iThis ipaper iproposes ia ihierarchical iFuzzy iInterface iSystem i(FIS) iPredicated icontrol iarchitecture idesigned ifor ian iarbitrary ihigh ivoltage imulti iterminal idc i(MTDC) inetwork. iModular imultilevel iconverter i(MMC)is ia iwell-proved icircuit itopology iin ivoltage-source iconverter-based ihigh ivoltage idirect icurrent i(VSC-HVdc) itransmission isystems. iAs iis iknown, ithe iconventional ihalf-bridge isubmodule i(HBSM)-based iMMC-HVdc iis inot isuitable ifor ioverhead iline itransmission iapplications. iIn iaddition, ihigh ienergy istorage irequirements, ii.e., ilarge icapacitance iis iinevitable. iThe iconventional idesign iof ithe ifull-bridge isubmodule i(FBSM)-based iMMC iusually idoes inot iutilize ithe inegative ivoltage istate iof iFBSM iin inormal ioperation. iConsidering ithe isame idc ivoltage ias iwith ithe iHBSM icase iand iutilizing ithe inegative ivoltage istate iof ithe iFBSM, ithis ipaper ipresents ithe idesign imethod iof ithe ipower itransmission icapability iof ia isingle iFBSM. iMeanwhile, ian ioptimized ienergy istorage icapacitance idesign imethod iof ithe iFBSM iis iproposed. iWith ithis imethod, ithe icapacitance iof iFBSM ican ibe ireduced isignificantly. iThe icorrectness iand ieffectiveness iof ithe iproposed imethod iis iverified iby ithe isimulation iof ia±160kVVSC-HVdc iMMC iand ithe icomparison iresults iof ithe idc ishort ifault iblocking iand iride ithrough icapability iare ialso iprovided.
