基于演变视角的新型电力系统解列控制研究综述OA

To address the challenges posed by the increasingly complex transient characteristics of modem power systems and the insufficient conservatism of traditional controlled islanding,this paper provides a comprehensive review of is-landing 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.
