摘要：
Aiming at the influence of uncertain time delay characteristics of temperature control load on the voltage stability of microgrid, a robust control method of voltage stability of microgrid based on T-S fuzzy model is proposed. In this paper, based on the modeling research of time-delay characteristics of uncertain temperature control of microgrid, a voltage stabilization TS fuzzy system control model is established, and a microgrid reactive power fuzzy feedback controller is designed to keep the voltage stability by reactive power regulation when without external disturbance. Voltage stability is maintained by reactive power regulation. Based on the voltage-stabilized T-S model, the voltage stability mechanism under external disturbance such as the sudden increase or decrease of other loads in the microgrid or the start-stop of the power plant is considered. A robust control method for microgrid voltage stability H∞ is established. The improved three-machine nine-node microgrid temperature-controlled load uncertain time-delay simulation system model is studied. The proposed voltage stability control method is verified by numerical simulation. The simulation results show that the H-robust control under temperature-control load uncertainty with time delay based on the T-S fuzzy model can effectively improve the voltage stability of the microgrid. © 2021, Solar Energy Periodical Office Co., Ltd.
