This paper discusses two types of transient frequency regulation (TFR) scenarios with source-storage collaboration, where wind power and energy storage are used as auxiliary TFR resource. First, a distributed ultra-short-term wind power forecasting (WPF) method is proposed to facilitate the TFR resource planning of system operators.
