Stability Control for Grid-Connected Inverters Based on Hybrid-Mode of Grid-Following and Grid-Forming

IEEE transactions on industrial electronics (1982. Print)
Grid-connected inverters (GCIs) operating in grid-following (GFL) mode may be unstable under weak grids with low short-circuit ratio (SCR). Improved GFL controls enhance the small-signal stability of GCIs under weak grids but result in a decrease in ...

Grid Forming Metal Coordinating Macroligands: Synthesis and Complexation

2006
The synthesis of poly(L-lactide) bispyridylpyridazine macroligands from a hydroxyl functionalized ligand by controlled ring-opening polymerization is described. The resulting macroligands were characterized by 1H-NMR spectroscopy, GPC and MALDI-TOF MS. The metal coordination of those macroligands with copper(I) resulting in polymeric [2x2] metal grids ...
