Kugeza ubu, hamwe n’iterambere ry’imibereho n’ubukungu, ritangiza imitwaro myinshi idafite umurongo muri gride y’amashanyarazi, ariko kandi ikazana ihindagurika ry’amashanyarazi ya gride, impande zombi zikoresha ingufu nkeya, kutaringaniza imbaraga za voltage, ibintu bihuza, nkurwego rwubwiza bwamashanyarazi ibibazo.Kubera iyo mpamvu, haba mu gihugu ndetse no mu mahanga bashyize mu bikorwa ibibazo bitanga ingufu za static var generator (Static Var Generator).Ubwoko bwa SVG bushyigikira uburyo bwihariye bwo guhuza ibikorwa nka sisitemu ya SVG igice cyingenzi, ifite impedance nini, kunoza ifite transformateur yubushobozi bwo kurwanya imiyoboro ngufi, kandi transformateur yakoreshejwe ifite uburyo bushya bwo gutunganya inzira, reka ibifite umwihariko wibiranga guhuza: inshuro II kuzunguruka igipimo rusange cyo kugoreka ibintu byose ntabwo birenze 10%, ibyo inshuro 2 ntabwo birenze 4%, inshuro 3 ninshuro 4 ntabwo birenze 2%, ikindi gihe ntabwo kirenze 1%.
