Microgrid dynamic modeling

The modeling and computational requirements to represent in detail equipment and conditions to properly study stability in Microgrids (MGs) could be very onerous, requiring models and tools that restrict the types of studies that can be performed. On the other hand, model approximations that reduce computational burden might not be sufficient to fully analyze the stability of these systems. Therefore, this panel will focus on discussing the validity and applications of detailed and approximate component models and simulation tools for MG dynamic studies, in particular generator and grid modeling, converter models, unbalanced and balanced system conditions, dynamic and static loads, controls integrated with communication technologies, and protection systems. Phasor vis-à-vis electromagnetic transient simulation tools for dynamic stability analyses will also be discussed, including the application of dynamic phasor and co-simulation approaches for these kinds of studies. Finally, modeling scale-up issues as well as MG equivalent models will be examined.
