To secure power system operations,practical dis-patches in industries place a steady power transfer limit on crit-ical inter-corridors,rather than high-dimensional and strong nonlinear stability constraints.However,computational com-plexities lead to over-conservative pre-settings of transfer limit,which further induce undesirable and non-technical congestion of power transfer.To conquer this barrier,a scenario-classifica-tion hybrid-based banding method is proposed.A cluster tech-nique is adopted to separate similarities from historical and gen-erated operating condition dataset.With a practical rule,trans-fer limits are approximated for each operating cluster.Then,to-ward an interpretable online transfer limit decision,cost-sensi-tive learning is applied to identify cluster affiliation to assign a transfer limit for a given operation.In this stage,critical vari-ables that affect the transfer limit are also picked out via mean impact value.This enables us to construct low-complexity and dispatcher-friendly rules for fast determination of transfer lim-it.The numerical case studies on the IEEE 39-bus system and a real-world regional power system in China illustrate the effec-tiveness and conservativeness of the proposed method.
