Coordinated Frequency Regulation Strategy for Wind-Storage Systems
摘要
To address operational uncertainties and dynamic fluctuations in contemporary power networks induced by high-penetration wind energy integration, this study introduces a hybrid energy storage architecture (HESA) for coordinated wind farm grid synchronization and frequency stabilization. An optimization framework is developed for HESA-assisted frequency regulation, incorporating three critical operational dimensions: 1) temporal coordination of turbine-storage collaborative response; 2) charge-dynamic modeling of storage systems in frequency modulation; 3) adaptive control strategies based on real-time energy reservoir fluctuations. The frequency stabilization protocol is systematically partitioned into tri-phase operational modes: turbine-dominant regulation, coordinated wind-storage adjustment, and storage-centric compensation, effectively managing intermittent frequency deviations. Validation experiments employing a quadruple-generator dual-zone configuration demonstrate enhanced primary frequency regulation capability through integrated energy storage coordination.
