Transient stability prediction and control in real-time by QUEP
A method for the real-time analysis and control of power system transient stability has been developed incorporating detailed machine models. The method uses a quasi-unstable equilibrium models. The method uses a quasi-unstable equilibrium point (QUEP) energy function approach to evaluate the stability margin of a power system. The mode of disturbance which best predicts stability is determined very rapidly by a new generating unit clustering procedure. Transient stability sensitivity coefficients are calculated for use in a constrained economic dispatch algorithm. Corrective action constraints are developed as simple limits on the sums of generator outputs. A theorem stating the necessary and sufficient conditions for the existence of a power system energy function is also presented.
