies were conducted for a model of social facility – a gym in Baghdad that needed electrical power and hot water supplies. The main aim of the research is tostudy the possibility of reducing the cost of photovoltaic installation using solar electrochemical and thermal electricity batteries. Objects: photovoltaicsystems for social facilities with a large share of electrical heating loads in areas with a high level of solar radiation, for example, a gym in Baghdad (Iraq). Methods: a combined method of accumulating solar energy: in electrochemical batteries and in thermal ones, methods of engineering sciences, modeling method. Results. The technical and economic efficiency of the local power supply system with a high percentage of thermal loads was analyzed taking into account the instability of solar radiation during the seasons of the year, temperatures, and energy consumption tables. The economic efficiency of the electrochemical battery of a photoelectric plant with a solar water heater collector was compared.
