The adoption of the dual-port control scheme in future power systems with high penetration of renewable energy sources and power electronic interfaces can have significant impacts on design and operation:
Enhanced Grid Stability: The dual-port control scheme can improve grid stability by providing grid-forming capabilities on both the AC and DC sides. This can help maintain voltage and frequency stability, especially in systems with high renewable energy integration.
Increased Flexibility: The dual-port approach allows for seamless integration of multiple AC grids and HVDC systems, enabling greater flexibility in power flow management and system operation. This flexibility is crucial for accommodating variable renewable generation.
Optimized Energy Exchange: By forming stable voltage on both AC and DC sides simultaneously, the dual-port control scheme can optimize energy exchange between different grids and terminals. This can lead to more efficient utilization of renewable energy resources.
Grid Resilience: The dual-port control scheme's ability to handle complex grid topologies and fault scenarios enhances grid resilience. It can support islanded operation, fault ride-through capabilities, and rapid system restoration, improving overall grid reliability.
Integration of Energy Storage: The dual-port control scheme can facilitate the integration of energy storage systems into the grid, enabling better management of intermittent renewable generation and enhancing grid stability during fluctuations.
In conclusion, the dual-port control scheme offers a promising solution for future power systems, addressing the challenges of renewable energy integration, grid stability, and system flexibility. Its adoption can pave the way for a more sustainable and resilient energy infrastructure.
