The structure of the electric power system has been shifting with the penetration of renewable resources and large loads like crypto mining facilities and hydrogen production facilities. Due to this changing dynamic, the electric power system is prone to more stability issues, causing load modeling to become even more important.

In a paper published at the 2023 IEEE Power & Energy Society General Meeting (PESGM), engineers at EPE evaluated the need for detailed load modeling by utilizing both frequency domain analysis and transient simulation studies. The need for accurate load modeling was substantiated by transient studies on a 2,500 MW islanded system consisting of renewable generators and a hydrogen production facility.

The study also emphasized the importance of load modeling in controller tuning using small signal analysis. An automated procedure for tuning the response for multiple grid-forming inverters (GFM) was presented as well.
