OVERVIEW

The course aims to present with systemic and cross-disciplinary, methodological and technological aspects for the protection of electrical energy systems , with particular regard to new widespread and renewable generation scenario, including microgrids , the load control ( demand response ) and to storage systems.
 

AIMS AND CONTENT

LEARNING OUTCOMES

During the course proper design aspects of protection systems are analysed.In addition, distributed generation models will be developed such as wind farms, photovoltaic plants and storage systems. The course is focused 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

The course includes theoretical lessons, seminars and exercises with the development of application examples. The lessons are complemented by practical exercises and seminars on topical problems with the presentation of "test cases" (The IEC 61850 standard, Demand Side Management). Technical visits to test facilities and distribution networks where there are accumulation systems and control and protection systems are planned.

Exercises are planned in the ShIL laboratory where storage systems, programmable converters and real-time simulator are present.

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

EXAMS

EXAM DESCRIPTION

The exam consists of a written and an oral part.

The written part is represented by a computer-based work on modeling or dimensioning aspects of electrical systems with distributed generation. The paper must be delivered at least one week before the oral exam accompanied by an explanatory report. The verification consists of an oral interview aimed at highlighting both the acquisition of the fundamental contents presented during the course and the application skills in solving operational problems. The developed paper will also be discussed in the interview.

ASSESSMENT METHODS

Details on how to prepare for the homework and on the degree of detail of each topic will be given during the lessons.
The homework will verify the effective acquisition of basic knowledge on some methodologies for modelling and sizing renewable production systems. The problems and open questions will allow the assessment of the ability to apply knowledge in practical situations that may occur in the laboratory. The student must be able to connect and integrate the knowledge learned during the laboratory activities with that provided during the frontal lessons.

The oral exam will mainly focus on the topics covered during the frontal lectures and will have the purpose of evaluating not only if the student has reached an adequate level of knowledge, but if he has acquired the ability to critically analyze the plant and system engineering problems that will be posted in the course of the exam.
