Digitaler Zwilling & KI-basierte Regelung

Description of work:
Modern electrical energy conversion systems are becoming more intelligent, with the ability to exchange energy between energy storage, electrical grid, charging station and consumer – this project considers bidirectional power electronics, which allows us to control the flow of energy from source to consumer, as well as in the opposite direction.
The project aim is to compare the performance and efficiency of three-phase bidirectional schemes of different topologies. These schemes are prospective and are widely used in energy storage systems, charging stations, industrial sources, etc. The work should also analyze the schemes for the optimal application of GaN or SiC devices. Method of investigation – multidomain simulation using Matlab/Simulink and Plecs.
Tasks & Goals:
• Familiarization & literature search (10%)
• Calculations, design and components selection of power electronics (20%)
• Design and implementation the control system (15%)
• Simulation in different modes, discovering performance and efficiency of the schemes (40%)
• Written thesis & presentation (15%)
Benefits for student:
• Experience in simulation multidomain
system-level models
• Familiarization with a performance of
prospective bidirectional schemes, which
used in energy storage systems, charging
stations, industrial sources, etc
• Improving Matlab and Plecs skills
Previous Knowledge:
• Power Electronics
• Control System Theory
• Matlab/Simulink/Simscape

Modern electrical energy conversion systems are becoming more intelligent, with the ability to exchange energy between energy storage, electrical grid, charging station and consumer – this project considers bidirectional power electronics, which allows us to control the flow of energy from source to consumer, as well as in the opposite direction.
In this project, one of the prospective one-phase bidirectional schemes is considered, which is used in energy storage systems, charging stations, industrial sources, etc. The project aim is to develop a multidomain system-level model of one-phase bidirectional electric converter in the closed-loop regulation by control system. Loss calculation will be done using Plecs.

Description of work:
Hardware-in-the-Loop (HIL) testing is one of the modern methods to investigate behavior of physical equipment virtually. In this project, the digital twin of power electronics of AC/DC converter in PFC stage is considered in HIL mode. This digital twin is deployed in the dSpace Microlabbox hardware and run in real-time mode. This approach allows us to simulate the operation of power electronics for an external control system. The control system is deployed on the TI control board, and it forms a closed control loop together with a digital twin of power
electronics.
The project aim is to develop closed control loop system running in real-time mode and consisting of power electronics (represented by digital twin on Microlabbox hardware) and control system (represented by TI control board).
Tasks & Goals:
• Familiarization & literature search (10%)
• Calculations, design and components selection of power electronics (10%)
• Design and simulation the control system with the model of power electronics (10%)
• Deployment control system on TI control board (programming directly from Simulink) (10%)
• Deployment the digital twin of power electronics on Microlabbox (10%)
• Assembly setup in the closed-loop system and test (35%)
