A New Method for Constructing the Static-Voltage-Stability Boundary with a Conversion Strategy
Source abstract
Abstract
The static-voltage-stability region (SVSR) is an effective tool for monitoring the safe operation of grid voltage. Rapidly obtaining the static-voltage-stability-region boundary (SVSRB) of a power system is crucial for the application of SVSR technology. First, this paper reveals the mechanisms underlying the failure scenarios that may occur with conventional boundary tracking methods. Then, an improved method incorporating curve extrapolation and correction conversion strategies is proposed, which enhances the efficiency of constructing the SVSRB. Furthermore, the analytical expression of the SVSRB is derived from the intermediate information obtained during the predictor stage. Finally, simulation examples based on a simple power system, the IEEE 3-machine, 9-bus power system and IEEE 300-bus power system were developed to verify the accuracy and efficiency of the proposed method.
