Ithuluzi elibonakala lingacacile kodwa elibalulekile cishe yonke indawo emphakathini wanamuhla: imitha kagesi. Leli bhokisi lensimbi, elifakwe ebhokisini lokusabalalisa lendlu noma egumbini lokusabalalisa ugesi lebhizinisi, lirekhoda buthule konke ukuhamba kukagesi, libe isixhumanisi esibalulekile phakathi kwabasebenzisi nesistimu kagesi. Imitha kagesi ingaphezu nje kwethuluzi lokulinganisa elilula; kuyingxenye ebalulekile yohlelo lwesimanje lokuphatha amandla, futhi ukuvela kwalo kukhombisa ukuguquka kwendlela esisebenzisa ngayo amandla.
Umsebenzi oyisisekelo wemitha kagesi ukulinganisa ngokunembile ukusetshenziswa kwamandla, okuvame ukuboniswa ngama-kilowatt-amahora (kWh). Lapho i-current igeleza kumitha, izakhi zomshini noma ze-elekthronikhi ngaphakathi kwayo zibala amandla asetshenziswa ngokuphindaphinda i-voltage ne-current, futhi iqongelela futhi igcine leli nani. Amamitha omshini ovamile ancike kudiski ye-aluminium ezungezayo eshayela isondo ledijithali ukuze ibonise ukufundwa. Amamitha ahlakaniphile esimanje, nokho, asebenzisa ubuchwepheshe be-microelectronics obuthuthukisiwe, obuvumela ukulinganisa okunembe kakhudlwana kanye{4}}nokuxhumana ngezindlela ezimbili. Kungakhathaliseki ukuthi ikhanyisa ikhaya, isebenzisa i-air conditioner, noma isebenzisa ulayini wokukhiqiza wefekthri noma isikhungo sedatha, imitha ngokuqhubekayo irekhoda ukuthi ukuphi wonke ama-kilowatt{6}}amahora kagesi. Amamitha kagesi eza ngezinhlobo eziningi ezahlukene, ngalinye linezici zalo ezihlukile. Imitha eyimishini ejwayeleke kakhulu isebenzisa induction ye-electromagnetic, izungeza idiski ye-aluminium ngokusebenzisana kwe-magnetic flux ekhiqizwa ikhoyili yamanje kanye nekhoyili ye-voltage. Nakuba ilula ngesakhiwo futhi ithembekile kakhulu, iphinde inikeze ukusebenza okulinganiselwe. Amamitha kagesi asebenzisa amasekhethi ahlanganisiwe ezibalo zedijithali, anikeza ukunemba okuphezulu kanye nokuvikeleka kokuphazamiseka okuthuthukisiwe. Angakwazi futhi ukukala ububanzi obubanzi bemingcele yamandla, njengesici samandla nokuguquguquka kwe-voltage. Amamitha akhokhelwa kusengaphambili avumela abasebenzisi ukuthi bagcwalise i-akhawunti yabo ngaphambi kokusebenzisa ugesi, okuxazulula ngempumelelo inkinga yokuqoqwa kwezikweletu. Amamitha ahlakaniphile, isizukulwane sakamuva semikhiqizo, anikezi kuphela ukufundwa kwamamitha okuzenzakalelayo okukude,{14}}ukuqapha kwesikhathi sangempela, nokulawula ukulayisha, kodwa futhi ahlanganisa kalula namasistimu ahlakaniphile asekhaya, anikeze abasebenzisi imibiko enemininingwane yokuhlaziywa kokusetshenziswa kwamandla nezincomo{15}}zokonga. Amamitha wezimboni asebenza ngezindlela eziningi angakala amapharamitha akhethekile njengama-harmonics nesidingo, ahlangabezane nezidingo zokuqapha zezindawo eziyinkimbinkimbi zokusetshenziswa kwamandla.
Amamitha kagesi adlala izindima ezibalulekile eziningi emphakathini wanamuhla. Ezinkampanini zikagesi, amamitha kagesi ayisisekelo sokukhokhisa. Ukulinganisa okunembile kuqinisekisa uhlelo lokukhokhisa olunobulungiswa nolusobala. Kubasebenzisi, amamitha ahlinzeka ngedatha yokusetshenziswa kukagesi enembile, ekhuthaza amandla{3}}okugcina ukuqwashisa nokuhlonza amaphethini okusetshenziswa angajwayelekile. Kubaphathi begridi, inani elikhulu ledatha elikhiqizwa amanethiwekhi amamitha ahlakaniphile linikeza ukwesekwa kwesayensi kokufunwa{5}} kokuphathwa kohlangothi, ukuqagela amaphutha, nokuhlelwa kwegridi. Kumongo wenguquko entsha yamandla, amasistimu we-photovoltaic asabalalisiwe nawokugcina amandla asebenzisana kakhulu namamitha kagesi. I-Bidirectional metering yenza "ama-prosumers" (kokubili abathengi nabakhiqizi) ukubala ngokunembile izinzuzo zokubeka ugesi osele ku-inthanethi. Ukumbiwa okujulile kwedatha yamamitha kungaphinda kuveze amaphethini okusetshenziswa kukagesi wesifunda, kunikeze isisekelo sokuthatha{9}}isinqumo ekuthuthukisweni kwedolobha elihlakaniphile kanye nokuguqulwa kwezimakethe zamandla.
Ngokuthuthukiswa kwe-inthanethi Yezinto kanye nobuchwepheshe bobuhlakani bokwenziwa, amamitha kagesi abhekana noshintsho olukhaliphile olungakaze lubonwe. Isizukulwane esisha samamitha ahlakaniphile asinikezi kuphela amandla okufunda imitha okuzenzakalelayo okukude kanye{1}}nempendulo yentengo yesikhathi sangempela, kodwa futhi sisebenzisa ama-algorithms okufunda ngomshini ukuhlaziya imikhuba yokusetshenziswa komsebenzisi futhi sinikeze izixazululo zokonga zamandla{2}. Ekulungisweni kwemakethe yamandla, idatha yamamitha isiphenduke isignali ebalulekile ebonisa ubudlelwano bangempela bokunikezwa nesidingo, okusekela ukuqaliswa kwezinqubo zentengo eziguquguqukayo njengesikhathi-sokusebenzisa{5}}kanye nenani eliphakeme{6}}lokukhuphuka kwentengo. Ukusetshenziswa kobuchwepheshe be-cybersecurity kuqinisekisa ukuvikeleka nokuthembeka kwezixhumanisi zokuxhumana zamamitha kagesi, kuvinjwe ukuhlaselwa okunonya kanye nokuphazanyiswa kwedatha. Ngokuzayo, ngokuhlanganiswa kobuchwepheshe obufana ne-5G kanye ne-edge computing, amamitha kagesi azoshintsha abe izindawo ezihlakaniphile ku-Energy Internet, afinyelele impendulo yeleveli ye-millisecond{10}}nokulawulwa kokuhlanganyela okusabalalisiwe, abeke isisekelo sokwakha isistimu yamandla yesimanje ehlanzekile, ephansi{11}yekhabhoni, ephephile, nesebenza kahle.
Imitha kagesi encane iphethe ubuhlakani obukhulu bokuphatha amandla. Kusukela ekuqaleni kwayo okuthobekile njengethuluzi lokukala elilula kuya endimeni yalo yamanje njengendawo yokuqoqa idatha, ukuvela kwemitha kagesi kuveza umgomo wabantu wokusebenzisa amandla ngendlela ephumelelayo, ehlakaniphile, kanye nesimeme. Uma sihlola ukufundwa kwamamitha ethu njalo ngenyanga, sibamba iqhaza ngempumelelo kunguquko yamandla yomhlaba wonke{2}}ekhuthaza ukusetshenziswa kukagesi okunengqondo ngokulinganisa okunembile kanye nokushayela ukuguqulwa kwamandla ngokubonisa ngale kwedatha. Ukuqonda ukusebenza nokusetshenziswa kwamamitha kagesi akusizi nje kuphela ukuphatha kangcono izindleko zamandla asekhaya kodwa futhi kukhombisa umthwalo wemfanelo nokuqwashisa okufanele zonke isakhamuzi sanamuhla sibe nakho ekubambeni iqhaza ekuthuthukisweni okusimeme. Phakathi kwegagasi loguquko lwamandla, amamitha kagesi azoqhubeka nokuvikela ukusatshalaliswa okunembile kokukhanya namandla ngendlela yawo eyingqayizivele.
