Energy: In the face of ever-increasing energy consumption and costs, a smart port microgrid provides a unique opportunity for integrating the latest smart grid technologies to improve energy functionality and enable advanced management and control of energy consumption [36, 37].
Consequently, ship energy systems based on the use of an electrical microgrid are coming to the fore as an increasingly popular alternative solution. However, managing the energy flows within a shipboard microgrid can be highly challenging due to the multiple energy sources (including renewable energy sources) and types of loads involved.
Shipboard microgrid energy management incorporating ESS Energy management in the multi-source stand alone microgrid of an energy ship can be seen as an optimization problem. An optimization problem is a complex task that involves finding the minimum value of a cost function while accounting for various constraints.
They include propulsion loads, ship service loads, and pulsed loads. The PMS/EMS acts as a coordinator between the ship loads and power sources. A shipboard microgrid also includes electronic converters, transmission networks, communication lines, and other auxiliary components that enable the integration and operation of different energy sources.
