Abstract:With the construction of a high proportion of renewable energy power systems, the flexibility of power grid regulation is facing new challenges. In addition to power supply side and power grid side, high-energy-consuming industrial loads on demand side have great potential to improve the flexibility of power grid regulation. However, currently, high-energy-consuming industrial loads lack the means to explore and improve the flexibility of power grid regulation, so the degree of its participation in demand side response of power grid is not ideal. Taking electrolytic copper load which is a typical high-energy-consuming industrial load for example, its process flow is studied and a process flow model is established. The production equipment with power regulation feasibility in process flow is analyzed, and a power control model is established based on its power characteristics and process coupling correlation. Finally, taking the participation of electrolytic copper load in demand side response of power grid for example, the effectiveness of the proposed power control method for electrolytic copper industrial load participating in demand side response is verified by comparing it with only switching load control methods, which provides an effective power control method for high-energy-consuming industrial load participating in demand side response of power grid.
