Adaptive phasor power oscillation damping controllers (APPODs) produce superior large signal performance with very little reliance on accurate system models. However, recursive phasor estimation, online frequency correction and adaptive phase-shift are involved which makes modeling such APPODs difficult in stability studies. Possible interaction with other controllers (e.g. lead-lag compensators)...
An adaptive critic design (ACD)-based damping controller is developed for a thyristor-controlled series capacitor (TCSC) installed in a power system with multiple poorly damped interarea modes. The performance of this ACD computational intelligence-based method is compared with two classical techniques, which are observer-based state-feedback (SF) control and linear matrix inequality LMI-Hinfin robust...
This work is a step towards real-time implementation of a single-input single-output (SISO) adaptive controller scheme for power oscillations damping (POD) making use of fast power electronic devices such as FACTS (flexible AC transmission systems). The adaptive control is based on a recursive parameter estimation using Kalman filtering techniques and a pole shifting method which takes into consideration...
In this paper, a nonlinear feedback excitation control is presented for power systems with uncertainties. In order to achieve the transient stability enhancement, the control law can be designed based on the adaptive backstepping method by a recursive way without linearization. Lyapunov function method is applied to analysis the convergence of the power angle and relative speed of the generator and...
