System voltage stabilization control method of a microgrid Robust Control

The present invention discloses a system voltage stabilization control method for robust control based on a microgrid, the smart microgrid system control architecture by the system control layer, a control layer and a centralized local control layer, by coordinating multi-level control, microgrid optimization of the energy of the system voltage and frequency stability control. The present invention establishes a dynamic load in parallel with the integrated load model static load induction motor, the system performance and robust stability constraint condition is satisfied, the mixed sensitivity problem solved using the method of designing a robust controller micro grid voltage stability, to improve micro grid voltage stability. The present invention can accommodate a wide range of variation of the load parameter due to changes in operating conditions, load and frequent switching of the influence of the external environment and other factors make the model parameters generated perturbation microgrid and topology unmodeled portion uncertainty It has a robust and can better suppress noise and parameter drift, while the controller is simple in structure and easy to realize.
