The large-scale and high proportion of wind power, photovoltaic and other new energy with power electronic equipment as the core interface are connected to the power grid, and the wide application of flexible DC transmission and energy storage system has profoundly reshaped the transient electromagnetic characteristics of the power system. With the increase of switching frequency, power density and the complexity of system topology, the problem of broadband electromagnetic interference has become increasingly prominent, which not only threatens the reliable operation of secondary equipment such as measurement, protection and control, but also may induce or aggravate system level faults. At the same time, the fault tolerance of power electronic system is significantly different from that of traditional system. Its complex fault current characteristics, limited current limiting ability and fast fault propagation speed have brought unprecedented challenges to the rapid and accurate detection, safe removal and system recovery of faults. The deterioration of power system electromagnetic environment and the reconstruction of fault recovery ability have become the key bottleneck restricting the safe, reliable and efficient operation of new power system. This topic focuses on breaking through the ability of interference calculation and protection, accurate state perception and rapid fault recovery in the complex electromagnetic environment of the new power system. The core topics include, but are not limited to:
1 Calculation and test technology of electromagnetic interference in new type power systems
2 Reliability of sensing equipment in new type power systems
3 Fault early warning and condition monitoring technology of new type power systems
4 Fault clearing of new type power systems
