Abstract
The output power of high-penetration wind power and photovoltaic generation in microgrid is random and fluctuating. Meanwhile
the load power in microgrid is stochastic and varying
which easily causes frequency fluctuations in the microgrid. Moreover
the operation mode change of the microgrid will cause in variations in both network equivalent parameters and operation parameters. Consequently
aiming at frequency fluctuations and parameter perturbation of controlled objects in AC/DC hybrid microgrid
this paper proposes a frequency control method for the AC/DC hybrid microgrid based on
H
∞
mixed sensitivity
which can control and stabilize the AC-region frequency. Firstly

function is constructed by converting a practical problem into a mixed sensitivity problem. Secondly
a frequency-robust controller is designed
which enhances the robustness of the frequency at parameter perturbation. Besides
the Riccati equation is introduced to describe the robust control problem. This equation is solved by linear matrix inequality method to obtain the
H

frequency controller. Finally
the correctness and feasibility of the designed frequency control method are verified by MATLAB/Simulink simulation platform.
