Optimal design and evaluation of a hybrid energy system for off-grid remote area

This paper discusses optimal solutions for supplying electricity to consumers in the Dibba area, which requires 27 MW of power. Data on wind speed and average monthly solar radiation were collected and projected seven-year power demand was assessed. According to HOMER software analyses, the best solution for Dibba according to the software would be a combination of wind, natural gas, and diesel. Pursuing such a hybrid energy solution would result in electricity produced for USD$ 0.0787/kWh. A solution incorporating multiple energy sources would require the lowest amount of fuel annually and would do the least damage to the environment due to a reduction in greenhouse gases emission. Using these hybrid systems for off-grid connections will definitely provide a safer power supply to Dibba while strengthening Oman’s existing power supply system.
