The Capacity Optimization and Configuration of a Centralized Shared Energy Storage System for Road Traffic Self-contained Microgrid with Multi-microgrid Structures

To improve the power supply reliability and renewable energy absorption rate in off-grid and weak-grid areas of the western region, this paper proposes a capacity optimization and configuration method for a centralized shared energy storage system in road traffic self-contained microgrids, considering the characteristics of multi-microgrid cluster structures. Aiming to minimize the construction cost of the centralized shared energy storage system and optimize the operational cost efficiency of microgrids in multiple service areas, the optimization model is solved using the Gurobi commercial solver, considering multi-microgrid interaction charging and discharging strategies. The effectiveness of the proposed method is validated through case studies.
