Coordinated Power Control for Flexible and Sustainable Operation of DC microgrids in Yacht Marinas

Abstract

The innovation towards sustainable solutions is involving all the industrial sectors. In this context, the marine world is going through a great transition. The integration of renewable energy sources and the adoption of flexible power systems, like DC microgrids, are some powerful solutions to develop advanced and sustainable marine grids. These concepts are not only adopted in the onboard shipboard distribution, but also when conceiving supplying platforms and marinas. In this paper a flexible DC microgrid is proposed for a yacht-marina, and a coordinated power control is presented. The ships at berth, renewable sources and energy storages are all connected through multiple power converters. A centralized controller is demanded in managing sources and loads. By properly coordinating the photovoltaic modules, landed/embarked storage and power flows to/from the main grid, the attained goal is the sustainable operation of the yacht-marina DC microgrid.
