Nrog rau kev txhim kho ntawm cov thev naus laus zis tshiab thiab cov teeb meem ib puag ncig thoob ntiaj teb, nce kev siv lub zog huv xws li hnub ci thiab cua zog tau dhau los ua ib qho ntawm peb lub sijhawm. Hauv tsab xov xwm no, peb yuav tsom mus rau txoj kev siv lub hnub ci zog thiab qhia koj yuav ua li cas rau kev tshawb fawb tsim qhov zoo tshaj plawsroj teeb thaub qab fais fab rau tsev. 
Cov kev xav tsis zoo thaum tsim Lub Tsev Hluav Taws Xob Cia Hluav Taws Xob 1. Tsom ntsoov rau lub peev xwm roj teeb xwb 2. Standardization ntawm kW / kWh piv rau txhua daim ntawv thov (tsis muaj qhov sib piv rau txhua qhov xwm txheej) Txhawm rau kom ua tiav lub hom phiaj ntawm kev txo qis tus nqi hluav taws xob nruab nrab (LCOE) thiab nce kev siv hluav taws xob, ob lub ntsiab lus tseem ceeb yuav tsum tau xav txog thaum tsim lub zog cia hauv tsev rau kev siv sib txawv: PV system thiabtsev roj teeb thaub qab system. TXOJ HAUJ LWM NTAWM PV SYSTEM thiab lub tsev roj teeb thaub qab SYSTEM yuav tsum tau coj mus rau hauv tus account cov ntsiab lus hauv qab no. 1. Solar Radiation Level Qhov kev siv ntawm lub hnub ci hauv zos muaj kev cuam tshuam zoo rau kev xaiv PV system. Thiab los ntawm kev xav ntawm kev siv hluav taws xob, lub peev xwm tsim hluav taws xob ntawm PV system yuav tsum ua kom txaus los npog cov khoom siv hluav taws xob hauv tsev niaj hnub. Cov ntaub ntawv hais txog kev siv lub hnub ci hauv cheeb tsam tuaj yeem tau txais los ntawm Is Taws Nem. 2. Kev Ua Haujlwm Zoo Feem ntau hais lus, ua tiav PV lub zog cia qhov system muaj lub zog poob ntawm 12%, uas feem ntau yog ● DC/DC conversion efficiency poob ● Roj teeb them / tso tawm lub voj voog ua haujlwm poob ● DC/AC conversion efficiency poob ● AC charging efficiency poob Kuj tseem muaj ntau yam kev poob qis thaum lub sijhawm ua haujlwm ntawm lub kaw lus, xws li kev sib kis tsis zoo, kab poob, kev tswj tsis tau, thiab lwm yam. Yog li ntawd, thaum tsim lub PV lub zog cia qhov system, peb yuav tsum xyuas kom meej tias cov roj teeb tsim tau tuaj yeem ua tau raws li qhov xav tau tiag tiag. ntau li ntau tau. Xav txog qhov poob ntawm lub zog tag nrho, lub peev xwm ntawm lub roj teeb yuav tsum yog Qhov yuav tsum tau muaj roj teeb muaj peev xwm = tsim roj teeb muaj peev xwm / system efficiency 3. Lub Tsev Roj Teeb Backup System Muaj peev xwm Cov "pob roj teeb muaj peev xwm" thiab "muaj peev xwm" nyob rau hauv lub roj teeb parameter cov lus yog cov ntaub ntawv tseem ceeb rau kev tsim lub zog cia hauv tsev. Yog tias qhov muaj peev xwm tsis tau qhia hauv cov roj teeb tsis muaj, nws tuaj yeem suav los ntawm cov khoom ntawm lub roj teeb qhov tob ntawm qhov tso tawm (DOD) thiab lub peev xwm roj teeb.
| Roj teeb Performance Parameter | |
|---|---|
| Muaj peev xwm tiag | 10.12 kWh |
| Muaj peev xwm | 9,8k wb |
Thaum siv lub txhab nyiaj lithium roj teeb nrog lub zog cia inverter, nws yog ib qho tseem ceeb uas yuav tsum tau them sai sai rau qhov tob ntawm cov pa tawm ntxiv rau qhov muaj peev xwm, vim tias qhov preset qhov tob ntawm qhov paug tawm yuav tsis zoo ib yam li qhov tob ntawm qhov tso tawm ntawm lub roj teeb nws tus kheej. Thaum siv nrog lub zog tshwj xeeb cia inverter. 4. Parameter Matching Thaum tsim ibtsev zog cia system, nws yog ib qho tseem ceeb heev uas tib yam tsis tau ntawm lub inverter thiab lithium roj teeb lub txhab nyiaj yog matched. Yog tias qhov ntsuas tsis sib xws, lub kaw lus yuav ua raws li tus nqi me dua los ua haujlwm. Tshwj xeeb tshaj yog nyob rau hauv standby fais fab hom, tus tsim qauv yuav tsum xam lub roj teeb nqi thiab tawm tus nqi thiab lub hwj chim mov muaj peev xwm raws li tus nqi qis. Piv txwv li, yog tias lub inverter qhia hauv qab no sib phim rau lub roj teeb, qhov siab tshaj plaws them / tawm tam sim no ntawm lub kaw lus yuav yog 50A.
| Inverter Parameters | Roj teeb Parameters | ||
|---|---|---|---|
| Inverter Parameters | Roj teeb Parameters | ||
| Roj teeb input parameters | Hom kev ua haujlwm | ||
| Max. Charge voltage (V) | ≤60 | Max. them tam sim no | 56A (1C) |
| Max. them tam sim no (A) | 50 | Max. tso tawm tam sim no | 56A (1C) |
| Max. tso zis tam sim no (A) | 50 | Max. luv-circuit tam sim no | 200 A |
5. Daim ntawv thov Scenarios Daim ntawv thov scenarios kuj yog ib qho tseem ceeb rau kev txiav txim siab thaum tsim lub zog cia hauv tsev. Feem ntau, cov khoom siv hluav taws xob hauv tsev tuaj yeem siv los ua kom tus kheej siv tus kheej ntawm lub zog tshiab thiab txo cov hluav taws xob yuav los ntawm daim phiaj, lossis khaws cov hluav taws xob tsim los ntawm PV ua lub tsev roj teeb thaub qab. Sijhawm-ntawm-siv Roj teeb thaub qab fais fab rau tsev Kev tsim tus kheej thiab kev siv tus kheej Txhua qhov scenario muaj qhov sib txawv tsim logic. Tab sis tag nrho cov qauv tsim qauv kuj yog raws li kev siv hluav taws xob hauv tsev tshwj xeeb. 
Sijhawm-ntawm-siv tariff Yog tias lub hom phiaj ntawm lub roj teeb thaub qab rau lub tsev yog txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau tiv thaiv tus nqi hluav taws xob siab, cov ntsiab lus hauv qab no yuav tsum raug sau tseg. A. Lub Sijhawm Sib Tham (peaks thiab hav ntawm cov nqi hluav taws xob) B. Kev siv hluav taws xob thaum lub sij hawm siab tshaj (kWh) C. Kev siv hluav taws xob txhua hnub (kW) Qhov zoo tshaj plaws, lub peev xwm muaj peev xwm ntawm cov roj teeb lithium hauv tsev yuav tsum siab tshaj qhov xav tau ntawm lub zog (kWh) thaum lub sij hawm ncov. Thiab lub zog muaj peev xwm ntawm qhov system yuav tsum siab tshaj qhov kev siv hluav taws xob txhua hnub (kW). 
Roj teeb Backup Fais Fab rau Tsev Nyob rau hauv lub tsev roj teeb backup system scenario, lubtsev lithium roj teebyog them los ntawm PV system thiab kab sib chaws, thiab tso tawm kom tau raws li qhov xav tau ntawm kev thauj khoom thaum lub caij sib tsoo. Txhawm rau kom ntseeg tau tias cov khoom siv hluav taws xob yuav tsis cuam tshuam rau lub sijhawm hluav taws xob, nws yog ib qho tsim nyog yuav tsum tsim kom muaj lub zog txuag hluav taws xob los ntawm kev kwv yees lub sijhawm ntawm cov hluav taws xob hluav taws xob ua ntej thiab nkag siab txog tag nrho cov hluav taws xob siv los ntawm tsev neeg, tshwj xeeb tshaj yog cov kev xav tau ntawm siab loads. 
Self-generation thiab Self-consumption Daim ntawv thov scenario no aims los txhim kho tus kheej tiam thiab tus kheej-siv tus nqi ntawm PV system: thaum lub PV system generates txaus lub hwj chim, lub tsim hwj chim yuav muab nkag mus rau lub load ua ntej, thiab cov tshaj yuav muab cia rau hauv lub roj teeb kom tau raws li. qhov kev thov thauj khoom los ntawm kev tso lub roj teeb thaum lub PV system tsim lub zog tsis txaus. Thaum tsim cov khoom siv hluav taws xob hauv tsev rau lub hom phiaj no, tag nrho cov hluav taws xob siv los ntawm tsev neeg txhua hnub raug coj mus rau hauv tus account kom ntseeg tau tias cov hluav taws xob tsim los ntawm PV tuaj yeem ua tau raws li qhov xav tau ntawm hluav taws xob. Kev tsim ntawm PV lub zog cia tshuab feem ntau yuav tsum xav txog ntau yam kev thov kom tau raws li lub tsev xav tau hluav taws xob nyob rau hauv ntau qhov xwm txheej. Yog tias koj xav tshawb nrhiav cov ncauj lus kom ntxaws ntxiv ntawm cov qauv tsim, koj xav tau cov kws tshaj lij lossis cov neeg tsim khoom tsim los muab kev txhawb nqa kev tshaj lij. Nyob rau tib lub sijhawm, kev lag luam ntawm cov khoom siv hluav taws xob hauv tsev kuj yog ib qho kev txhawj xeeb tseem ceeb. Yuav ua li cas kom tau txais txiaj ntsig zoo ntawm kev nqis peev (ROI) lossis seb puas muaj kev txhawb nqa txoj cai zoo sib xws, muaj kev cuam tshuam zoo rau kev xaiv tsim ntawm PV zog cia system. Thaum kawg, xav txog kev loj hlob yav tom ntej ntawm kev xav tau hluav taws xob thiab qhov tshwm sim ntawm kev txo qis peev txheej vim kev kho vajtse lub neej lwj, peb pom zoo kom ua kom muaj peev xwm ua tau zoo thaum tsim khoom.roj teeb thaub qab fais fab rau tsev daws teeb meem.
