Description of Achievement and Assessment Methods

During the final examination (90 min), the students shall proof by solving problems that basic concepts, power electronic actuators, working/energy conversion principles, modeling and control techniques for renewable energy systems were understood and could be reproduced. The examination is a closed-book exam; solely an unchanged formulary (provided by the lecturers) is admissible

Prerequisites (recommended)

Basic knowledge of :
• linear algebra,
• differential equations,
• complex phasor theory
• Laplace / Fourier transformation
• electrical machines (desirable)
• power electronics (desirable)
• control engineering (desirable)

After successful participation of this module you are capable of:
a) "Power Electronics for Renewable Energy Systems":
• Understanding, analyzing and designing power electronic circuits for regenerative energy systems
• Understanding protective mechanisms of power electronic circuits
• remembering the most important semiconductors, their parameters and their parasitic effects

b) "Modeling and Control of Renewable Energy Systems ":
• analyzing the working and energy conversion principle(s) of renewable energy systems
• understanding and deriving of state-space models of components of renewable energy systems
• understanding, applying and implementing control methods for machine- and grid-side components
• understanding, applying and implementing operation management methods for renewable energy systems

Teaching and Learning Methods

Classroom (60 hours):
The module consists of two lectures (sub-modules à 2SWS). The content is presented during lectures by presentations, talks, tutorials, interactive discussions, demonstrations and black/white board sessions.

Self-Study (90 Stunden):
• Preparation and review of the lectures
• Solving problems (solutions provided)
• preparation for examination

Content

The module "Renewable Energy Systems: Power Electronics, Modeling and Control" deals with working principles, modeling and control of and power electronics for renewable energy systems (e.g. photovoltaic or wind turbine systems). It consists of two of two sub-modules:
- "Power Electronics for Renewable Energy Systems" (2SWS) and
- "Modeling and Control of Renewable Energy Systems" (2SWS)
The contents of both sub-modules are:
- "Power Electronics for Renewable Energy Systems":
• Active and passive components for power electronics, driving circuits,
• Basic circuits for grid integration
• Power electronics for photovoltaic and wind energy
• Power electronics for battery storage systems
• Regulations and standards
- "Modeling and Control of Renewable Energy Systems":
• Working and energy conversion principles of renewable energy systems
• Nonlinear state-space modeling of components (e.g. turbine, generators, converters, dc-link, grid filters) of renewable energy systems
• Control of machine- and grid-side components (e.g. speed, current, voltage and power control) of renewable energy systems
• Grid synchronization and optimal operation of renewable energy systems
