Rising levels of inverter-based resources and the accompanying retirement of the synchronous machine fleet is changing the dynamics of how the system achieves/ensures stability. However, the shift is not toward a network made up solely of inverter-based resources. Synchronous machines will remain present into the future and include the synchronous generators of today (at least…

ESIG recently released a report titled Redefining Resource Adequacy for Modern Power Systems, which laid a foundation for new ways to think about resource adequacy and reliability as the grid decarbonizes. In that work, we laid out six principles to guide changes to the way we consider and quantify resource adequacy in an era of…

In order to combat climate change, there is a global need for deep decarbonization, and all sectors that produce carbon dioxide (CO2) must play a role. In 2019, global CO2 emissions from fossil fuels totaled ~33 gigatons, with ~41 percent coming from the power generation sector. The good news is that there are solutions available…

A case study in South Australia Under Frequency Load Shedding (UFLS) is the last resort “safety net” that protects consumers from a black system event when severe disturbances occur. It involves the automatic disconnection of large quantities of load in millisecond timeframes to rapidly rebalance the power system and arrest frequency decline following a severe…
