System operators around the world face the increasing integration of distributed energy resources (DERs) into the power grid. DERs – small-scale, decentralized generators such as rooftop solar panels, wind turbines, batteries, and electric vehicles – are connected to the distribution system, whereas larger inverter-based resources are often connected to the transmission system and can be…

As the power system continues to evolve with an increase in inverter-based resources (IBRs), there could be a need to adopt future inverter technology and capability that could allow for operating a 100% IBR network in a safe, secure, and reliable manner. Such inverter technology has been labeled as grid-forming (GFM) in certain industrial discussions.…

EirGrid and the System Operator for Northern Ireland (SONI) are the transmission system operators (TSOs) for Ireland and Northern Ireland, respectively. Together the Ireland and Northern Ireland power systems constitute a synchronous system with a peak demand of approximately 7 GW. In 2022, approximately 40% of electricity used on the island of Ireland came from…

  In recent decades, the electric power utilities have integrated a sizeable amount of renewable energy source (RES) technologies into the power system. Their generation is inherently variable and not easy to precisely forecast in the medium term. Nonetheless, at small penetrations, the power system can still be operated more or less in a traditional…

  With the growing role of wind energy in our power systems, the challenge of maintaining grid stability becomes increasingly critical. The key to this challenge is advanced and accurate modeling. Models are essential for ensuring the reliability and efficiency of our electric grid as we shift toward more renewable energy sources. Evolution of Wind…
