Study on available transfer capability of multi-section in power system considering transient stability

This paper firstly summarizes the newest research on Available Transfer Capability (ATC) algorithm in home and abroad. By analysis of the influence of Adjusting Strategy of Generators (ASG) to power flow and transient stability, this paper derives three indexes which reflect the property of transient stability of generator based on the Equal Area Criterion (EAC). In order to improve the reliability of ATC algorithm, an ASG which considering the transient stability is proposed. Meanwhile, a new ATC algorithm of Multi-Section based on the analysis of correlations between two sections is also proposed. This algorithm avoids the increase of equation dimension by using man-machine unit division method, so that the works for further calculation can be reduced greatly. At last, the validity of proposed algorithm is verified by the calculation result of CEPRI 36-bus system.
