Basics of Electrical systems

The course introduces the student to the knowledge of the operation of the wholesale electrical market in Italy, both in its structural components and in organizational aspects, and a first comparison with European market models.
The course introduces the student to the Smart Grid technology, that is the evolution of the traditional Power Grid. A smarter Grid is required in order to cope with a number of old and new problems mainly due to the increasing of Renewable energy sources (from sun, wind, water), which are endowed with smaller power and more extended distribution on the territory (the so called Distributed Generation). Therefore, a more flexible and fast management of the Grid is required, in order serve properly any industrial and domestic client. The course aims at making the student more familiar with the concepts and technologies required to implement a Smart Grid, and unusual for a traditional Electrical Engineer education. The main topics are: Communication protocols for Smart Grids; Smart Metering devices and systems; Smart Grid Actuators: FACTS.

- Operative states of the electrical system; definitions proposed in the technical literature: difference between normal state, alert and emergency.
- Load flow calculations; calculation of the operating conditions of the electrical system. Definition of network load; load and generation nodes; the role of the slack bus. Solution methods; Newton-Raphson and decoupled calculation Methods (Carpentier, Stott). Approximate Calculation Methods (Direct Current Load Flow)
- Electricity Markets; fundamentals concepts to understand the dynamics of the market and the interrelations between its various phases; specialized analysis of regulation, use of simulation models, critical analysis of the market performance based on the development of public data, investment appraisal; system planning strategies
- Motivation of the passage from a traditional power distribution grid to a Smart Grid. The role of renewable energy sources and of the distributed generation; the problems to be matched by new technologies.
- Definition of a Smart Grid and its Architecture.
- The role of data and information communication. Basics of a Digital Communication Protocol. The main Protocols for Smart Grid implementation.
- The role of Smart Metering. The new meters: technology and integration in a Automated metering Infrastructure.
- The role of new Power Actuators, based on Power electronics (FACTS) and Automatic control architectures.

The course is based on frontal lectures.

The lectures are based on Power Point presentations which are made available at the students. Also scientific paper and other useful material is made available from the teacher through the Kiro platform.
