93041 - ELECTRICAL POWER SYSTEMS FOR SMART CITIES M

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 (e.g. light railways), 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 of 30 and 30 hours respectively: in the first 30 hours of lectures (Professor Carlo Alberto Nucci) the principles, the structure of the electrical systems, as well as the theoretical basis for their design and the connection to them of renewable source generators is provided; the module 2 of 30 hours (Professor Stefano Lilla) is devoted to the electric vehicles power systems and to their grid integration.

The course program is as follows:

Module 1: Introduction to electric power systems; Power Flow analysis; Power systems stability; Voltage and Reactive Power control; Frequency and Active Power Control. Charging stations impact on the distribution grid management and development. Test cases solution using the Electromagnetic Transient Program.

Module 2: Electric vehicles (EV) framework, classification and battery state of charge optimization (Dynamic Programming); Low voltage distribution systems and safety; EV electrical safety; Microgrids and Energy Management System optimization (Linear, Non-Linear and MIP programming); Grid integration of EVs and optimization (vehicle-to-grid V2G).
