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 … [Read more...]
Harmony in Synchrony with Inverters and Synchronous Machines
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 … [Read more...]
Impact of Large Shares of DER on the Bulk Power System (BPS)
The increasing percentage of distributed energy resources (DERs) brings a degree of uncertainty in bulk power system planning and operations. Additionally, it introduces an element of uncertainty with regard to distribution planning and operations, … [Read more...]
On the Road to Grid-Forming Inverters: When and How Many Will We Need?
AC/DC is not only a rock band of repute with countless classics under their belt, but it was also the topic of the great current war between Tesla and Edison. Both approaches, however, required the presence of a rotating machine, inside which the … [Read more...]
Control and Communication in an All Inverter Power System
At night, in a large open field, one can chance upon hundreds of individual blips of light from fireflies. As time progresses, it has been observed that these blips of light start synchronizing with each other, first in small clusters, then as larger … [Read more...]
Ignoring Electrical Frequency in an All Converter Power System
Since the early 1900s, with the proliferation of alternating current rotating generators and development and setup of electric grids, the electrical frequency in the network has nobly served as the pulse of the electric power system. The electrical … [Read more...]
