PERIOD: SETTEMBER 2019 The course deals with the main aspects related to the characterisation, evaluation and planning of multi-generation energy systems for small-scale (< 1 MW) applications. The adoption of multi-generation plants suitably designed and managed can outperform, from an energy saving and economic point of view, the traditional systems in which various forms of energy (e.g., electricity, heat and cooling) are produced or purchased separately. The focus is on assessing the performance of distributed cogeneration, such as microturbines and internal combustion engines, coupled to various equipment for heating and cooling power production in trigeneration and multi-generation systems. Specific aspects concern the environmental impact of the multi-energy solutions, the interactions with external energy networks (e.g., electricity, gas, district heating and cooling), and the economic assessment of the solutions. In particular, new techniques and indicators for the characterisation, evaluation and planning of multi-generation plants are introduced and discussed. All course activities will be in English.

The lecturers address the basic aspects and provide an overall view on the characteristics and applications of multi-energy systems in the evolving context of the energy transition. The knowledge and skills graduated in any engineering curricula, together with a specific interest towards the innovative aspects of the energy system evolution, are considered to be sufficient.

 Introduction to cogeneration, trigeneration, and multi-generation  Components, models and characterisation of small-scale cogeneration plants for distributed generation  Components, models and characterisation of small-scale generation plants for cooling and heating production  Comprehensive matrix-based characterisation of multi-energy systems  Planning aspects for cogeneration and trigeneration plants  Energy saving performance indicators for multi-energy systems  Global and local environmental impact of multi-energy systems and performance indicators  Economic evaluation of cogeneration and trigeneration plants  Power system support services from multi—energy systems  Case study applications and classworks Exam: The exam is an individual one-hour written test with multiple responses, in which only one response is correct for each question. Some questions refer to the basic concepts addressed in the multi-energy area. Other questions require calculations to identify the correct result, in order to check quantitative aspects of multi-energy applications. The student may use any material during the test, with the exception of Internet connections, phone connections or contacts with other persons through any mean. The exam will start at the beginning of the morning, and the final results will be provided by the exam Commission before the end of the same morning. The “pass” is obtained if the score is at least 50% of the maximum score. The “merit” is obtained if the score exceeds 90% of the maximum score. If the score obtained is lower than 50% of the maximum score, the exam is not passed, but the student will have the possibility of passing the exam in a successive period by preparing a report that contains the correct solutions of three exercises indicated by the professor responsible of the course. In this case, the report will have to be discussed with the exam Commission. The preparation and presentation of the report are up to the willingness of the student, there is no limit time to provide the report, and there will be no reminders sent by the professor responsible of the course.

Course structure The duration of the course is 25 hours. The course is delivered in an intensive way during one week. The lectures start on Monday morning at 10:00 am and are concluded on Thursday afternoon. The final test is on Friday morning. The lectures are delivered as presentations in six half-day periods of 3 hours or 3 hours and 30 minutes each. In two periods there are classworks in which numerical exercises are solved in groups of maximum two students, with the use of the computer (a personal computer will be available in the laboratory for each student group; the use of a laptop brought by the student is allowed).

Reading materials The course material is provided by the lecturers before each lecture. There is no commercial books that covers the entire set of topics addressed by the lecturers. The lecturers also provide a list of relevant references referring to the various topics. Some contents may be found in the following book and book chapters: - P. Mancarella and G. Chicco, Distributed multi-generation systems. Energy models and analyses, Nova Science Publishers, Hauppauge, NY, 2009. - P.
