[article]
2015
arXiv
pre-print
This paper focused on demonstration of multistability phenomenon in radial distribution systems with reversed power flow, where multiple stable equilibria co-exist at the given set of parameters. ...
High levels of penetration of distributed generation and aggressive reactive power compensation may result in the reversal of power flows in future distribution grids. ...
We dedicate section V to revisit the current emergency control actions and design the pulse emergency control for multistability. ...
