Sažetak
This paper investigates the impact of the UPFC on alleviation of voltage stability problem from dynamic and static aspects. The control system of the UPFC’s injection model is developed and the benefits of its contribution to avoiding of voltage collapse are explored by analysing a multi-machine test system. During dynamic time-domain simulations, the extended Jacobian matrix and state matrix are evaluated utilising linearised differential equations of generators and recovery loads as well as steady-state load flow equations. From a static approach, according to eigen and singular value decompositions of the matrices, the participation factors are computed resulting with the most critical locations in the system where the UPFC could be installed with significant impact in the voltage emergency situations. Sensitivity analysis of the matrices enables the knee-point in well known PV curve to be recognised denoting one of the possible moments for voltage support from the UPFC.
