Review of Broadband Impedance Measurement Techniques and Equipment for Renewable Energy Generation
With the large-scale integration of global renewable energy generation
broadband oscillation risks in power systems at home and abroad have become increasingly prominent
posing significant threats to the stable and safe operation of the power systems. Impedance-based stability analysis has emerged as an effective methodology for analyzing and mitigating oscillation issues. Accurate acquisition of broadband impedance characteristics serves as the fundamental prerequisite for oscillation analysis
where specialized impedance measurement equipment plays a pivotal role. This paper first conducts a comprehensive review of the historical development of impedance measurement equipment worldwide. Subsequently
measurement principles
topological configurations
practical applications
and performance metrics are systematically analyzed. Finally
the paper provides a comprehensive summary
along with recommendations for technological advances
engineering application
and standard formulation of impedance measurement equipment in the future.
