Process optimization is a highly successful method for achieving optimal efficiency in industrial production. The conventional approach presupposes that the operational parameters should align with settings. However, it fails to consider that, influenced by stochastic performance of control loops, operating may deviate from Consequently, this results violation constraints and affects production safety. Therefore, paper proposes an uncertainty considers loops accurately determine can be practically achieved Firstly, multi-optimization variational mode decomposition strategy developed precisely extract smooth random trend terms loop output data. Secondly, grouping smooths out characterizes associated these terms. Subsequently, moment set mild mean-zero net condition then defined construct improved distribution robust model considering loops. Finally, validation proposed actual hydrocracking process shows error reduced more than 10%, constraint rate 14%, which fully proves effectiveness applicability method.

Hydrogen-Integrated energy systems (HIESs) are pivotal in driving the transition to a low-carbon structure China. This paper proposes economic scheduling strategy improve operational efficiency and reduce carbon emissions of HIESs. The approach begins with implementation stepwise trading framework limit output system. is followed by development joint model that combines hydrogen use capture. To supply flexibility HIESs, modifications conventional combined heat power (CHP) unit made incorporating waste boiler an organic Rankine cycle. results flexible CHP response capable adjusting both electricity outputs. Furthermore, comprehensive demand designed optimize capacities electric thermal loads, thereby enhancing demand-side responsiveness. integration vehicles (EVs) into system analyzed respect their consumption patterns dispatch capabilities, which improves potential for enables optimized synergy between operations. Finally, HIES developed objective minimizing costs. show proposed method effectively enhances economy, performance, operation while promoting clean consumption, deep decarbonization system, synergistic complementarity supply–demand resources. In broader context expanding growing EV adoption, this study demonstrates energy-saving, emission-reduction vehicle-to-grid (V2G) strategies contribute sustainable green sector.
