To address the challenges posed by the increasingly complex transient characteristics of modern power systems and the insufficient conservatism of traditional controlled islanding
this paper provides a comprehensive review of islanding control research from an evolutionary perspective. First
this paper traces the developmental path of islanding control
from passive islanding based on local criteria with limited flexibility to active islanding which can enable online controls
and further moves toward adaptive islanding that establishes a multi-dimensional coordinated defense system. Second
this paper analyzes the coordination issues across the temporal chain
and systematically examines the core tasks and collaborative approaches across five stages
namely
planning
steady-state operation
post-fault pre-out-of-step
post-out-of-step pre-islanding
and isolated grid operation after islanding. Third
this paper summarizes the core factors influencing islanding
and discusses the impacts of three categories
namely
grid-connected component characteristics
network topology
and power system faults. Finally
based on the evolutionary context outlined above
this paper puts forward the prospects in key future research directions in following four areas: reunderstanding instability mechanisms
refining islanding technology
enhancing multi-level control coordination
and utilizing artificial intelligence assistance
aiming to provide a theoretical reference for building an islanding defense system suited to new-type power systems.
