This study investigates the design and optimisation of a hybrid microgrid system to power a 70 MW magnetite iron ore processing plant in Midwest, Western Australia. Integrating solar PV, wind turbines, advanced storage solutions, and diesel generators, the system leverages the region’s abundant renewable resources to achieve economic, environmental, and operational benefits. Using the Hybrid Optimisation of Multiple Energy Resources (HOMER) software, the optimised configuration reduces annual operating costs by $109 million, decreases CO₂ emissions by 75%, and delivers a reliable energy supply with a levelised cost of electricity (LCOE) of $0.345/kWh, compared to $0.409/kWh in the diesel-only base case. These findings demonstrate the potential of hybrid microgrid systems to support sustainable industrial operations while aligning with national decarbonisation goals and advancing environmental stewardship.

摘要

This study investigates the design and optimisation of a hybrid microgrid system to power a 70 MW magnetite iron ore processing plant in Midwest, Western Australia. Integrating solar PV, wind turbines, advanced storage solutions, and diesel generators, the system leverages the region’s abundant renewable resources to achieve economic, environmental, and operational benefits. Using the Hybrid Optimisation of Multiple Energy Resources (HOMER) software, the optimised configuration reduces annual operating costs by $109 million, decreases CO₂ emissions by 75%, and delivers a reliable energy supply with a levelised cost of electricity (LCOE) of $0.345/kWh, compared to $0.409/kWh in the diesel-only base case. These findings demonstrate the potential of hybrid microgrid systems to support sustainable industrial operations while aligning with national decarbonisation goals and advancing environmental stewardship.
