AN OPTIMAL DESIGN OF CONNECTIVITY OF THE ELECTRIC CURRENT TO A STAND-ALONE COMPLEX BY USING THE SOLAR CELLS

In recent days, the increasing demand for electrical energy has led to a significant need for power for the renewable energy. Producing the electric current from the Solar Energy (SE) is one of the best sources of renewable energies. The most significant problem facing designers of (SE) systems for individual buildings is the problem of lack of flat roof areas of these buildings, especially in the stand-alone systems where the solar panels take a considerable amount of space. Therefore, most scientific research in the field depends on "How to reduce the solar panel area with a high efficiency and power production." It is also possible that the available area gives a large surplus of useless energy. The problem of the vast horizontal areas of solar panels can be solved in the stand-alone systems, where each solar system installed on every building feeds that same building and feeds its surplus energy in main busbar around the complex. The main busbar around the complex provides each building with the required energy and uses the surplus energy from all buildings to provide another load. This paper introduces a complete design system of integrating photovoltaic/battery storage to a stand-alone complex isolated about the utility grid system "Off Grid system” with variety and different loads by using distributed solar cells to reach the highest efficiency and economical operation of the distribution system.
