文摘
A two-level coordinated strategy for large-scale PV farms to regulate grid frequency. New automatic-tuning fuzzy logic controller with changeable output scaling factor. An algorithm is used to manage state-of-charge of battery bank in safe value range. A special control mode to stabilize rapidly grid frequency under emergency cases. Efficacy against changes of weather and AC load, and in multi-area power system.
