A Novel Approach for ATC Computation in Deregulated Environment

This paper presents a novel method for determination of Available Transfer Capability (ATC) based on fuzzy logic. Adaptive Neuro-Fuzzy Inference System (ANFIS) is used to determine the step length of Homotophy continuation power flow method by considering the values of load bus voltage and change in load bus voltage. The approach is compared with the already available method. The proposed method determines ATC for various transactions by considering thermal limit, voltage limit and static voltage stability limit and tested in WSCC 9 bus system, New England 39 bus system and Indian 181 bus system
