The course aims at giving the basic knowledge about distribution systems and smart grid
-Knowledge and understanding
deep knowledge and understanding of the fundamental theoretical and practical aspects of planning and operation of electric power distribution networks.
-Applying knowledge and understanding
Capability to analyse power distribution networks and to autonomously design distribution systems with distributed generation.
- Making judgements
Capability to correctly assess the operation and design of a distribution system with particular reference to the protection system
- Communication skills
Capability to communicate technical information both orally and in writing. Ability to discuss problems and solutions with specialists and non-specialists about the planning, design and operation of modern distribution systems.
- Learning skills
Capability of continuous learning, through the proper interpretation of scientific and technical literature, manuals of manufacturers and technical standards.


The knowledge of theory of physics, electric circuits, electronics, fundamental of power systems and power electronics. Basic concepts of system analysis are also suggested.

Introduction. Pole mounted and pad mounted secondary substations. Design Criteria. Typical electromechanical schemes. Protections and switchgears. Cooling. Noise. Grounding system.

Reactive power compensation in MV and LV (3h lectures,2h classwork)
Motivations for reactive power compensation: loss reduction and voltage regulation. Capacitors, static VAr compensators and other devices for reactive power compensation. Optimal design of MV and LV capacitor banks. Power quality issues related to capacitor banks. Swithgear and protections for capacitor banks.

Protection systems (8h lectures; 2h classwork)
Generalities. Fault classification. Characteristics of the protection system. Protection systems against overload, overvoltage and short circuits. Protection relays: definitions, characteristics, typologies and classifications. Functional and building characteristics. Design of the protection system: coordination among relays. Current and voltage transformers. Example of application in typical cases: protection of transformers, generators, busbar and lines.

Arc interruption theory (8h lectures, 2h classwork)
Electric arc. Methods of arc interruption. High resistance method (DC interruption) and zero interruption method (AC). Interruption of short circuit currents and capacitor currents and Circuit breakers for transmission and distribution systems. Sectionalizers. Fuses.

Distributed Generation (3h lectures; 2h classwork)
Asynchronous machines, protection, starting and control of motors.
Power generation with synchronous machines. Steady state models. Operation Under Load, The Rotating Magnetic Field, Stator–Rotor Interaction, The Phasor Diagram and the Single-Phase Equivalent Circuit, Practical Considerations, Power Exchanges, Generators and Motors, 357

SMART GRID (10h lectures; 5h classwork)
Definition. Integration of Renewable energy sources. Demand Side Integration. Communication System for Smartgrid. Innovative protection systems in Smartgrid (self-healing). Planning and operation of Smartgrid. National and international standards and regulation.

Teaching Methods

43 hours of lectures and 17 hours of classwork with the usage of power system software
Methods and techniques for on-site interaction with students:
1) Dialogue and discussion stimulated by teacher questions
2) Email and website communication
3) Communication with on request face to face meetings
Interaction between methods and techniques for teaching and learning:
Classical teaching will be completed with the exploitation of audio-visual supports, computers and tablets.

Verification of learning

One or more assessment tests with theoretical and practical questions are done during the course. The participation to the test is allowed only to all students. Tests will be used by students for self-assessment; not sufficient results can be recovered at the final examination. Minimum grade (18/30) is given when the level reached is basic, maximum grade (30/30) when the results are outstanding and all abilities achieved. Final examination is in the form of oral examination for the assessment of the communication skills and technical knowledge on topics not covered during the previous tests. For students that decided not to participate to tests the final examination aims also at assessing the applying knowledge and understanding skills with specific written tests and exercises.

More Information

Lecture notes and slides are provided, as well as exercises and test given in past years. Lectures are given with the aid of power point slides and tablets. If tablet is used, the lecture is delivered to students as pdf at the end. Free or educational software for power systems studies are also provided.
Workers can ask for on-line tests and exercises on specific topics with the aid of a tutor or the teacher; in this case Skype will be the used platform for communication.
