Abstract

The embodiment of the invention discloses a method and device for determining an operation strategy of an electrolytic aluminum industrial park, and the method comprises the steps: determining a target operation strategy enabling a preset target function to be minimized from a plurality of candidate operation strategies of the electrolytic aluminum industrial park; wherein the target function comprises a target function under the condition that the electrolytic aluminum industrial park operates according to a candidate operation strategy; the operation and maintenance cost of a photovoltaic unit and an energy storage system in the electrolytic aluminum industrial park, the cost of purchasing and selling electricity from a superior power grid of the electrolytic aluminum industrial park, the carbon emission cost of the electrolytic aluminum industrial park participating in carbon market transaction and the cost of the electrolytic aluminum industrial park participating in green certificate transaction are converted into a target operation strategy; and determining an operation strategy of the electrolytic aluminum industrial park. Thus, collaborative optimization of multiple factors such as photovoltaic, energy storage, power grid electricity purchase and sale, carbon transaction and green certificate transaction is realized, through linkage with a multi-transaction market, the comprehensive operation cost of the park is effectively reduced, the energy economy and environment compliance of the park are remarkably improved, and the effectiveness of operation strategy optimization can be improved.
