Abstract :
Voltage stability margin of regional network is not a fixed quantity but closely related to operation condition and operation constrains. This paper proposes an effective method to estimate the real-time voltage stability margin based on some locally synchrophasor measurements. A Radial Basis Functions (RBF) neural network is employed to estimate the regional margin. The validity of the method is illustrated by case studies on the IEEE 30-bus system.
