POWER ELECTRONICS SIMULATION FOR GRID APPLICATION AND TRANSPORTATION ELECTRIFICATION

Abstract

The global shift toward renewable energy and electrified transportation is transforming modernpower systems, with power electronics playing a critical role in enabling efficient energy conversion and control. However, their nonlinear dynamics, high-speed switching, and complex controls requirements brings challenges, particularly when integrated into larger networks. This thesis addresses these challenges by leveraging advanced simulation and real-time testing techniques. Using tools such as MATLAB/Simulink, PLECS, Typhoon HIL, and OPAL-RT, it develops accurate models of power converters, capturing key phenomena like switching dynamics, losses, and fault responses. These models are validated through Hardware-in-the-Loop (HIL) and Controller-in-the- Loop (CHIL) simulations, enabling rigorous testing of control algorithms and system interactions under realistic conditions. The result emphasizes the values value of combining simulation and real-time testing to design power systems that are efficient, reliable, and robust. By addressing key challenges and advancing tools for modeling, this work supports the seamless integration of renewable energy and transportation electrification, contributing to a more sustainable and resilient energy future.
