Grid Connected Voltage Source Converter with DC Voltage Control

n this project, I took on the challenge of replicating the Grid Connected Voltage Source Converter with a DC Voltage Bus Controller example from the textbook "Voltage-Sourced Converters in Power Systems" by Amirnaser Yazdani and Reza Iravani. By using the power of Simulink's intuitive graphical environment, I was able to visualize and simulate the system successfully.

One of the key highlights of this project was designing the controllers for the phase-locked loop and the DC bus. It required a deep understanding of some principles. such as the ability to plot Bode plots for closed-loop systems. By carefully analyzing the plots, I was able to add poles or zeroes strategically, enabling me to optimize the system's performance and achieve the best response possible. Furthermore, I successfully modeled the currents and voltages of the system in the dq frame which simplifies control algorithms, improves dynamic response, and reduces cross-coupling effects in motor control systems.
