Abstract

Seaports, as substantial consumers of energy, aim to adopt energy management systems in response to rising energy costs and a commitment to sustainable operations. Many ports are shifting to electricity as their primary energy source, opting for fully electrified equipment like electric vehicles (e.g. battery AGVs) instead of carbon-intensive alternatives. This paper presents a mixed integer linear programming model designed to address the integrated planning and energy management challenges faced by seaports utilizing a port microgrid. The planning module of the model determines the allocation of electric vehicles and related equipment, as well as the scheduling of EV charges, specifying the energy usage for each one-hour period. Additionally, the planning module decides the berthing duration for each ship, influencing the hourly energy consumption of the port. The energy management aspect involves aligning energy demand and supply, considering various energy pricing schemes, bidirectional energy trading among different sources (such as the utility grid, renewable energy sources), and integrating energy storage systems. The study's findings suggest that the implementation of smart grid technology, represented by the port microgrid, can yield substantial cost savings compared to traditional setups. Notably, efficient charge planning and battery management within microgrid systems enable ports to achieve significant cost reductions.
