The continuous growing in environment requirements combined with the proximity of ports to city centers make it necessary to take actions in favor of the site de-carbonization. Therefore the electrical distribution grid of port needs to be analyzed and renewed for reducing the CO2 equivalent mass produced. This goal can be reached by using an integrated monitor systems in order to impose a desired power-flow and proper voltages on the different grid nodes. Not only the possibility of supervising the grid but also some notable functionalities are enabled by these innovative systems: for example cold ironing hubs, electrical vehicle recharge hubs, optimization of power generation and storage functionality. In this paper, the Port of Trieste is taken as case of study and possible evolution scenarios will be presented using a mathematical model of the medium voltage power system. Particularly, an innovative real-time hierarchical monitor system architecture will be discussed, while a patched Linux PC will be presented as possible monitor device implementation.
