As an important method of computing Available Transfer Capability in transmission network, the continuation power flow is always favored by electric operators. Based on the ATC model of P-Q decomposition, the method of predictor-corrector during computation of ATC is presented. In the iterative, the constant matrixB'and B" take the place of variable Jacobian matrix. It can reduce the requirements of storage capacity. The computation speed can be improved. The proposed method is applied to the IEEE14 bus system. Compared to the method based on Newton-Raphson, the result proves that the proposed method is valid.
