The paper aims to introduce an interesting concept of Power Management System, which adopts a full distributed architecture for achieving Smart Management of loads. An effective way to prepare and manage electric network with the increased demand, is to apply all the different techniques available in smart grids, such as load balancing, load shifting and peak shaving through the intelligent management of the load (ILM). This approach can be also used on vessel in order to perform different specific objectives in accordance to the PMS (Power Management System) or as a back-up solution of this component.
