227-0250-00L	Power Semiconductor Packaging	W	6 KP	2V + 2U	U. Grossner, I. Kovacevic
Kurzbeschreibung	Power semiconductor devices are the core of today's energy efficient electronics. However, without adequate integration into power electronic systems, they remain useless. This is achieved by providing application-tailored modules. The development of power modules is reviewed from basic design and material considerations, with special emphasis on simulation and characterization techniques.
Lernziel	The goal of this course is developing an understanding of modern power module concepts, from materials to design and simulation. After following the course, the student will know the basic functionality of a power module, and is able to describe the performance and reliability related building blocks of the module design. Furthermore, the student will have an understanding of current and future developments in power packaging.
Skript	Will be distributed at lectures and be made available at ILIAS.
Literatur	The course follows a collection of different books; more details are being listed in the script.
Voraussetzungen / Besonderes	Ideally, students have successfully attended "Power Semiconductor" (227-0156-00).
227-0528-00L	Power System Dynamics, Control and Operation	W	6 KP	4G	G. Hug
Kurzbeschreibung	The electric power system is a system that is never in steady state due to constant changes in load and generation inputs. This course is dedicated to the dynamical properties of the electric power grid including how the system state is estimated, generation/load balance is ensured by frequency control and how the system reacts in case of faults in the system. The course includes two excursions.
Lernziel	The learning objectives of the course are to understand and be able to apply the dynamic modeling of power systems, to compute and discuss the actions of generators based on frequency control, to describe the workings of a synchronous machine and the implications on the grid, to describe and apply state estimation procedures, to discuss the IT infrastructure and protection algorithms in power systems.
Inhalt	The electric power system is a system that is never in steady state due to constant changes in load and generation inputs. Consequently, the monitoring and operation of the electric power grid is a challenging task. The course starts with the introduction of general operational procedures and the discussion of state estimation which is an important tool to observe the state of the grid. The course is then dedicated to the modeling and studying of the dynamical properties of the electric power grid. Frequency control which ensures the generation/load balance in real time is the basis for real-time control and is presented in depth. For the analysis of how the system detects and reacts dynamically in fault situations, protection and dynamic models for synchronous machines are introduced.
Skript	Lecture notes. WWW pages.
227-0530-00L	Optimization in Energy Systems	W	6 KP	4G	G. Hug
Kurzbeschreibung	The course covers various aspects of optimization with a focus on applications to energy networks and scheduling of hydro power. Throughout the course, concepts from optimization theory are introduced followed by practical applications of the discussed approaches.
Lernziel	After this class, the students should have a good handle on how to approach a research question which involves optimization and implement and solve the resulting optimization problem by choosing appropriate tools.
Inhalt	In our everyday’s life, we always try to take the decision which results in the best outcome. But how do we know what the best outcome will be? What are the actions leading to this optimal outcome? What are the constraints? These questions also have to be answered when controlling a system such as energy systems. Optimization theory provides the opportunity to find the answers by using mathematical formulation and solution of an optimization problem. The course covers various aspects of optimization with a focus on applications to energy networks. Throughout the course, concepts from optimization theory are introduced followed by practical applications of the discussed approaches. The applications are focused on 1) the Optimal Power Flow problem which is formulated and solved to find optimal device settings in the electric power grid and 2) the scheduling problem of hydro power plants which in many countries, including Switzerland, dominate the electric power generation. On the theoretical side, the formulation and solving of unconstrained and constrained optimization problems, multi-time step optimization, stochastic optimization including probabilistic constraints and decomposed optimization (Lagrangian and Benders decomposition) are discussed.
