Project abstract

The port industry is transforming towards smart ports by developing a sustainable maritime transportation system and greater electrification. In the process, approaches for the inclusion of renewables, emissions reduction are gathering momentum with advancements in technologies. Global containerization leads to high electricity demand at container terminals and the electricity demand is highly dynamic and dependent on different operation processes. A correctly forecasted electricity demand profile is crucial for less expensive and reliable power operation and planning. Parnian et al.[1] provides results of a forecast of the hourly peak load demand and short-term electricity demand profile in a container terminal in the Port of Gävle. Firstly in [1], Artificial Neural Network (ANN) method is used to predict the container terminal baseload demand. Second, the worst-case simultaneous peak load is estimated. Third, the day ahead load profile is modeled based on the handling operation scheduled for the day. This approach is implemented at the container terminal in Port of Gävle, and the results have been used in dialogue with the local energy company for the future predicted need of load.

Inputs from [1] have been used to assess the possibility of a future local energy system covering the port area. Therefore, the current project focuses on obtaining a suitable sizing of Photo-Voltaic (PV) electricity generation and battery storage systems. This includes forecasting the PV generation, modeling and optimizing the size of grid-connected PV-battery system for the port area. The ultimate aim is to weigh the Life Cycle Cost (LCC) against the reliability of the systems to arrive at the smartest design decision.
