This invention relates to an optimal scheduling method and system for an electro-hydrogen coupling system based on truck flexibility and relaxation-repair warm-start technology. The method includes: acquiring basic data of the electro-hydrogen coupling system; constructing a power system model, a hydrogen energy system model, a pipeline congestion management model, and a hydrogen truck transportation model, wherein the pipeline congestion management model is a truck-based pipeline congestion management model that treats hydrogen trucks as flexible resources; establishing constraints and constructing an optimal scheduling model with the goal of minimizing the total system operating cost over the entire scheduling cycle; transforming the optimal scheduling model into a convex programming model using a mixed-integer second-order cone programming reconstruction technique; and solving the convex programming model using a relaxation-repair warm-start algorithm, considering the physical state information of the system, to obtain the optimal scheduling result. Compared with existing technologies, this invention has the advantages of actively alleviating pipeline physical congestion and high computational efficiency.

The application discloses a power distribution network economic reactive power coordinated dispatch optimization method and device, a terminal and a medium. The scheme forms a closed-loop feedback of economic and reactive power optimization by constructing a cooperative optimization framework, and dynamically adjusts the optimization direction in the iteration process. At the same time, the combination of the Pareto solution and the second-order cone programming ensures the comprehensiveness of multi-objective optimization and overcomes the difficulty in solving non-convex optimization problems. In combination with the cross-iteration mechanism, the adaptability of the system to distributed power output fluctuation is enhanced, and the coordinated control of flexible load and energy storage improves the operation flexibility of the power distribution network. Therefore, the feasibility of the optimization scheme can be maintained under complex operation scenarios.
