Overview of the different renewable energy sources and their potentials Photovoltaic, Wind power etc.

---

Principles of grid-connected as well as of idle solar inverters for photovoltaic systems
Physics of the solar cell
Inverter topologies
System architectures: central, string and module inverters
Control methods: PWM, MPP tracking etc.

---

Principles of wind turbines
double-fed induction machine
Plant with synchronous machine
Wind power-specific control algorithms

The students will be able to explain electronic and electromagnetic structures, topologies and control methods of various renewable energy generation systems (photovoltaic, wind, etc.).
The students possess the ability to dissect the entire plant-specific system technology into essential subsections, to develop or to project individual aspects and thus to carry out individual steps of a synthesis.
The relationship to reality, in particular with regard to new regulatory, normative framework conditions that accompany the energy transition, is being established. This enables the student to describe the actuators as part of an intelligent network in the superordinate context in order to later select or develop the correct actuators.

---

The students become acquainted with methods for the dynamic description and regulation of renewable energy generation plants and thereby obtain decision-making authority.
The students have experience in handling power electronics, drives, classical measuring devices and are able to model actuators with a simulation tool.
Students have the ability to understand, dimension and regulate electrical actuators for renewable energy generation.

In a first experiment, an inverter for a photovoltaic system is modeled as an example and simulated with a simulation tool. Special attention is paid to the plant-specific regulatory procedures (MPP tracking, etc.). Thereafter, a commercial inverter is measured and analyzed.

---

In a second experiment, a double-fed induction machine including converters is being investigated as an actuator for wind turbines.

Students can handle a standard commercial modeling and simulation tool.
The students understand the working behavior of power electronic actuators.
The students can solve tasks in a small team.
They can analyze measurement results and gain insights into the measurement object.
They can model and simulate a real system.
