Green Smart Port Energy System Design: Optimal Sizing

Abstract

The paper proposes an optimal sizing methodology for a green smart port with the presence of renewable energy resources and two energy carriers: electricity and hydrogen. The problem solution provides the optimal size of all the resources, taking into account a defined optimal energy management strategy. A notional smart port equipped with renewable resources has been used as study case, with the inclusion of data obtained from a real port to emulate the shore to ship power demand. The results show that the management strategy highly affect the optimal sizing solution, being the capital cost counterbalanced by the operational cost in an open market scenario where energy can be exported from the smart port to the national grid.
