Optimization model for cogeneration of hydro and geothermal power
Iceland and its people have been known for their ability to produce green energy using the country’s natural and pure resources. Today, Iceland’s main energy sources are hydro and geothermal power. Water level in hydropower reservoirs varies between seasons as it is at its lowest during winter and h...
