Abstract:

With the continuous development of power grid technology, the application of composite energy storage electronic transformer in source containing power grids is becoming increasingly widespread. However, in practical operation, energy storage power electronic transformers face challenges such as voltage drops or interruptions in the power grid, which puts higher demands on their stability and power quality. This article reviews the coordinated control and monitoring strategies of transformers based on voiceprint recognition. Firstly, the principle, structure, and current technical characteristics of composite energy storage electronic transformers are analyzed; Based on this, the application of voiceprint recognition technology in energy storage electronic transformers was further explored, and finally, the coordinated control and monitoring strategies of transformers under voiceprint recognition technology were summarized. I hope to provide some theoretical reference for future research.

Key words: including source power grid, composite energy storage power electronic transformer, voiceprint recognition, coordinated control
