Nowadays, the industrial world is undergoing a disruptive transformation towards more
environmentally sustainable solutions. In the blue economy, this new approach is not only expressed
in the domain of actual vessels, but also in the development of charging infrastructure, displaying a
notable transition towards more eco-friendly solutions. The key focus lies in adopting flexible power
systems capable of integrating renewable energy sources and storage technologies. Such systems play
a crucial role in enabling a shift towards low-emission maritime transport. The emissions reduction
goal extends beyond onboard shipboard distribution systems, encompassing also the design of supplying
platforms and marinas. This study explores the implementation of a controlled DC microgrid
tailored to efficient management of power flows within a yacht marina. Once having established the
interfaces for the vessels at berth, the integration between the vessels, the onshore photovoltaic plant
and the battery storage unit is made possible thanks to the coordinated management of multiple
power converters. The overarching goal is to curtail reliance on external energy sources. Within
this DC microgrid framework, a centralized controller assumes a pivotal role in orchestrating the
power sources and loads. This coordinated management is essential to achieve sustainable operations,
ultimately leading to the reduction of emissions from both ships and onshore power plants.
