Feasible set deduction based method and system for simulating full-time state decision of vehicle and pile road network

This invention provides a method and system for real-time decision simulation of vehicle-pile-road network based on feasible set derivation. The method uses a pre-constructed multi-model fusion architecture to perform parallel load data prediction based on the spatiotemporal feature set of the acquired vehicle-pile-road network system. Based on the load data prediction results, a fused load prediction result containing confidence intervals is output through a dynamic weighted fusion strategy. Then, based on the fused load prediction results, a feasible decision set for each electric vehicle is constructed by comprehensively considering multi-dimensional factors. Based on this feasible decision set, under the premise of satisfying the distribution network safety constraints, a production simulation strategy containing the openable capacity of transformer substations and vehicle access instructions is obtained using a pre-constructed openable capacity assessment model. This solves the problems of large load fluctuations, complex time-series characteristics, inaccurate transformer substation capacity assessment, and difficulty in effectively fusing multi-model prediction results caused by large-scale electric vehicle access to the distribution network.
