| Abstract Scope |
The wide availability of fossil resources in some solar belt countries, and the need for tight temperature control of aluminum production cells have made constant gas powered operation smelters become the norm. In the UAE, solar energy plants achieved 0.24 $/kWh record, making solar energy competitive with fossil fuel energy. This study develops power modulation curves for aluminum production cells to accommodate variable renewable resources like solar PV. The study identifies the constraints imposed by the aluminum cell thermal response and the corresponding feasible heat transfer coefficients. A simplified transient FEM of an aluminum cell with variable internal heat generation is developed. Our models quantify the benefits of switching to a power modulation operation and estimate the requirements of the heat exchangers needed to achieve this transition. This research contributes to fill the gap in the study of power modulation to accommodate variable renewable energy sources in aluminum production. |
