Modeling of Load for Transmission Systems Analysis: Aggregate versus detailed and positive sequence vs electromagnetic transient [Feature]

Analysis of multiple historical and recent grid events have highlighted the importance of load modeling in power system studies. Load modeling is however challenging as compared to modeling of other power system equipment. To this, improved energy efficiency, increased electrification, boom in data centers, servers, cryptocurrency sectors and projected growth in green hydrogen production have also increased the complexity. This article delves into the various intricacies involved in modeling load, both in aggregate and in detail, and in positive sequence and EMT domain.
