An Optimal Operation Strategy for Integrated Energy-Logistics System in Green Port

Increasing penetration of renewable energy sources in the green ports calls for more flexible regulation approaches. This paper proposes an optimal operation strategy for the integrated energy-logistics system to minimize the operation cost of a green-port multi-energy microgrid. A comprehensive model for hybrid hydrogen-battery-thermal energy storage is established for the operation optimization of the emission-free energy system. A coordinated demand management approach for the thermal and electrical loads of reefer containers is developed to enhance the flexibility of logistics system. Considering the demand managements of the logistics system, the life degradation properties of energy storages and the operation costs of the renewable energy sources, the whole optimization model is formulated as a mixed integer linear programming (MILP) problem. Numerical simulations are carried out to verify the merits of the proposed operation strategy.
