A Comparison Between Inverters with Grid Forming vs. Grid Following Technology

GERS USA | Monday, June 12, 2023

Currently, most  non-conventional  renewable plants use grid-following (GFL) inverter control strategies.  These technologies have allowed for the increase of IBRs in the  network, but have reduced the robustness of the system in terms of voltage and frequency. In order to perform a quick review of existing technologies in generation and their impact on system performance, the table is shown below. 

GERS has carried out interconnection studies of projects totaling more than 13.6 GW of synchronous and inverter-based generation. Within the framework of these studies, Load Flow analysis, short circuit, RMS and EMT stability and protection coordination studies have been carried out to comply with TPL-004-1, PRC-024-3, IEEE 2800-2022 regulations, among others, through the use of  simulation software with reliable software such as NEPLAN, EMTP-RV or PSS®E.
