Models and scenarios for energy planning
Corso di Laurea Magistrale in Petroleum Engineering (Ingegneria Del Petrolio) - Torino
The course is inter-disciplinary in nature, being culturally located at the crossroads between economics and engineering.
The course focuses on the modeling of the dynamics of energy markets on medium-long terms under a complex set of constraints. This modeling is crucial today for the planning of sustainable energy strategies at regional, national and international level.
The course starts presenting the output of the World Energy Model (WEM), presented yearly in the World Energy Outlook (WEO) by the International Energy Agency (IEA), consisting mainly of emissions to the environment (CO2) and investments. These follow from a set of assumptions (e.g., governments policies related to energy sector, technological advances, economic and population growth) made in input and collected in so-called scenarios, which are also carefully discussed.
The different possible approaches to the complex challenge of the development of a model connecting the input to the output are then presented: top-down vs. bottom-up ("engineering-economic" models), partial vs. global equilibrium models, with particular attention devoted to the bottom-up, partial equilibrium MARKAL - TIMES family of models. The WEM is considered in depth, highlighting the assumptions in input, the interconnections between energy demand, energy supply and technologies. An introduction to the mathematical methods adopted (e.g. linear and non-linear programming, stochastic and Monte Carlo methods), which are at the core of the solution of this constrained optimization problem is provided, as well as an assessment of the propagation of uncertainties from input to output.
The output of the WEM is analyzed, considering energy balances at regional level and also specific energy markets (e.g, the oil market). The students are grouped in small teams and asked to report on the latter.
In parallel with these theoretical developments, the students have the opportunity to learn with a hands-on approach the use of a freeware for energy modeling, called EnergyPLAN, and to apply it to the analysis of a case study.
Risultati di apprendimento attesi
Through this course the students are expected to acquire a good knowledge of:
• The rationale behind energy models at local/regional/world level,
• The input needed for energy models (MARKAL – TIMES and in particular the WEM), and the relative output,
• The main algorithms adopted for the solution of the constrained optimization problems hidden in the models,
• The main scenarios considered in the WEO,
• The outlook of the main energy markets for the next few decades.
The students will also acquire the ability:
• To use the software EnergyPLAN for the analysis of a regional energy balance,
• To work in a small team, analyzing the outlook of specific energy markets and taking advantage of the exchange of ideas with their peers,
To present the output of the team work to the rest of the class and to discuss it interactively.
