AI Technical Summary
Existing robust scheduling methods for integrated energy systems in coal mines fail to effectively consider the mutually exclusive output correlation between coalbed methane and exhaust gas, as well as the coupling relationship between associated resource output and equipment energy consumption. This results in overly conservative scheduling schemes under multiple uncertainties, making it impossible to accurately identify real severe scenarios and leading to high operating costs or poor functional stability.
By introducing bidirectional adjustment parameters with reverse correlation into the source-load uncertainty set, the mutually exclusive output law between coalbed methane extraction flow and exhaust gas discharge flow is constrained, and the coupling deviation of resource processing energy consumption is superimposed on the total system load offset to construct a robust scheduling model, which is then solved using a column-constraint generation algorithm.
Accurately identifying real-world harsh scenarios for the system reduces scheduling conservatism, improves system economy and adaptability, avoids unnecessary cost waste, and enhances the system's robustness and stability under multiple uncertainties.
