Small-Signal Model and Stability of Electric Springs in Power Grids
IEEE Transactions on Smart Grid, 2018 When multiple stable systems are combined into one system, the newly formed hybrid system has a certain possibility to be unstable. Such a natural phenomenon has been verified in the fields of chemistry and biology over the last century. The implementation of electric springs (ESs) in large quantity over the power grids can also suffer from the same ...

Small-Signal Stability of Power Systems With Voltage Droop
IEEE Transactions on Power SystemsThe stability of inverter-dominated power grids remains an active area of research. This paper presents novel sufficient conditions for ensuring small-signal stability in lossless and constant $R/X$ grids with highly heterogeneous mixes of grid-forming inverters that implement an adapted $V$-$q$ droop control.
