Lapho 'isitoreji samandla esakha igridi' ngokuzumayo saba yindaba enkulu ezingxoxweni mayelana nohlelo olusha lwamandla, olubhekwa ngisho 'njengomkhawulo wobuchwepheshe' wokuhlanganiswa kwegridi yamandla avuselelekayo, imizwa yemakethe yaqala ngokushesha. Ngokuphikisana nesizinda sokukhula okuqhubekayo kwamazinga okungena kwamandla avuselelekayo kanye nezakhiwo zokusetshenziswa kukagesi ezishintshashintshayo, ikhono lokwakha igridi aliyona nje umqondo wokumaketha kodwa liyisinqumo esingenakugwenywa ngemuva kokushintsha okukhulu kwendlela yokusebenza kwegridi.

I. Ingcindezi Yangempela Ebhekene Nohlelo Olusha Lwamandla: Hhayi 'Ukuthi Kukhona Amandla', Kodwa 'Ukuthi Azinzile'

Ukuhlanganiswa okukhulu kwemithombo yamandla emisha njenge-photovoltaics kanye namandla omoya, kuhlanganiswe nokukhishwa kancane kancane kwamajeneretha endabuko ahambisanayo, kushintsha ngokuyisisekelo izici zokusebenza kohlelo lwamandla:

I-inertia yesistimu iyaqhubeka nokwehla

Izingozi zokuphambuka kwemvamisa yegridi ziyanda

Ukusekelwa kwamandla asebenzayo akwanele, ukuqina kwamandla kagesi kuyacindezela

Kwezinye izindawo ezintsha zokuhlanganisa amandla, izinkinga ezintsha ezifana nokuguquguquka kwemvamisa ebanzi sezivele zivele

Ikakhulukazi, iphethini yokukhipha ngezikhathi ezithile yezinhlelo ze-photovoltaic - ekhiqiza ngezikhathi zasemini futhi iphele ebusuku - ikhulisa kakhulu imithwalo yokulawula ukucheba okuphezulu kanye nokuvama kwegridi.

Inkinga ayikho ekwandeni kwamandla okukhiqiza, kodwa 'ekubuthaka kwamakhono okusekela' egridi.

Njengoba ochwepheshe bemboni bephawulile: 'Ugesi akumelwe ukhiqizwe kuphela, kodwa futhi udluliselwe ngendlela ethembekile nehlala isikhathi eside.'

Yingakho nje isitoreji samandla esakha igridi sibekwe endaweni evelele.

II. Ukwakhiwa kwegridi ngaphandle kokugcina amandla kuyisisombululo esiyingxenye kuphela

Kusalokhu kukhona umbono ongalungile ovamile ezingxoxweni zemboni:

Ukuthuthukisa ama-algorithms e-inverter kuphela kubhekwa njengokwanele ekwenzeni igridi.

Kodwa ngokombono we-logic yokusebenza kwesistimu yamandla, lokhu kuqonda kwenziwe lula kakhulu.

Izinhlelo ze-photovoltaic zendabuko kanye nezamandla omoya zisebenzisa kakhulu ukulawula okulandela igridi, ezisebenza ngemodi ye-Maximum Power Point Tracking (MPPT). Ngokuyinhloko zisebenza 'njengemithombo yamanje'—

Uma imvamisa yegridi yehla, ayikwazi ukwandisa amandla asebenzayo ngokuqhubekayo, okwenza ingafaneleki imisebenzi yokusekela imvamisa kanye ne-voltage.

Ngakho-ke, ngaphandle kokugcinwa kwamandla, lokho okubizwa ngokuthi 'i-grid-forming PV' kungabhekwa kuphela 'njengokwakha igridi ngokwengxenye'.

Ezinhlelweni zamandla ezintsha zanamuhla, isitoreji se-electrochemical esinekhono lokushaja/ukukhipha ngokushesha eliqondiswe kabili yisona kuphela isisetshenziswa esikwazi ukuphendula ezingeni le-millisecond futhi sisungule i-voltage kanye nemvamisa ngenkuthalo.

III. Ukuhlola 'Amandla Okwakha Igridi Yangempela': Ubunikazi Nokusebenza Komzimba

Phakathi kokudideka komqondo wemakethe, umuntu angayibona kanjani indawo yokugcina igridi esebenza kahle ngempela?

Kuvele izilinganiso ezimbili zokuhlola ezisekelwe ekuvumelaneni embonini:

1 Hlola 'Ubunikazi': Ingabe umthombo we-voltage?

Lokhu kwakha umkhawulo wokungena.

Ingabe isebenzisa ubuchwepheshe be-Virtual Synchronous Generator (VSG)?

Ingabe ifake izibalo zokunyakaza kwe-rotor kanye ne-logic yokulawula i-droop yama-generator ahambisanayo?

Kuphela ngokufinyelela izici 'zomthombo we-voltage' ngokusebenzisa i-control logic lapho imishini inekhono eliyisisekelo lokusungula ngokuzimela i-grid voltage kanye ne-frequency.

2 Hlola 'Amandla Omzimba': Ingabe ingawuthwala umthwalo?

Umehluko wangempela ulele emandleni okusekela ezingeni lehadiwe:

Ingabe umthamo wokulayisha ngokweqile usondela emazingeni ejeneretha ahambisanayo?

Ingabe impendulo yamandla ishesha ngokwanele?

Ingabe umkhiqizo ozinzile ungagcinwa ngaphansi kwezimo zamaphutha?

Imikhiqizo eminingi 'yakha amagridi ngokwe-algorithm' kodwa 'iyawa ngaphansi komthwalo' ekusebenzeni kwangempela. Inkinga ayikho ku-topology, kodwa ku-redundancy yobunjiniyela kanye nomklamo wesistimu.

IV. Ukuletha 'Inani Lokwakha Igridi' Ngokusebenzisa Amandla Obunjiniyela

Njengoba isitoreji esakha igridi sishintsha sisuka 'ebufakazini bomqondo' siye 'ekusetshenzisweni okukhulu,' Highjoule(HJ Group) ibeka phambili ukuvumelanisa amakhono okwakha igridi namagridi akhona kunokuphoqelela ukuguqulwa kwegridi kwemishini.

✔ Indlela yokuzivumelanisa negridi eqinile

Izinhlelo zokugcina igridi ezisebenzisa ukulawulwa komshini ovumelanisiwe okubonakalayo ukuze zilingise izici ze-voltage kanye nemvamisa zejeneretha ezivumelanisiwe zendabuko. Kumodi yokwakha igridi, zisungula izinkomba ze-voltage kanye nemvamisa ngokuqhubekayo, zinikeza ukwesekwa kwegridi okubalulekile.

✔ Amandla Okulayisha Okukhulu Nokuphendula Okusheshayo

Umklamo wehadiwe ubhekana ngokuphelele nezidingo zesikhashana zokushaqeka kwegridi, okubonisa ukubekezelela okuphezulu kokulayishwa ngokweqile kanye nokuphendula kwamandla ezingeni le-millisecond. Lokhu kwenza kube lula ukungenelela okusheshayo ngesikhathi sokuwa kwamandla, ukuphazamiseka kwemvamisa, kanye nezinye izimo zokusebenza ukuze kuqiniswe ukusebenza kwesistimu.

✔ Ukulawulwa Kwemvamisa kanye Nokushefa Okuphezulu Kwezimo Ezivuseleleka Kakhulu

Ukusebenzisa ukulawulwa kwamandla asebenzayo okuqondiswa yizinhlangothi zombili, HighjouleIzinhlelo ze-(HJ Group) zihlinzeka ngasikhathi sinye:

Ukusekelwa kwe-Iertia

Ukulawulwa Kwemvamisa Eyinhloko

Ukushefa okuphezulu kanye nokunciphisa umthwalo

Ukuqala okumnyama nokusebenza okugcwele iziqhingi

Isebenza ngempela 'njengesiqinisi' ezimweni lapho amandla avuselelekayo aphezulu khona.

V. Kusukela Kugridi Kuya Kumandla Ekhompyutha: Imingcele Yesicelo Esisha Yokugcina Amandla Okwakha Igridi

Ngokwanda okusheshayo kwezikhungo zokubala ze-AI, ukusetshenziswa kwamandla akugcini nje ngokwanda kwevolumu kodwa futhi kudlula nezinguquko eziguquguqukayo.

Ukuguquguquka kwamandla ezingeni le-Millisecond okudalwe amaqoqo e-GPU ngesikhathi sezinqubo zokucabanga nokuqeqesha sekuqala ukuthinta izikhungo zedatha ngisho nohlangothi lwegridi.

Isitoreji samandla esakha igridi sivela njengesendlalelo se-buffer esixhuma igridi ngemithwalo eshintshashintsha kakhulu.

Ukusebenzisa ubuchwepheshe bayo kwezobuchwepheshe ku-HVDC kanye nezinhlelo zokugcina amandla, Highjoule(HJ Group) ingasebenzisa izinhlelo zokugcina amandla ezakha igridi ohlangothini lokuphakelayo kwe-AC:

Ukushintshashintsha kwemithwalo yokubala

Ukunciphisa imithelela yegridi

Ukunciphisa ukucushwa kwesitoreji esinezigaba eziningi ezindaweni zokugcina

Ukuthuthukisa ukusebenza kahle kwesistimu iyonke

Njengoba amapulatifomu angu-800V kanye ne-voltage ephezulu eba yinto evamile, inani lesistimu yesitoreji samandla esakha igridi lizokhuliswa kakhulu.

VI. Amandla okwenza igridi akuyona ilebula, kodwa umphumela wobuchule bobunjiniyela besikhathi eside

Ngaphakathi kokuthuthukiswa kwezinhlelo ezintsha zamandla, isitoreji samandla esakha igridi ngeke sibe 'umkhuba wesikhathi esifushane', kodwa sizoqhubeka siguquke sibe yisidingo samandla ayisisekelo.

Amandla okwakha igridi langempela adlula nje ukufakwa ohlwini lwemininingwane; achazwa yi:

Ukubhekana nezimo zokusebenza eziyinkimbinkimbi

Ukuhlanganiswa okungenamthungo kwezakhiwo zegridi ezikhona

Ukusebenza okuzinzile nokuqhubekayo ngezinga

Highjoule(HJ Group) ihlala igxile ekusebenzeni kobunjiniyela, iguqula ukwakha igridi kusuka emqondweni ibe yizixazululo ezisebenzayo ngokusebenzisa amasu okulawula aqinisekisiwe, ukwakheka kwehadiwe okuqinile, kanye nezimiso zokuphepha ezingeni lesistimu.
