This is the final report of IEA PVPS Task 14, focusing on the potential of distributed solar photovoltaic (PV) and PV hybrid systems in providing frequency-related grid services. This comprehensive report underscores the growing importance of renewable energy sources in maintaining stable and secure electrical power systems as the reliance on conventional fossil-fuelled power plants diminishes.
The report highlights the necessity for solar PV systems, along with other inverter-coupled generators such as wind turbines and storage units, to take on additional grid support tasks traditionally managed by conventional power plants. These responsibilities are critical to ensure the stable operation of electrical power systems worldwide.
Key Takeaways:
- PV systems already have the technical capabilities to provide various frequency-related grid services.
- The transition from grid-following to grid-forming operation will enable PV systems to provide the full set of frequency services, similar to those provided by rotating generators today.
- Clearly and precisely stipulated requirements, as well as standardized testing procedures, are key for comparing their contributions to frequency-related services.
