Coordinated Power Restoration Strategy of Electric Vehicles and Emergency Power Supply Vehicles Considering Multi-Temporal Domains
[Objective] To address the problem of critical load power restoration after distribution network faults, a coordinated power restoration strategy integrating electric vehicles (EVs) and emergency power supply vehicles (EPSVs) across multiple temporal domains is proposed. [Methods] A multi-temporal EV equivalent power source model is established to characterize the available power capacity of EV fleets under summer, winter, workday, and holiday scenarios. A load outage loss assessment model considering load importance, capacity, and outage duration is developed. On this basis, a two-stage EV-EPSV coordinated scheduling model is constructed and solved using genetic algorithm (GA) and adaptive large neighborhood search (ALNS). [Results] Simulation results show that, compared with the EV-only scheme, the EV+EPSV heuristic scheme achieves a load outage loss saving rate of approximately 9.51%-16.19%, while the proposed coordinated scheme achieves a load outage loss saving rate of approximately 34.49%-70.36%. Under the same coordinated restoration framework, ALNS outperforms local search (LS) with a saving rate of approximately 15.97%-49.18%. [Conclusions] The proposed strategy can exploit the temporal complementarity between the rapid response of EVs and the mobile compensation capability of EPSVs, effectively reducing load outage losses and improving power restoration efficiency after distribution network faults.

针对航空复杂回转件制造车间在物料配送中常常面临的物料供应不及时、路径规划难等难题,分析车间物料配送特点与约束条件,以带时间窗的车辆路径优化问题为基本模型,以最小化综合小车调用数量、总行驶距离、送达时间惩罚成本三者的配送成本为优化目标,构建物料配送路径规划模型,设计一种混合自适应大邻域搜索遗传算法进行求解,考虑车间物流通道的复杂性预先求得两工位间的实际最短可行路径,进而进行工位间的配送路径规划。通过车间实际案例与经典标准案例的验证和对比分析,评估了所提算法在不同规模配送问题上的优化效果和性能表现。
Aiming at the aviation complex rotary parts manufacturing workshop in the material distribution often faced by the material supply is not timely, difficult path planning and other difficult problems, analysis of the workshop material distribution characteristics and constraints, with a time window of the vehicle path optimization problem as the basic model, to minimize the integrated trolley call number, the total distance travelled, the delivery time penalty cost of the distribution cost as the optimization objective, to build the material distribution path planning model, design a hybrid adaptive large neighborhood search genetic algorithm to solve the problem. A hybrid adaptive large neighborhood search genetic algorithm is designed to solve the problem, and the actual shortest feasible path between two workstations is obtained in advance considering the complexity of the logistics channel in the workshop, and then the distribution path planning between workstations is carried out. The optimization effect and performance of the proposed algorithm on different scale distribution problems are evaluated through the validation and comparative analysis of the actual cases in the workshop and the classical standard cases. |
