Building the new power system with renewable energy as the main body is a key measure of the energy and power industry to promote the realization of the goal of “carbon emission peaking and carbon neutrality”. With the large-scale integration of multiple types of power electronic equipment into the system
the efficient collaboration of source-grid-load-storage has made the harmonic pollution intensify and become more complex and variable
presenting a globalized characteristic
which affects the high quality and reliable power supply of the power system. This paper focuses on the harmonic source tracing under the interaction of multiple types of harmonic sources
and deeply integrates the advantages of advanced digital technology in data resources and intelligent collaboration to carry out dominant source identification and harmonic contribution evaluation. First
around the concept of harmonic source tracing
the new challenges and opportunities faced by the new power system on the background of digitalization are analyzed. Then
the current status of harmonic source tracing research is elaborated
and the new development requirements of key technologies are pointed out. On this basis
a cloud-edge-end collaboration strategy of harmonic source tracing is designed by using the technical architecture of digital power grid. Under the background of digitalization
the main technologies of harmonic source tracing in data collecting
mechanism analysis
and collaborative application are described. Finally
this paper prospects the technology direction for the secure
reliable
and flexible development of digital power system in the future.
