Abstract

In order to ensure that the voltage and frequency of the sending system with a high proportion of renewable energy access under transient port energy impact can be controlled within the allowed fluctuation range, a nonlinear multi-objective transient voltage and frequency-coordinated control strategy for the renewable energy sending system is proposed in this paper. First, the dynamic balance characteristics of the renewable energy sending system under transient energy impact are analyzed by establishing an equivalent power source model, and the frequency and voltage state equation of the sending system considering transient energy impact is studied and established. Then, considering the supporting effect of energy storage on the voltage and frequency of the renewable energy sending system, a nonlinear transient frequency and voltage-coordinated control model of the renewable energy sending system is proposed. Finally, the aforementioned conclusions are verified by simulation analysis. The simulation results show that the proposed control method can realize voltage and frequency stability control under transient energy. The effective energy tracking control algorithm can better utilize the fast energy regulation characteristics of battery energy storage, which can effectively reduce the fluctuation amplitude of the transmission system and restore synchronization in a short time. The voltage frequency control algorithm can significantly reduce the amplitude of voltage and frequency fluctuations, and can realize the rapid suppression of voltage and frequency fluctuations.
