A review of terminal voltage violation mitigation for distribution networks with high penetration photovoltaic integration
摘要
Abstract
In the context of the steady advancement of the"dual carbon"goals and the construction of the new power system,distributed photovoltaic(PV)generation and other renewable energy sources are being integrated at high penetration levels and on a wide scale.Coupled with the rapid development of emerging electricity consumption forms such as electric vehicles,energy storage systems and flexible loads,distribution networks are evolving from the conventional unidirectional passive structure to a multi-source interactive,active bidirectional system.In this process,the stochastic and volatile PV output,the spatio-temporal mismatch between generation and load,and the reverse power flow and other factors have significantly altered the feeder voltage distribution patterns,and the terminal voltage rise and voltage violation issues have become increasingly prominent under high PV penetration,constituting a critical bottleneck restricting the high-quality accommodation of distributed energy resources and the safe,stable operation of distribution networks.Firstly,this paper systematically analyzes the formation mechanisms and influencing factors of voltage violation,and summarizes the technical characteristics and applicable boundaries of single mitigation approaches including conventional voltage regulation devices and emerging power electronic equipment.Secondly,from the perspective of source-network-load-storage coordination,it concludes core ideas of optimal device configuration and multi-timescale coordinated voltage control,and refines the overall technical framework for coordinated mitigation.Finally,it further analyzes the practical constraints and institutional challenges encountered in engineering implementation,and prospects future research directions such as digitally empowerment,multi-stakeholder collaborative participation,lifetime-oriented dispatch strategies,and coordinated control of AC/DC hybrid distribution networks.关键词
