Design, Sizing, and Energy Management of Microgrids in Harbor Areas: A Review

Abstract

Energy efficiency and low-carbon energy systems are increasingly taken into account in seaports, due to climate change challenges and the evolution of environmental regulations. Thus, technological breakthroughs must be brought to numerous systems in harbors, such as harbor cranes, seaport vehicles, or the power supply of berthed vessels. These aspects may require the establishment of a microgrid in the harbor area. Microgrids have been subjected to a wide development on the mainland and islands, mostly for domestic loads. However, these are still scarce in harbor areas. Their development in such places faces several challenges, such as high power requirements, monitoring and management of a wide range of loads, energy policy framework, etc. Moreover, the establishment of a microgrid involves a study of sizing and of energy management, to avoid prohibitive costs and to verify load requirements. This paper provides a literature survey related to the development of microgrids in seaport areas. Firstly, the main components that occur in harbor microgrids are listed, and then a review of studies dealing with sizing and energy management is proposed. Finally, from this survey, innovative concepts and barriers are listed, with an up-to-date review of microgrid development in seaports worldwide.
