Abstract
With the development of ship electrification, the demand for energy in ports is increasing. The location and natural
resources of ports also create conditions for the development of ship electrification. This paper firstly analyzes the
current development status of floating solar power generation technology and offshore wind power generation
technology, summarizes the obstacles facing the development of offshore power generation platforms, introduces
the materials and structures that can be used for floating power generation platforms, and then introduces the port
microgrid topology from three aspects of AC microgrid (AC), DC microgrid (DC) and AC/DC hybrid microgrid
(AC/DC) hybrid structure, and compares the three structures. Then the existing control methods are reviewed
from the perspective of port capacity planning and the application of distributed control in port energy planning is
emphasized. Finally, port energy management strategies are introduced from the perspective of multiple time
scales, and relevant cases are listed, and the advantages and disadvantages of management strategies under
different time scales are compared. At the end of the paper, several advanced smart ports are given as examples,
and the new energy used by each port and its development scale are analyzed, and the future clean and efficient
ports are envisioned.

Keywords: Floating power supply platform, ports, microgrid topology, capacity planning, energy management
