Reduction of energy costs and grid instability with energy flexible furnaces

Due to the fluctuations in energy generation from renewable sources, electricity prices on the stock exchange are often subject to strong variations and the control reserve market is becoming increasingly important. In this paper we simulate a flexible furnace that can reduce energy costs of electrical furnaces by varying the energy supply without interrupting the production output rate by using the molten metal bath as storage. The flexible furnace modeled can reduce its power supply and thus contribute to the stabilization of the energy grid.
