Advanced Control of Variable Speed HydropowerPlant (VSHP) for Improved Operation

Main objective
To develop optimal controllers for improved operation of VSHP
Specific objectives
Implement a state of art modelling framework for a VSHP system with conventional control systems. This includes turbine, waterway, generator, and necessary additional equipment.
Develop a model based advanced control of VSHP system. Test the controller under the presence of parametric uncertainty
Develop a new control system that incorporates uncertainties on certain parameters and include stochastic controllers
Investigate the coordination possibilities with multiple VSHP systems in the same waterway for optimal operations
Study the grid impact on VSHP after implementing the advanced control. This might be adjusted based on the project progress later on.

Expected Outcomes:
The expected outcomes encompass the development of a comprehensive Variable Speed Hydro Power (VSHP) system model, including accurate representations of the turbine, waterway, generator, converter and associated equipment. The advanced control system is anticipated to successfully identify and adapt to the system’s dynamics, demonstrating robustness under parametric uncertainties. Additionally, the control system will be enhanced to incorporate uncertainties and employ stochastic controllers, ensuring stable operation in the face of unpredictable variations. Investigation into the coordination of multiple VSHP systems in the same waterway aims to optimize operations through insights into power sharing and load balancing. The study will conclude with a thorough analysis of the grid impact post-advanced control, with adjusted strategies to optimize interaction and align with regulatory standards for efficient energy integration.

About Myself,
At 29, I’m a female associated with the fascinating world of electrical engineering, driven by an unyielding passion for learning. Hailing from a middle-class background, my journey has always been fueled by dreams of independence and the desire to make my parents proud. In the tech world, I enjoy taking on challenges to grow my knowledge and skills. But beyond all the wires and circuits, I also find joy in poetry and fiction. Nature is my happy place, where I recharge and enjoy quiet moments. I am not afraid of a little excitement! Bungee jumping and thrill sports are my kind of fun. I also have a soft spot for music, adding a bit of melody to my diverse interests. While I think there might be something supernatural out there, I strongly believe in the power of hard work and determination. With a mosaic of interests and an unwavering commitment to personal and professional growth, I am a narrator of my own story—a story that intertwines passion, intellect, and a resolute sense of purpose.”
