Evaluation of Performance Metrics for Electric Grid Operational Scenarios

Abstract

Today's power grid infrastructure is evolving faster than ever, as is its complexity. To effectively address the challenges of grid modernization, upcoming power engineers need more first-hand, practical experience operating these power systems. Several interactive operational scenarios have been developed in order to allow the users to get hands-on experience with a simulated power grid. This paper develops several metrics to evaluate the trainees' performance during an operational scenario. Operating reserve should be quickly available to maintain system reliability. Voltage schedules also play an important role in keeping equipment within system operating limits. Transmission line loading constraints prevent the system from exceeding thermal and stability limits after credible contingency events. In this work, these three metrics are monitored throughout the interactive simulation and used to guage user performance. To give general insight on how well a trainee performs, an overall Performance Score (PS) combing these three metrics is calculated at the end of assessment.
