Outdoor Energy Storage Battery Reliability

Why are battery energy storage systems important for BPS reliability?

Along with this increase in IBR, primarily from the addition of a large contribution of renewable resources (e.g., wind, solar), there has been an increase in the application of battery energy storage systems (BESS) on the BPS. BESS have the ability to complement IBRs by providing some of the ERS that are important to maintain BPS reliability.

What is a battery energy storage system?

battery energy storage system (BESS) is a term used to describe the entire system, including the battery energy storage device along with any ancillary motors/pumps, power electronics, control electronics, and packaging. Since all electrochemical batteries produce dc current, a BESS typically consists of the following components:

How big is battery energy storage in North America?

Over the last few years, battery energy storage has grown significantly across North America. In 2014, utility-scale battery storage capacity in North America was approximately 214 MWs. By 2019, this amount increased to 899 MWs. This growth is expected to continue with utility scale storage levels reaching 3,500 MWs by 2023.

Should battery storage standards be updated?

The Institute of Electrical and Electronics Engineers (IEEE) should update the IEEE Standards to reflect any implications of battery storage systems. The GADS Working Group should ensure that battery storage is accurately reflected in their data capturing protocols.

Are flow batteries the future of battery storage?

Lithium-ion batteries account for more than 50% of the installed power and energy capacity of large-scale electrochemical batteries. Flow batteries are an emerging storage technology; however, it still constitutes only 2% of the market. Advances in technology, decreasing costs, and changes to FERC and other market rules will promote BESS growth.

Can battery storage improve grid frequency stability?

The study results demonstrate that battery storage can provide sufficient frequency response to support grid frequency stability and improve frequency performance for large generator tripping events and other frequency disturbances for a future high penetration IBR grid with heavily reduced grid inertia.
