Abstract
With the transformation of energy structure and the rapid growth of power demand, smart grid, as an important development direction of modern power system, its power quality problem is increasingly paid attention to. This study aims to improve the power quality of smart grid, and deeply discusses the application potential and realization path of power electronics technology in this field. Firstly, the causes of the typical power quality problems in the smart grid and their effects on the stability of the power system and the user experience are analyzed, and then the technical requirements for dynamic compensation and optimization control through power electronic devices are clarified. Based on this, this paper proposes a design method of power electronic controller based on advanced topological structure, combined with real-time monitoring and intelligent algorithm to realize the efficient control of key indicators such as voltage fluctuation, harmonic distortion and power factor. Through simulation modeling and experimental verification, the results show that the proposed scheme can significantly reduce the harmonic content in the power grid, and effectively inhibit the voltage temporary drop and short-time interruption phenomenon, so as to greatly improve the power qualit.
