Due to recent changes in generation patterns with the increase of renewable energy resources and the retirement of some of the conventional generators, the AC transmission grid is becoming increasingly congested. TGS performs studies related to the addition of new AC transmission lines and the addition of new conventional generation. Oftentimes, however, it is difficult to obtain permits for new overhead lines, therefore the use of FACTS devices, such as SVC, STATCOM or TCSC, provides alternative methods to increase and “stretch” the ability of the HVAC grid to handle more power transfer.
TGS has the experience and knowledge to address any HVAC study requirements, including steady state, short circuit, transient stability, SSR and EMT. We also develop custom models for transient stability and EMT programs, such as SVCs or STATCOMs.
