Energy networks represent a key part of energy infrastructure, ensuring the transportation and distribution of energy and fuel when available far from the end-users. Typical examples are: a) Gas pipelines representing the main way to transport gas internationally and to distribute it, at different levels, within countries b) Electricity grids (transmission and distribution) which is a critical point for the exploitation of renewable energy sources (RES), representing a core issue of the energy transition c)Thermal networks for district heating and cooling, playing a crucial role to provide heat produced by efficiency plants, renewable sources, or waste heat. to houses in urban areas Proper operation and design of the energy networks allow significantly increasing the efficiency of the energy systems and enabling the exploitation of low grade and fluctuating energy. Furthermore, a smart exploitation of the conversion technologies (e.g. electricity to gas, electricity to heat/cool, gas to power, etc.) represents a unique opportunity to expand the energy system flexibility. For these reasons there is great interest in the scientific and industrial community about the energy network topic. This course focuses on the major types of energy networks and aims to provide the student with knowledge about energy networks as well as the ability to analyze and model electric, gas, and thermal networks. A technical description of these assets and detailed information on modeling approaches is provided. Current and future trends are described, including consideration on the interaction between the different types of networks. A significant part of the course is devoted to the development of a practical design project.
At the end of this course, students are expected: 1) to acquire detailed knowledge about electricity, gas and heat networks, including design and operation. 2) to become aware of the trend (and the challenges) of the energy networks in relation to the evolution of the technologies adopted for the energy production 3) to be able to simulate physical behaviour of energy networks. Specifically: a) As concern thermal networks, students are expected to learn how to solve the fluid dynamic problem considering a one-dimensional approach as well as to know the techniques for solving the thermal problem, applying them to practical cases. b) For gas networks, the student will learn how to extend the momentum and energy equations to compressible fluids such as natural gas and how to model complex fuel mixtures that can be transported in gas pipelines with main focus on hydrogen and biomethane. c) For electricity networks the student will learn the structure and the role they play in energy systems with an outlook on the interchanges with other commodities as well as the mathematical modelling of the network in steady state along with the main operational requirements (frequency and voltage). The emerging challenges (RES, storage, P2x) are introduces in the framework of the energy trilemma 8sustainability, security equity)
Engineering thermodynamics and heat transfer. Computational language.
Introduction to the main energy trades. Thermal networks: current situation worldwide and trends. Technical characteristics of thermal networks. The main components: heat sources, transport and distribution pipelines, thermal substations, pumping systems, connected buildings and thermal storages. From the first to the fourth generation district heating. Fluid dynamic calculation: from 3D to 1D. Solution of the fluid flow and thermal problem and application to a network (work to be developed in groups). Analysis of real networks. Gas networks: technical description of gas networks from transmission to distribution level. Pipeline description, gas quality and interchangebility. Momentum and energy equation, adaptation for the modelling of gas pipelines and networks. Modelling of non-pipe elements (i.e. compressors, reduction station). Simulation of gas networks with multiple fuel injection. Electricity networks: structure of electrical energy systems (generation, transmission, distribution and utilization). Definitions of adequacy and security. The operation of electricity network in normal state: power frequency regulation and voltage control. The steady state operation of electricity networks: power flow equations (AC and linearized DC, backward and forward sweep), solution techniques. Application of real systems with dedicated graphical SW. Electricity networks in energy transition: penetration of renewables and inertia problems, storage e multi commodity transformation of electricity. Multiscale electricity networks from global interconnections to smart grids. The impacts of networks in electricity markets.
The course is organized with theoretical lessons and practices in lab. During lessons the technical aspects related with the energy networks and modeling techniques will be developed. A relevant part of the course is devoted to project team working using proper language software for the design and simulation of energy networks.
Teaching material provided by the teachers
Lecture notes;
Exam: Written test; Group project;
The final mark is composed by the written test for 24/30 and for 6/30 by the group project. The written test is composed of questions, both open and multiple choice (in the case of multiple choice, no penalties is applied for wrong answers). This part aims at evaluating the specific knowledge of the student concerning the technical aspects related with energy networks as well as the ability of the student to apply the numerical modeling techniques. The group project is specifically designed in order to make the student familiar with the application of the modeling techniques. The specific contribution of students is assessed through proper questions in the written test which are tailored on each specific project. During the written exam is not possible to use any teaching material. The duration of the exam is approx. 90 min. There is no specific deadline for submitting the reports on the group project.
In addition to the message sent by the online system, students with disabilities or Specific Learning Disorders (SLD) are invited to directly inform the professor in charge of the course about the special arrangements for the exam that have been agreed with the Special Needs Unit. The professor has to be informed at least one week before the beginning of the examination session in order to provide students with the most suitable arrangements for each specific type of exam.
