While the dual-port control approach offers several advantages, there are potential challenges and limitations that need to be addressed:
Scalability: As the complexity of the grid increases with more terminals and AC grids, the scalability of the control scheme may become a challenge. Ensuring that the control algorithms can effectively scale up to larger systems without compromising performance is essential.
Computational Complexity: Handling multiple terminals and grids can increase the computational complexity of the control scheme. Efficient algorithms and real-time processing capabilities are required to manage the increased computational load.
Practical Implementation: Implementing the dual-port control scheme in a real-world system may pose challenges in terms of hardware compatibility, integration with existing infrastructure, and regulatory compliance. Practical considerations such as cost, hardware limitations, and system interoperability need to be addressed.
Robustness: The dual-port approach must be robust against uncertainties, variations in operating conditions, and external disturbances. Robust control strategies and fault-tolerant mechanisms need to be integrated to ensure the stability and reliability of the system.
