Roles of Dynamic State Estimation in Power System Modeling, Monitoring and Operation

Power system dynamic state estimation (DSE) remains an active research area. This is driven by the absence of accurate models, increasing availability fast-sampled, time-synchronized measurements, and advances in capability, scalability, affordability computing communications. paper discusses advantages DSE as compared to static estimation, implementation differences between two, including measurement configuration, modeling framework support software features. The important roles are discussed from modeling, monitoring operation aspects for today's synchronous machine dominated systems future power electronics-interfaced generation systems. Several examples presented demonstrate benefits on enhancing operational robustness resilience 21st century through time critical applications. Future directions identified discussed, paving way developing next energy management
