Unbalanced distribution network fault analysis with hybrid compensation
IET Generation, Transmission & Distribution, 2011 Fault analysis with hybrid compensation for unbalanced distribution systems is proposed. The method employs the unbalanced three-phase model to analyse faults. Two matrices containing information of the topological characteristics of distribution networks were built along with the proposed hybrid-compensation method for analysis.

IET Power Electronics, 2015 An improved control scheme for delta‐connected cascade multilevel static synchronous compensator (STATCOM) operating under unbalanced conditions is proposed. The individual phase instantaneous current control is suitable for delta‐connected cascade multilevel STATCOM which can be equivalent to three single‐phase inverters.
