Does frequency regulation play a role in energy storage commercialization?

Frequency regulation has played a 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. PJM embarked on these changes in an effort to correct observed problems in the market.

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.

Does energy storage need a regulatory framework?

For energy storage to fully realize its potential, a robust regulatory framework is needed. In the European Union (EU), the role of energy storage in EU power markets will be formally recognized in the Electricity Market Design Directive (recast), which is expected to be adopted in Q1/Q2 2019.

What is a battery energy storage system?

FFR, FCR-D, FCR-N, and M-FFR form the backbone of modern frequency regulation strategies. Each service plays a unique role in stabilizing power systems, from milliseconds to minutes after a disturbance. Battery Energy Storage Systems, with their speed, accuracy, and flexibility, are uniquely positioned to deliver all these services effectively.

Which power system is best for delivering FFR?

Thanks to their millisecond-level response times and inverter-based architecture, BESS are ideal for delivering FFR. This makes them especially valuable in power systems with low inertia and high renewable penetration, where traditional mechanical generators are too slow to react. 2. FCR-D (Frequency Containment Reserve – Disturbance)
