Practical Challenges of Integrating Synchrophasor Applications into an EMS

With the exploding growth of synchrophasor PMU
data in utility control centers, there is an increased emphasis on
successful integration of existing model-based Energy
Management Systems (EMS) applications with the new
complementary PMU measurement-based applications. This is
necessary to gain confidence of the newly integrated data, while
embracing these new measurement-based tools and techniques.
These new generation of synchrophasor applications have
moved beyond prototype to the Proof of Concept (PoC) stage.
Once validated and accepted by end users, field installation and
training, the tools will become part of the day-to-day,
production EMS. The synchrophasor applications include
Linear State Estimator (LSE), Oscillation Detection, Voltage
Stability indicators, etc. Enhanced tools to validate results and
advanced simulation tools for training are other areas for
development. The integration tasks pose many challenges and
are addressed in this paper.
