(10) Diesel Generator According to the available two diesel generators are anticipated for emergency goals, however the main goal is to minimizing the usage of the generator because of the environmental considerations. In addition, in the model it is obligated to use the diesel generators just in the emergency cases such as outage for long time. According to different emergency scenarios the capacity of the tank is determined for the worst case scenario which is the one week of supplying the whole site, so 200 hours is forecasted for the tank capacity determination. By using (11) diesel generation is calculated. Total cost of the diesel gen contains the capital cost and operation cost of the diesel gen is derived by (12). In (12) is the consumption rate of diesel gen in and is the cost per gallon in. (11) (12) Storage One important aspect of using renewable energy is reliability. Since most of the renewable sources are intermittent, it is important to have storage backup. In the proposed design, it is focused on battery sizing. Solar energy is available during the day and even during the day it is not guaranteed that panels will get full solar irradiance because of shading, dirt and bad weather condition. A similar behavior is exhibited by wind power generation due to variability of wind speed throughout the day and night. So it is important to have extra energy stored in batteries for night time usage. Furthermore, when having battery storage, it is sometimes more economical to buy electricity from the main grid and store it to use during peak periods. Increased reliability of the overall system is another advantage of buying and storing electricity.
