The problem of regulating voltages within the required limits is complicated by the fact that power system supplies power to a vast number of loads and is fed from many generating units. As loads vary, reactive power requirements of the transmission system vary. Moreover, voltage magnitude is relatively less sensitive to active power compared to reactive power due to high X/R ratio of transmission...
This paper presents a methodology for the identification of critical locations of power systems using eigenvalue analysis of measurements of the system variables. The eigenvalue analysis is implemented using Principal Component Analysis (PCA) and the methodology is tested on the IEEE 118- bus system. The identification of critical locations in a power system would enable the utility company smartly...
This paper has two main objectives: to explain the dynamic characterization of wind farms as part of their integration in power systems using modal analysis and to present a qualitative development for understanding the main factors that impact on the damping of the oscillation modes by incorporating wind farms based on variable speed wind turbines. Moreover, such developments are validated by performing...
