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.

With the transformation of energy structure and development new power systems, higher requirements have been put forward for performance stability microgrids. To adapt to multi-information, multi-energy, multi-business characteristics microgrids, this paper proposes a cyber-physical system (CPS) based microgrid simulation platform, which constructs an integration architecture composed physical system, main station strategy system. Through interaction information businesses, real-time reproduction state control business scenarios are achieved. The platform innovatively introduces theory finite machine (FSM) designs transition strategy. Taking fault optimization as example, optimal path can be selected through transition, effect is improved on FSM. Compared traditional methods, reduces time by 16% 86.6%, significantly shortening scene time. In addition, practical application value in operational efficiency improvement was verified building semi-physical rapid prototype (RCP) hardware-in-the-loop testing (HIL).
