Abstract

Nowadays with the expansion of energy consumption in industries and also running out of fossil fuels, taking advantage of new energy sources is essential. Solar and wind energy are more common among all renewable energy sources. Although renewable energy is less reliable in comparison with fossil fuels due to uncertainties in power production such as non-uniformity of radiation, Successive changes in wind speed and also mismatch in the times of electrical consumption and production. Therefore, it is necessary to use energy storage systems or diesel generators. On the other hand, high cost of purchasing and installing renewable systems requires to evaluating the power requirements and sizing of the battery, photovoltaic panels, wind turbines, and diesel generators precisely to minimize the energy costs.
