OVERVIEW

The course covers topics that provide the foundations of infrastructures related to electric mobility and shipboard electrical power systems, from both a modelling and methodological perspective. The focus is on two main areas: i) the planning and management of electric vehicle charging infrastructures; ii) network architectures and control techniques for shipboard electrical power systems.

AIMS AND CONTENT

LEARNING OUTCOMES

The module aims to illustrate the methodological and technological aspects related to electrical systems used in terrestrial electric mobility and on board ships. Management strategies for electric vehicle charging are proposed, considering the integration with renewable sources and multi-vector energy systems, smart charging, and vehicle-to-grid and vehicle-to-building technologies. Typical architectures and control techniques for shipboard power systems are analysed, considering the availability of storage systems, as well as the shore-connection infrastructures for connecting ships during docking.

AIMS AND LEARNING OUTCOMES

At the end of the teaching unit, the student will have acquired fundamental skills regarding the methodological and technological aspects related to the following main areas.

Area of infrastructures related to electric mobility:

• analysis of AC and DC charging systems for electric vehicles, integrated with renewable power plants, microgrids and "prosumer" buildings;
• definition of smart charging strategies for electric vehicles and application of vehicle-to-grid and vehicle-to-building technologies;
• assessment of the impact of electric mobility on the national electric power system; analysis of the role of electric vehicles within energy markets;

Area of shipboard electrical power systems:

• classification of ships and distinction of the main propulsion systems, with particular focus on integrated power systems;
• analysis of AC, DC, and hybrid system architectures, of the related control and protection requirements, and definition of the microgrid concept applied to shipboard electrical power systems;
• analysis of integration, control, and power management aspects in the presence of energy storage systems; analysis and design of shore-connection infrastructures.

EXAMS

EXAM DESCRIPTION

Each student is required to prepare a written report on the analysis of a case study, carried out individually or in a group with other students.

A positive evaluation of the written report grants access to the oral examination, which consists of theoretical, methodological, and practical questions, as well as the solution of numerical exercises.

Students who have valid certification of physical or learning disabilities on file with the University and who wish to discuss possible accommodations or other circumstances regarding the exams, should speak both with the teachers and with the School's contact person for disability.

ASSESSMENT METHODS

Evaluation of the acquisition of practical and theoretical competencies in developing analyses and calculations on electric mobility infrastructures and shipboard power systems.

FURTHER INFORMATION

Students have to install Matlab software on their computer to be able to implement the mathematical models proposed during the lessons.
