Introduction The process for connecting large generators to the bulk electric system in the United States (U.S.) was designed in the early 2000’s. For about a decade, wind and natural gas resources had the largest share in the interconnection queues … [Read more...]

The November 2018 ESIG blog on “Implementation of Inertia Monitoring in ERCOT – What’s It All About?” discussed the importance of synchronous inertia for a power system.  It included the impacts of inverter-based resources on system inertia, and an … [Read more...]

Synchronous inertia characterizes the ability of a power system to oppose changes in electric frequency after large and sudden changes in active power production or consumption. The level of inertia present in a system at any time is dependent on the … [Read more...]
