The application discloses a mine truck cableway energy circulation system and a collaborative control method. The circulation system comprises a mine truck, an energy hub vehicle, a mine area power grid and a control center. The mine truck is connectable with another mine truck. The energy hub vehicle is connectable with the mine truck. The mine area power grid is connectable with the mine truck and the energy hub vehicle. The control center is signal-connected with each mine truck and the energy hub vehicle. The collaborative control method comprises an uphill scheduling method and a downhill scheduling method. The uphill scheduling method is that when the residual power of an uphill mine truck is lower than a minimum threshold, another mine truck or the energy hub vehicle on the downhill is used to charge the uphill mine truck. The downhill scheduling method is that when the residual power of a downhill mine truck is higher than a maximum threshold, the downhill mine truck is used to charge another mine truck or the energy hub vehicle on the uphill. Compared with the prior art, the circulation system and the collaborative control method fully recover the downhill energy of the mine truck through the direct connection of the uphill and downhill mine trucks or the energy storage and transfer of the energy hub vehicle, and thus the waste of energy is avoided.

This invention discloses a method for energy community electricity-carbon differential matching based on an improved slime mold algorithm, belonging to the field of smart grids. First, considering the coupling characteristics of energy hubs at the distribution network level, a data-driven method is used to quantitatively analyze the peak-valley coupling potential between different types of energy hubs. Initial differential matching is then performed on energy hubs with different external characteristics. Combining the load characteristics and carbon quota balance of energy hubs, a comprehensive index system that considers both regional structural and functional needs is constructed. Finally, aiming for optimal overall energy community characteristics, a matching strategy based on an improved slime mold optimization algorithm is proposed, introducing an adaptive search mechanism and information sharing strategy to optimize the structure and boundaries of the energy community. This invention simulates the dynamic matching process of energy communities, achieving differential matching that considers both electricity and carbon quotas, efficiently and accurately determining the boundaries and optimal matching schemes of energy communities, providing a new approach to improving the comprehensive benefits of electricity and carbon emission management.
