Energy Systems: Hardware and Control

 

"Energy Systems: Hardware and Control" is a module of the M.Sc. course "Renewable Energy Engineering and Management", elective track "Energy Systems Technology".

 

Contents

This module consists of two parts:

  A) Hardware of high-power electronics. This part is lectured by PD Dr. Rüdiger Quay from Fraunhofer IAF and Prof. Dr. Bruno Burger from Fraunhofer ISE.

  B) Systems Theory and Feedback Control. This part is lectured by Prof. Dr. Moritz Diehl (moritz.diehl (at) imtek.uni-freiburg.de) and Dr. Gianluca Frison (gianluca.frison (at) imtek.uni-freiburg.de) from University of Freiburg, Systems Control and Optimization Laboratory.

 

In Part A of this module building hardware aspects of power electronics will be introduced. The course starts with the fundamentals and concepts of power devices and circuits. It comprises three aspects: fundamental power conversion-concepts with focus on DC-DC and –AC conversion, more complex power circuitry, and actual power conversion systems. At the interface of modern electronics, circuit design, and control theory, advanced analysis and characterisation techniques are introduced in order to bridge the gap from modern power conversion to the understanding of systems and network systems with all aspects of power conversion. Students will carry out study examples using the simulation software QUCS.


In Part B of this module, students are introduced to the design and analysis of feedback control systems. We start with regarding general ordinary differential equations (ODE) and then focus on linear time invariant systems in continuous time. Conditions for stability are discussed, and performance measures for feedback control systems defined. We then discuss state space control design in more detail, covering topics such as Luenberger Observer, Kalman Filter, the Linear Quadratic Regulator (LQR) in both continuous and discrete time, and an introduction to Model Predictive Control (MPC).
