Energy Storage and Frequency Regulation Construction Plan

What role does frequency regulation play in energy storage commercialization?

Recently, other regions such as California have seen substantial energy storage deployment. Frequency regulation has playeda large role in energy storage commercialization, and will continue to play a role. But how large a role depends on changes to the design of PJM’s frequency regulation market.

Can centralized power plants provide frequency regulation services?

Traditionally, centralized power plants (like hydropower, steam generators, or combustion turbines) have provided frequency regulation services. Following recent technological and cost improvements, energy storage technologies (including batteries and flywheels) have begun to provide frequency regulation to grid systems as well.

What role does frequency regulation play in grid balancing?

Along with other timescales of grid balancing, frequency regulation has an important role in themodernization of grid flexibility in the transition towards larger shares of intermittent renewables. Energy storage will play an increasingly important role to make power grids more reliable and help keep the lights on.

Should frequency regulation be streamlined?

In this sense, streamlining the frequency regulation market design—even if it negatively affects energy storage providers today—helps make the electricity system more efficient and able to incorporate more renewable energy resources in the future.

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.

How can battery energy storage systems improve frequency response?

However, with more solar and wind power integrated into the grid, the system’s ability to stabilize frequency declines. To address this challenge, Battery Energy Storage Systems (BESS) are now playing a critical role in delivering fast, precise frequency response services.
