Coordinated Dispatch Strategy for Different Types of Industrial Loads Participating in Power Grid Based on the Source-Load Complementary Characteristics

Electric heavy-duty truck battery swapping stations, cement production, and aluminum electrolysis have high-energy-consuming industrial loads. Due to the barriers within the industrial load operating levels, there is a lack of effective dispatch strategies among different types of loads. To enhance the control flexibility of new power systems and the rapid adjustment capability of load resources, this paper first proposes a multivariate mixed Copula function to model and analyze the complementary characteristics of the load distribution resources among electric heavy-duty truck battery swapping stations, cement, and aluminum electrolysis. The study explores the complementary characteristics and capabilities of adjustable loads from different types of industrial loads. Subsequently, a joint adjustment method index is proposed based on the source-load complementary characteristics, and the coordinated scheduling strategy for different types of source-load participation in grid operation is studied. Finally, an example is provided to analyze the effectiveness of interactive coordination control of different types of industrial loads across various time scales.
