Real Time Synchrophasor Measurements Based Voltage Stability Monitoring and Control (S-65)

Summary This proposal attempts to improve the situational awareness of the power grid by assessing the short term and long term voltage stability in real time using Synchrophasor measurements. These methods have been validated on standard IEEE test cases and their performance on a real system (~ 10,000 buses) will be studied. The analysis will provide insights on the effective locations for short term monitoring and efficient control strategies. The long term voltage stability assessment using a reduced local network for a given limited number of phasor measurement units will be developed. These algorithms will be integrated and implemented on a Real Time test bed for validation and to anticipate issues in actual implementation.
