AI Technical Summary

Technical Problem

Existing technologies lack detailed representation of energy changes during the stopping phase in the dynamic scheduling of virtual energy storage power stations for electric bus fleets. This leads to uneven scheduling and delayed response in scenarios with load fluctuations and rapid changes in vehicle status, making it difficult to achieve consistent energy determination over time.

Method used

By acquiring the entry and exit records and state of charge values ​​of electric buses, stopping intervals are divided and time segments are segmented to determine representative state of charge values. Combined with the energy demand and load demand of the vehicles, a virtual energy storage capacity interval for electric buses is formed. The available capacity sequence is organized according to the vehicle dimension, and finally matched with the grid load to form a scheduling sequence.

Benefits of technology

It achieves accurate mapping between state of charge and time series, improves the consistency of dispatch response and the coordination capability of group output, enhances the unified time base mapping of grid load and vehicle resources, and solves the problem of inconsistent time scales in the dispatch process.
