Abstract

In renewable energy integration filed, the grid voltage synchronization signal should be fed back to the gird-tied converter for reliable operation. The frequency and phase information of the grid voltage, and the positive and negative sequence are also needed for the converter control. A sliding-mode grid voltage observer is proposed and verified in this paper under an unbalanced network. The fundamental positive sequence component and fundamental negative sequence component are inherently separated in the observer without employing any additional separated filters. Due to embedded filtering effect, high frequency chattering and harmonic ripples can be well suppressed. The proposed observer is simulated in the environment of MATLAB and simulation results show that the proposed observer is correct and effective.
