A Novel Approach for Security Analysis using Shift Factors for Limited Synchrophasor Observability

The adoption of synchrophasor technology has increased rapidly in the past decade. Many system operators have made applications available to operators, reveal hidden operating conditions, and increase grid resiliency. development Linear State Estimation provided an innovative method solve states linearly at a faster rate, serve as backup EMS should conventional Estimator fail solve. Advanced were developed take advantage LSE solution provide with alternative contingency analysis using synchrophasors data [6]. However, currently explored are presumed run iteratively every couple minutes, therefore not taking high resolution measurements synchrophasors. This work proposes monitor limits by leveraging linearization methods for analysis, better utilize benefits Also, practical approach is proposed handle lack full observability, ensure tool operability industry infrastructure.
