Cúpla Mall: Solúidí Stórála Intile chun Costais a Lasaí, Stádas a Mheabhrú agus Tionchar Forbartha a Chur i bhFeidhm
Ⅰ. Dúshláin Fhuinnimh agus Luach Stórála Fhuinnimh i gCeanntair Siopa
Mar chompleácsa tionsclaíocha éagsúla atá ag úsáid mór fhuinnimh, léiríonn ceanntair siopa carachtar conspóideach úsáid fuinnimh:
- Méid Mhór Meascáin Iarmheán-Airde: Is 3-4 uair níos mó an t-ioncaim leictreach ar feadh lae (mar shampla, 8:00-11:00, 17:00-22:00) ná an t-ioncaim oíche.
- Forcamh Tuarascálaíoch Lódha: Tionchar comhdhúshlánacha ar thosaíocht-stiúrúcháin eochairshuidhmheána mar shampla HVAC (40%), solas (25%) agus stáirsí (15%) a chuirtear i bhfeidhm.
- Forradh Ard ar Stabiliti Leictre: Cineálú ar an gcóras POS, córais slándála agus eochairshuidhmheána réamhse, a chuir go díobháilte forrochtain airgeadais.
Córais stórála fuinnimh laghdóidh costais leictreachta idir 20%–40% agus cothófaidh tionchar ar an grid trí trí gníomh príomha: biorú biorach, rialú éileamh, agus cúnamh éigeandála.

2. Struchtúr Topológach
• Intégráil Fleascach: Tacaíonn le DC coupling le PV gréine nó AC coupling le grid, oiriúnach do tionscadail nua/athchóiriú.
• Iompar Redundancy Ilárach: Córais tine ag obair go neamhspleách (≥3 huaire backup) chun éigríochta évacuation a chinntiú.
Ⅲ. Feidhmeanna Príomha agus Cásaimh Iarratais
1. Forbairt Cothrom na Féinne
• Meascáin Iarmheán-Airde: Luchtaithe ar feadh oíche (0:00-8:00) & leigheas ar feadh lae; IRR sroicheann 13%-20%.
• Rialú Éileamh: Smoothes load curves, reducing transformer capacity fees (for users >315kVA).
• Tionchar Éigeandála: Gníomhaíonn i gcláir peak-shaving grid.
2. Cinntiú Stabachtach
• Seamless Backup: Off-grid switching <10ms; zero interruption for elevators/security systems.
• Optimizing Power Quality: Mitigates voltage sags/harmonics to protect sensitive equipment (e.g., data centers).
3. Green Energy Integration
• PV-Storage-Charging Integration:
o Rooftop solar → ESS stores excess energy → powers EV chargers.
o Boosts renewable self-consumption to 80%, cutting carbon emissions.
