LEARNING OUTCOMES

During the course proper design aspects of protection systems are analysed. The course is focues on the problems of integration between protection, control and telecommunications in light of the spread of distributed generation and the evolution of electrical distribution systems.

AIMS AND LEARNING OUTCOMES

The course aims to present the systemic, methodological and technological aspects for the protection of electrical energy systems, with particular regard to the new scenario of widespread and renewable generation.

Attendance and active participation in the proposed training activities (lectures and laboratory activities) and individual study will allow the student to

- know in depth the main aspects of distributed generation;
- know the mechanisms of energy production from renewable sources;

- identify the main differences in the design of distribution networks and related protections, in particular as regards: degree of reliability required, maximum intervention speed, appropriate degree of selectivity
- apply the knowledge for the correct modeling of electrical systems in the presence of power converters;
- acquire a correct terminology for the aspects of integration between protection and control, of telecommunications also in the light of the diffusion of traditional and renewable distributed generation and of the evolution of electrical distribution and industrial systems, with particular attention to MicroGrids, to storage systems , and to the direct control of the load for the purposes of protection and energy efficiency.

TEACHING METHODS

Combination of traditional lectures (40 hours) and classroom discussion of specific projects (20 hours). 

SYLLABUS/CONTENT

The course deals with various issues on the protection and management of electrical systems, in particular:

• Architecture of distribution network automation systems (DMS - Distribution Management Systhem): analysis of the new monitoring and control functions of distribution networks in the presence of renewable generation.
• Wind and photovoltaic electricity generation. Sizing and modeling
• Protection of electrical systems: detailed analysis of the protections in electrical systems (line protections, busbar protections, generator protections, transformer protections, reactor protections, back-up protections and protection systems for large areas).
•  Analysis of grid-following conversion systems applied to renewable production systems
• Analysis of the IEC 61850 standard "Communication networks and systems in substation".
• Protection of distribution networks: integration between protection and control in the light of the diffusion of traditional and renewable distributed generation and interconnection systems.
• Modeling of storage systems: analysis of storage systems for the control of MicroGrids with a strong presence of renewable sources.
• Load management: the role of the electrical load in the new SmartGrid scenario.
• Aspects of power system modeling on board ship
