I-Center for Power Electronics and Sustainable Grids iyikhaya lengqalasizinda yocwaningo eyingqayizivele engenakuqhathaniswa emhlabeni wonke. Ngokuxhuma kwaso okuphathelene negridi yamandla kagesi aphezulu angu-110kV kanye ne-transformer engu-40MVA, lesi sikhungo sikuhlomele kahle ukuhlangabezana nezidingo ezikhulayo zama-electronics, okuwubuchwepheshe obubalulekile ekuguquleni uhlelo lwamandla. Ngokuzayo, ugesi ngeke usakhiqizwa ngokuyinhloko yizimboni ezimbalwa zamandla kagesi ezivamile, kodwa kunalokho zizokhiqizwa izimboni eziningi zamandla omoya nelanga akhiqiza ugesi oshintshashintshayo. Ngenxa yalokho, amandla kagesi azodlala indima ebalulekile kuwo wonke amazinga egridi nge-EMS.

Enye yezinselelo ezinkulu ekuthuthukisweni kwesiteshi sikagesi sesikhathi esizayo ukwakhiwa kwezingxenye ze-elekthronikhi zamandla amasha namasistimu anezakhiwo ezithuthukisiwe. Lokhu kudinga ukuqaliswa kwe-silicon carbide kanye ne-gallium nitride power semiconductors, engasebenza kumafrikhwensi aphezulu futhi inike amandla iziguquli zamandla ezinokuminyana kwamandla aphezulu. Ngokusebenzisa lezi zinto ezithuthukisiwe, abacwaningi bahlose ukuthuthukisa ukusebenza kahle nokusebenza kwamandla kagesi, ukuqinisekisa ukuzinza nokulawula ngaphakathi kwegridi yamandla. Ngokusetshenziswa okwandayo kwemithombo yamandla avuselelekayo, kubalulekile ukuba nama-electronics athembekile futhi asebenza kahle ukuze kusekelwe uguquko lwegridi.

Ngaphezu kwalokho, isikhungo sihlose ukuphenya ngezinsizakalo ezintsha zegridi, ngokugxila ngokukhethekile ekuzinzeni kwamagridi asekelwe ku-inverter esikhathini esizayo. Lokhu kuhilela ukuhlola amandla osizo lwegridi ama-inverter, afana ne-voltage nokuzinza kwefrikhwensi. Ukwengeza, isikhungo sizobhekana nezinye izakhiwo, okuhlanganisa ukuncibilika kwe-resonance esebenzayo ezimbonini zikagesi namagridi kagesi. Le mizamo izofaka isandla ekuzinzeni nasekuthembekeni kwegridi ne-EMS, iqinisekise ukuhlanganiswa okushelelayo kwemithombo yamandla avuselelekayo esiteshini samandla kagesi.

Ukuze sithuthukise amakhono aso okucwaninga nentuthuko, isikhungo siphezu kwenqubo yokwakha i-Digital Grid Lab. Le lebhu izogxila ekufanisweni kwamaphrofayili omthwalo nezinhlelo zokuphatha amandla, okuvumela abacwaningi ukuthi baqhubekisele phambili ubuchwepheshe babo ekulingiseni igridi nokuxhumana kwesikhathi sangempela. Ngokuphenya ukusebenza kwamadivayisi nezinhlelo ezindaweni ezibalulekile zegridi, isikhungo sizokwazi ukuthuthukisa ukusetshenziswa kwamandla kagesi kugridi nge-EMS. I-Digital Grid Lab iyintuthuko ebalulekile evela ku-Smart Energy Lab ekhona futhi izotholakala esakhiweni esikhulu se-Fraunhofer ISE.

Sekukonke, iCentre for Power Electronics and Sustainable Grids ihamba phambili ocwaningweni nasekuthuthukisweni emkhakheni wezamandla kagesi. Ngengqalasizinda yaso eyingqayizivele yocwaningo futhi igxile ekuthuthukiseni izingxenye ze-elekthronikhi zamandla, lesi sikhungo simi kahle ukubhekana nezinselele zohlelo lwamandla lwesikhathi esizayo. Ngokwenza ngcono ukusebenza kahle kanye nokuzinza kwezinto zikagesi zikagesi, isikhungo sihlose ukusekela uguquko oluya esiteshini samandla esisekelwe kumandla avuselelekayo. Ukwakhiwa okuqhubekayo Kwelebhu Yegridi Yedijithali kuzothuthukisa amakhono esikhungo futhi kuvumele uphenyo olubanzi mayelana nokusebenza kwamadivayisi namasistimu ngaphakathi kwegridi ye-EMS.
