Analysis and Assessment of Frequency Regulation Capability of Coal-Fired Power Generating Units under Deep Peak Shaving

Primary frequency regulation capability assessment has attracted considerable attention with the integration of large-scale renewable energy into power system. In this work, the main interfering factor is considered in the PFC capability assessment under deep peak shaving condition of the coal-fired power generating units. Some assumptions are made and a novel prediction model is proposed under 30-100% rated load of power units. Results show that the proposed model with high accuracy can be used to evaluate the actual PFC capability.
