Description

Technical Field

[0001] The present invention relates to the technical field of power grid de-icing, and more particularly to a power grid de-icing strategy optimization method based on range icing. Background Art

[0002] Existing technologies for grid icing response often employ local response mechanisms based on node-level ice thickness thresholds. Strategy scheduling relies on fixed rules or manual experience, lacking systematic modeling of the overall grid topology and the impact range of power outages. This makes it difficult to support optimal allocation of ice-melting resources globally. Even some research has begun to incorporate ice thickness monitoring and equipment control models, but these efforts primarily focus on improving the efficiency of individual lines, and have yet to establish a scheduling system focused on minimizing total outage losses. As this solution is implemented and put into operation in multi-regional power grids, regional dispatch strategies based on the dynamic weight adjustment mechanism will continue to evolve adaptively. Based on the independent optimization of multiple regions, strategy biases and boundary inconsistencies may occur, resulting in a decrease in cross-regional coordination efficiency and affecting the overall dispatch stability. Therefore, the problem that needs to be urgently solved after the actual deployment of this solution is: how to maintain the coordination and boundary consistency of ice-melting dispatch behavior across the entire network based on the long-term evolution of the multi-region dynamic weight adjustment strategy.

[0044] It should be noted that in the formula structure involved in this solution, dimensionless terms can serve as proportionality or structural adjustment factors. When combined with quantities with units, they only play a numerical scaling role and do not introduce new physical dimensions. Therefore, they will not change or confuse the overall unit system of expression. This combination of "dimensionless terms and units" can be understood as a composite structural expression commonly used in mathematical and physical modeling, conforming to the principle of dimensional consistency and having a clear physical interpretation basis. Secondly, in the formula structure of this scheme, if multiple variables with different physical units are involved, including but not limited to time, mass or energy variables, their joint appearance is to express the collaborative modeling relationship of multiple physical mechanisms. Each variable can be formed into a unified structure through function mapping, ratio combination or normalization adjustment. The units and meanings are clear, and the overall expression conforms to the principle of dimensional consistency and the common formula of engineering modeling. In this solution, any design constants, weights, adjustment factors, threshold parameters, and proportional coefficients are adjustable control parameters for different application environments. Their values ​​depend on the target device configuration, data input characteristics, and performance optimization goals. During the implementation phase, they are set within a reasonable range through model verification, performance constraints, or engineering calibration. Although these parameters do not have unique preset values, they have clear adjustment logic and calculation paths, and are part of the deterministic setting process in engineering implementation. The purpose of such setting is to ensure that the solution is both universally adaptable, reproducible, and operable, without affecting its technical clarity and feasibility. The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
