ABSTRACT With the high proportion of renewable energy connected to the power grid, it has become more and more difficult to regulate residential and commercial loads, and industrial loads are urgently needed to participate in the regulation. Industrial loads face strict constraints, making their participation in grid regulation challenging. To this end, this paper analyses the tunable resource characteristics of the fused magnesite production process, and establishes a mathematical model to describe the strong constraints of its production work. Based on this model, a two‐layer optimisation model is developed for wind and photovoltaic power absorption and fused magnesite load regulation. The upper layer aims to maximise the system's new energy consumption, while the lower layer optimises the economic operation of thermal power units using the total power and renewable energy output determined by the upper model. Finally, the effectiveness of the optimisation model is verified by comparing different fused magnesite load adjustment ratios, considering the energy consumption and cost, using the CPLEX solver and comparing the simulation of typical cases. The results show that the proposed optimisation model increases the new energy consumption rate by 93.89%, reduces the system operating cost by USD 537.29, and provides strong support for the construction of new power systems.
