- Abstract
- In today's electric power industry, accurate and flexible information is needed to provide nondiscriminatory access to all market participants. This paper primarily purports to determine available transfer capability (ATC) based on the fuzzy set theory for continuation power flow (CPF), thereby capturing uncertainty. Assuming that uncertainties involved in the ATC calculation are estimated or measured, a fuzzy model is formulated in which major uncertainty parameters affecting the ATC are regarded as fuzzy variables subject to their possibility distributions. The purpose of this paper is to elaborate main features of the fuzzy continuation power flow (FCPF) algorithm that can handle uncertainties in load parameters and bus injections as well. As such, the robust solution will assist in providing additional information on the actual ability of the network to a system operator. In other respects, it poses a significant influence on the potential curtailment of power trades from which the reinforcement strategy can be set by the system operator. The viability of the proposed method would be verified through a stark contrast with the ones obtained from the conventional CPF and the fuzzy power flow (FPF) in the IEEE-24 RTS bus system and in the IEEE-118 bus system.
