Available Transfer Capability Evaluation for AC/DC Hybrid System
摘要
Abstract
Along with the unceasing expansion of the scale of AC/DC hybrid power system in China, the computing model and methodology of available transfer capability (ATC) for AC/DC hybrid power system become the crux to be researched in this field. Power system is a time-varying system with uncertainties and randomness, so it is a difficult point for the accurate calculation of ATC to consider the influence of these factors on it. A non-sequential Monte Carlo simulation-based evaluation method for ATC, in which the uncertain factors such as load fluctuation, equipment failures, variation of control mode for DC system and weather are taken into account comprehensively, is proposed and in the viewpoint of adequacy a series of probability indices are defined for the evaluation of ATC. Relevant calculation program is programmed by Matlab7.1 software, and the case study on improved IEEE 14-bus system is performed. Calculation results show that the proposed method is correct and effective, and more accurate ATC information can be obtained by the proposed method.关键词
