The main benefits of using power converter-fed synchronous machines (CFSMs) in pumped hydroelectric systems include:
- Operational Flexibility:
- CFSMs facilitate variable-speed operations, allowing for enhanced performance in both generating and pumping modes. This flexibility is crucial for supporting grid stability, particularly with the integration of intermittent renewable energy sources.
- They can operate as synchronous condensers or static synchronous compensator modes, providing additional grid support services.
- Cost-Effective Upgrades:
- Many existing hydroelectric facilities already use synchronous machines, making CFSMs a cost-effective choice for upgrades. They leverage existing equipment, thereby reducing the need for new infrastructure.
- Reduced Startup Time:
- CFSMs minimize startup times in pumping mode without the need for dewatering. This reduces wasted time and enhances overall system responsiveness and reliability.
- Grid Support and Energy Storage:
- The ability to provide quick responses to load variations supports grid stability and compensates for the variability of renewable energy sources. Pumped hydroelectric systems, coupled with CFSMs, play a critical role in energy storage and peaking power regulation.
These benefits collectively make CFSMs an attractive technology for modernizing hydropower infrastructure to meet the challenges of integrating renewable energy sources into the grid.
