| 中文摘要 | A grid-forming inverter (GFI) is an important component for operation of an islanded microgrid. Its purpose, similar to a conventional slack bus generator, is to build up a reference voltage for other distributed generating units in the microgrid. Usually, a nested-loop PI control structure is employed to control a grid-forming inverter in a dq reference frame. However, conventional PIbased nested-loop control method has a deteriorative performance under parameter variations. In this paper, a novel nested-loop control strategy is proposed for control of a grid-forming inverter system containing an LC output filter and loads. The proposed method doesn’t require a precise model for the inverter system and can better deal with uncertainties and LC filter resonance without using any passive or active damping mechanisms. It utilizes a sliding mode control in the inner current loop and a mixed H2/H1 optimal control in the outer voltage loop, which provides the advantages of constant switching frequency, low total harmonic distortion (THD), robustness against parameters variations and fast transient response. The simulation and hardware experiments presented in this paper demonstrate the proposed controller’s improved transient and steadystate performance in various key criteria, over conventional PI-based nested-loop control strategy. |
