Primary Frequency Regulation Reserve Procurement of Renewable Energy Power System Considering Multiple Damping States and Governor Limiters
摘要
Abstract
Primary frequency regulation is an essential means for the power system to suppress frequency change after disturbance,and this paper researches the primary frequency regulation reserve settling of the renewable energy power system.First,the rising penetration rate of renewable energy power supply on the damping ratio of the system frequency response model is analyzed,and a system frequency response model applicable to multiple damping states is established.Then,considering the fast dynamic response of renewable energy power frequency regulation and the difference in synchronous power governor limiter value,the system frequency response improvement model is proposed,considering the multi-machine governor limiters.Then,the constructed system frequency response improvement model is equivalently transformed into the time domain.The time-domain analytical relationship between the primary frequency regulation reserve and the post-disturbance frequency nadir of various power supplies is established,and its linearization characterization method is further proposed.Finally,for the frequency stability requirement after disturbance,the primary frequency regulation reserve constraint is added to the new energy power system's economic dispatch,and the renewable energy power system's primary frequency regulation reserve settling model is established.Simulation results of the IEEE 39-bus system show the correctness and effectiveness of the proposed model in this paper.关键词
