构建新型电力系统电压治理体系:挑战、实践与展望OA

During the development of modern power systems,the"dual-high"characteristics—high penetration of renewable energy and high power-electronic interfacing—have become increasingly prominent in power grids.Conse-quently,voltage issues have evolved from localized,technical challenges into systemic and multi-level risks to safety and stability.In this context,and in light of the structural transformation and operational characteristics of the modern power systems under the"dual-carbon"goals,this paper systematically analyzes the causes and manifesta-tions of bidirectional voltage violations,pronounced power quality problems,reduced voltage stability margins,and rapid reactive power fluctuations.The paper further examines the multiple challenges currently faced in voltage gov-ernance,including unclear voltage regulation mechanisms,insufficient reactive power regulation resources,and a lack of coordinated control mechanisms.Finally,key technologies and practical experiences for building a voltage governance framework are presented,aiming to provide theoretical insights and practical pathways for the develop-ment of secure,high-quality modern power systems.
