Njengempahla eyinhloko yokulinganisa amandla ezinhlelweni zamandla, ukuthuthukiswa kobuchwepheshe-kwamamitha wamandla ezigaba ezintathu kuthinta ngokuqondile ukuthembeka nokusebenza kahle kwezomnotho kokusebenza kwegridi. Eminyakeni yakamuva, ngokuthuthukiswa kwamagridi ahlakaniphile, ukuhlanganiswa kwemithombo yamandla emisha, nezinguquko zemakethe yamandla,{2}}amamitha wamandla wezigaba ezintathu enze inqubekelaphambili ebalulekile ekunembeni, ukuhlanganiswa kokusebenza, namandla okuxhumana.
Ngokuphathelene nokunemba kwemitha, amamitha ajwayelekile e-electromechanical three-esigaba samandla athathelwa indawo awawase-elekthronikhi. Amamitha kagesi asebenzisa{2}}i-analogi enembayo-kuya{4}}kuya{4}}iziguquli zedijithali nobuchwepheshe bokucubungula isignali yedijithali, okwenza amaphutha okulinganisa alawulwe ngaphakathi kuka-0.1%, okwedlula kakhulu u-0.5%-2% wamamitha e-electromechanical. Ngaphezu kwalokho, amazinga omhlaba (afana ne-IEC 62053) alawula ngokuqinile amazinga okunemba kwamamitha wamandla ezigaba ezintathu, ashayela abakhiqizi ukuthi bathuthukise ukwakheka kwesekethe nezindlela zokulinganisa.
Ukuhlanganiswa okusebenzayo kungenye inkambiso ebalulekile. Amamitha wamandla ezigaba ezintathu-zezigaba ezintathu zesimanje awanikezi nje kuphela imisebenzi eyisisekelo yokulinganisa amandla kodwa futhi ahlanganisa izici ezithuthukile njengokuhlaziywa kwe-harmonic, ukutholwa kwe-voltage sag, kanye nokurekhoda kwephrofayela yokulayisha. Isibonelo, amanye amamitha kagesi aphezulu-angaqapha{4}}ukungalingani kwezigaba ezintathu ngesikhathi sangempela futhi asebenzise ama-algorithms ukunxephezela amaphutha okulinganisa abangwe ukuchezuka kwesigaba. Ngaphezu kwalokho, ukusetshenziswa kwama-microprocessors kanye nezinhlelo ezishumekiwe kwenza amamitha kagesi enze ukucubungula idatha yendawo, okusekela ukuphathwa kwamandla asabalalisiwe.
Intuthuko kubuchwepheshe bezokuxhumana ithuthukise kakhulu ubuhlakani-kwamamitha kagesi wezigaba ezintathu. Amasistimu okufunda amamitha akude asekelwe kusiphathi selayini yamandla (PLC), ifrikhwensi yomsakazo (RF), kanye nokuxhumana kwe-fiber optic sekuyinto evamile, esekela{2}}ukudluliswa kwedatha yesikhathi sangempela nesilawuli kude. Eminyakeni yakamuva, ukwethulwa kwe-narrowband Internet of Things (NB-IoT) kanye nobuchwepheshe be-5G kuye kwanciphisa ukubambezeleka kokuxhumana futhi kwathuthukisa ukuphendula okuguquguqukayo kwegridi yamandla. Ngaphezu kwalokho, ubuchwepheshe bokuphepha benethiwekhi obuthuthukisiwe (njengama-algorithms wokubethela kanye nokuqinisekisa ubuwena) buqinisekisa ubuqotho kanye nokuphazamisa{7}}ubufakazi bedatha yemitha.
Ucwaningo lwangomuso-kumamitha kagesi wezigaba ezintathu luzogxila{1}}ekubuchwepheshe benzwa obunembayo,{2}}ukulinganisa okudidiyelwe kwamandla kaningi (njengogesi odidiyelwe, amasistimu okushisa, negesi), kanye nokuqagela iphutha eliqhutshwa yi-AI{3}}. Njengoba ingxubevange yamandla omhlaba ishintsha,-amamitha kagesi wezigaba ezintathu azoqhubeka athuthukele ekuthembekeni okuphezulu,{6}}ekusebenzeni okuningi, kanye namanethiwekhi, abeka isisekelo sokwenziwa kwedijithali kwamagridi ahlakaniphile.
