摘要
This paper presents the steady state modeling of static var compensator (SVC) and thyristor controlled series capacitor (TCSC) with their control and limits. Handling of limits and control mode switching are presented and discussed. Bifurcation analysis is applied in order to find the optimal location and rating of these devices and a continuation power flow is used to evaluate the effects of these devices on system loadability. Eigenvector analysis applied at the maximum loading point is used to rank the most critical voltage buses. After that, it would be possible to optimize location, sizing and control modes of SVC and TCSC in order to achieve maximum enhancement of system loadability. The models and methodology for placing and designing SVC and TCSC are tested in a 173 bus AC/DC system. Performance factors are defined to evaluate the efficiency of SVC and TCSC on different conditions. (C) 2003 Elsevier Ltd. All rights reserved.
