Valido anche per Laurea Magistrale in Electric vehicle engineering (cod. 6713)
Conoscenze e abilità da conseguire
The course deals with electric power systems for urban mobility. Two main aspects will be covered: - description and design of onboard power systems that enable the flexible and functional connection and coordinated operation of the vehicle energy sources, storage units and loads; - analysis of the power and energy requests of the vehicles from the grid and integration of the feeding infrastructure in the grid. The course will provide the knowledge for the evaluation of the impact of the charging stations to the planning, operation, control, and protection of power distribution networks. The course will provide basic notions on the concepts commonly referred to as Vehicle-to-Grid (V2G), Vehicle-to-Building (V2B) and Vehicle-to-Home (V2H). In this context, the vehicles are not seen by the network as simple loads, but they can contribute to the operation of the network or a microgrid with the provision of balancing and ancillary services.

The course covers the main key technical issues relevant to the operation and control of modern electric power systems able to supply ground transportation, with particular reference to road electric vehicles and urban mobility, including flexible and functional vehicle connection (coordinated operation with the energy sources) and the description of onboard power systems.
The course is divided into two modules: in the first one the principles, the structure of the electrical power systems, as well as the classical theoretical basis for their design and the connection to them of renewable source generators is provided; the second one is devoted to the microgrids, electric vehicles power systems and to their grid integration.
The course program is as follows:
Introduction to electric power systems and its evolution; Energy production and its evolution; Voltage and Reactive Power control; Frequency and Active Power Control; Power systems stability; Power Flow analysis; Power flow for radial network (backward/forward swing); DC Power flow; Economic dispatch problem. Test cases solution using the Electromagnetic Transient Program (EMTP): behavior of a HV feeder in different conditions and power flow in a HV network in a steady state.
Challenges in transportation systems and the power grid; MV and LV Distribution systems; LCA and emissions of light vehicles as a function of mix electricity production; Electric and hybrid light vehicles framework; Electrical safety and charging infrastructure (charging stations classification); Microgrids, energy management systems (EMS) optimization and role of batteries; Vehicle to grid (V2G) and system optimization. Test cases solution using Python and Matlab: LCOE examples; EMS and V2G optimization with Linear (simplex algorithm) and MIP programming.
