Techno economic design and analysis of a hybrid renewable Energy system for Jazirat Al Halaniyat in Oman

This research aims to design a hybrid solar-wind-diesel- storage battery sustainable energy system for Jazirat Al Halaniyat (Island) in the Sultanate of Oman. Techno economic assessment and analysis were done by using the HomerPro software. Many factors were considered such as the weather conditions, availability of different renewable energy resources, life security, and economic factors. The weather conditions were found having limited impacts on the overall performance of the proposed system because of the successful technical integration of the wind and solar weather conditions during the summer period. Using the real load data for 2019 and 2020, at a peak load of 500 kW and an annual load demand of 2350 MWh, different hybrid generation solar, wind, diesel generator and storage battery configurations were examined for the best optimum sizing, minimum cost, and most stable system for 25 years period. The techno economic analysis results proved that the proposed system could run with a 1004 kW PV solar system, 160 kW wind turbine with a contribution of 580 diesel electricity generator and storage of 1478 kWh yearly. The proposed system is expected to produce an annual electricity production of 3,548 MWh/year, of which around 56.6% (2,007 MWh/year) will produced by the solar PV panels at LCOE of $0.234 per kWh.
