摘要

In practical power markets, available transfer capability (ATC) can provide important information for all parts of power market participants and the assessment of ATC should be carried out instantly. As high voltage direct current (HVDC) systems have been extensively used in modern power systems, less work has been done on evaluation of ATC in AC-DC hybrid power systems. This paper is dealing with the evaluation of ATC for the integration of HVDC link with an AC power system. The mathematical model of ATC for AC-DC hybrid power system is formulated. Considering the time-varying and uncertainties of the power system, several statistical indices are presented to evaluate ATC. A novel approach combined Monte Carlo simulation with bootstrap method is proposed to calculate these statistics. Sequential solution method is employed to deal with the AC-DC power flow and golden section search method is used to accelerate convergence of load flow. The algorithm is developed in the environment of MATLAB R2008a with MATPOWER. Case studies with a modified IEEE RTS-79 24-bus AC-DC hybrid power system and IEEE 3-area RTS-96 system are used to demonstrate the presented approach. The results show that the proposed method is effective and practical. Some new problems are suggested at the end of paper.
