What is Frequency Regulation Using Energy Storage?
Frequency regulation using energy storage employs battery, flywheel, and other storage systems to maintain grid frequency stability through primary, secondary, and tertiary control in power systems with high renewable penetration.
This subtopic focuses on control strategies for energy storage systems (ESS) to provide inertia and damping against frequency deviations caused by intermittent renewables. Key approaches include virtual synchronous generators (VSG) and active power control in microgrids. Over 10 papers from 2005-2024, with Guerrero et al. (2012) cited 939 times, review ESS roles in power quality and frequency support.
Why It Matters
ESS enables grid stability in renewable-heavy systems by recycling energy for rapid frequency correction, as shown in flywheel regulation by Lazarewicz and Alex (2005). In microgrids, coordinated ESS control maximizes PV utilization while preventing overcharge, per Wu et al. (2014). VSG-based ESS mimics synchronous generator inertia, addressing low-inertia challenges from inverter-based resources (Chen et al., 2020; Li et al., 2019). Applications include islanded microgrids and large PV farms, improving capacity factors (Rallabandi et al., 2018).
Key Research Challenges
Low System Inertia
Inverter-dominated grids lack rotational inertia, causing rapid frequency nadir drops during disturbances. VSG control emulates inertia but requires adaptive tuning for variable renewables. Chen et al. (2020) model VSG implementation to assess stability.
ESS Overcharge Prevention
Coordinated active power control is needed to balance PV generation, loads, and ESS state-of-charge in islanded microgrids. Fixed droop controls fail under fluctuating conditions. Wu et al. (2014) propose autonomous regulation strategies.
Seamless Mode Transitions
Microgrids must synchronize frequency and phase for islanded-to-grid reconnection under harmonics and unbalance. Distributed synchronization strategies mitigate distortions. Tang et al. (2015) develop active synchronization for seamless transfer.
