6 FAQs about [Energy storage frequency regulation ancillary service policy]
What are ancillary services?
The study object of ancillary services is limited to PFR, while ancillary services also include secondary frequency regulation, automatic generation control (AGC), peak shaving, reactive power regulation, standby, black start, etc. Therefore, further study on secondary frequency regulation and other important service functions could be carried out.
Can battery storage provide ancillary services?
However, battery storage-based resources can provide much faster regulation service than conventional generators. Therefore, the compensation mechanism must appropriately value the performance characteristics of diferent resources. This will incentivise greater deployment of battery storage technology in providing ancillary services.
Do pumped storage plants provide auxiliary services for power grids?
Pumped storage plants (PSPs) could provide important auxiliary services for power grids, and frequency regulation is a crucial function. Quantitative evaluation of primary frequency regulation (PFR) performance is a key issue for benefits of auxiliary services of PSPs and operation and management of power grid.
What is frequency regulation service?
In many ancillary service markets, frequency regulation service is procured as a single product that includes both frequency regulation up and frequency regulation down services. For instance, in Denmark, Italy and Spain system operators procure such a unified frequency regulation service under FRR requirements (IRENA, 2017).
How are ancillary services based on economic factors?
Five important indexes are selected based on China and the US electricity markets. Economic factors in ancillary services are studied based on physical features. Hydraulic characteristics are studied in seconds considering various schemes. The work could promote the coordination between power plants and power grids.
Does pumped storage contribute to ancillary services?
From the perspective of electricity markets, pumped storage plays a key role in ancillary services, and the contribution of ancillary services to VRE integration has become an important topic for the feasibility of highly renewable power systems [ 7, 8 ]. There are many international projects on the modeling and service value of PSPs.
