Kongera inyungu ku nguzanyo: Kugabanya TCO ukoresheje ibikorwa remezo bya BESS

Igisubizo cyihuse

Ububiko bw'ingufu za batiri (BESS) butuma inyungu ku ishoramari ry'ahantu hakoresha ingufu za DC ziyongera mu kwibasira ibintu bitatu binini bitwara amafaranga menshi mu bijyanye n'ikiguzi cy'umutungo (TCO): amafaranga yo gusaba, kugura ingufu, n'amafaranga yo guhuza grid. Ku gice gisanzwe cya 480 kW gikoresha ingufu ziyongera, amafaranga yo gusaba yonyine ashobora kuba 30-70% by'amafaranga y'amashanyarazi ya buri kwezi; BESS ifite ingano ikwiye igabanya ayo mafaranga, igahindura ibyo yaguze mu masaha atari ay'igihe kinini, kandi igatuma aho hantu hasubikwa cyangwa hagaburwa uburyo bwo kuvugurura transformer busanzwe butwara hagati ya 50.000 na 200.000 by'amadolari y'Amerika. Igihe cyo kwishyura ibikorwa remezo byo gusaba umuriro bya BESS gikunze kuba kiri hagati y'imyaka 4-7 ugereranije n'imyaka 8-12 ku bwubatsi bwa grid gusa, mbere yo kubara inyungu zo kwihanganira no gukora akazi. Kubwibyo, kongera ROI bitangirira ku mbonerahamwe y'igishushanyo: ingano y'ububiko ukurikije umuvuduko nyawo w'umutwaro, ntabwo ari ugereranije n'imbaraga za charger zashyizweho.

Ibintu by'ingenzi byakunzwe

• Amafaranga yo gukenera, atari ingano y'ingufu, ni yo yiganjemo ikiguzi cyo gukoresha DC fast charge — BESS peak shaving niyo lever ifite akamaro kanini ya TCO.
• Guhuza imiyoboro y'amashanyarazi n'ivugurura rya transformer akenshi ni byo bikunze kuba umurongo munini wa capex; BESS irabigabanya cyangwa ikabisubika.
• Ingufu zikoreshwa mu gukata no kuzikoresha imirasire y'izuba byongera inyungu/igiciro cya kabiri hejuru y'uburyo bwo kogosha buhanitse.
• Ibyemezo bya Opex — imicungire y’ubushyuhe, kwangirika kwa bateri, imicungire ya OCPP, n’amasezerano yo kubungabunga — bigena mu buryo bucece TCO y’imyaka 10.
• Uburyo bwo gutanga inyungu ku isoko (ROI models) bugomba kugereranya urubuga n'umurongo ngenderwaho warwo gusa, hanyuma bugapima uburyo bwo kwishyura ku mushinga w'inyongera, atari ku mushinga wose.

Imiterere y'Ibiciro Abakoresha benshi bakora nabi

Sitasiyo ya DC ikoresha ingufu zihuta ya 480 kW ntabwo ikunze kuba umukoresha wa 480 kW. Umutwaro wo gushyushya imodoka n'imodoka rusange ni nk'umuhengeri: umuhanda munini ushobora gukoreshwa hagati ya 30-40% ariko ugakoresha ingufu zose mu minota 15-30 iyo imodoka esheshatu zishyushya icyarimwe. Ibyuma bitanga umuriro byishyura amafaranga menshi, atari impuzandengo, binyuze mu kiguzi cy'ubusabe - ubusanzwe hagati ya 5-20 USD kuri kW ku kwezi hiyongereyeho ingufu z'amashanyarazi. Ubwiyongere bw'ubusabe bwa 480 kW bwashoboraga kugabanuka bukagera kuri 240 kW butwara umukoresha hagati ya 1,400-5,800 USD ku kwezi mu kiguzi gishobora kwirindwa, ari cyo hagati ya 17,000-70,000 USD ku mwaka kuri metero imwe.

Iyi ni yo mpamvu ubukungu bwo gushyushya amashanyarazi gusa bugwa ku rugero runini: iyo ushyizeho charger nyinshi zifite ingufu nyinshi, curve y’ibikenewe yiyongera vuba kurusha uko amafaranga yinjiza. Ububiko bwa batiri bugabanya iyo curve. BESS ishyushya ijoro ryose ku gipimo cy’ingufu kitari icy’ingenzi, hanyuma irasohoka mu gihe cy’igihe kinini cy’urubuga, bigatuma igipimo cy’ibikenewe kigera ku rwego rw’ubwumvikane. Imibare ni iy’ukuri - ntabwo ishingiye ku biciro by’ingufu bihindagurika cyangwa inkunga ya leta - ibi bigatuma iba ishingiro ry’icyitegererezo icyo ari cyo cyose cyizewe cya TCO.

Imiterere ya TCO: Aho amafaranga anyura mu myaka irenga 10

TCO y'aho amashanyarazi ashyirwa igabanyijemo ibice bine. Abakoresha ubusanzwe bakoresha indobo nto (igiciro cy'ibikoresho) mu gihe birengagiza eshatu ziganza.

Igitekerezo kiragoye ariko kiratanga umusaruro: ibikoresho byo gushyushya si cyo giciro gikomeye. Umukozi ucuruza amashanyarazi utanga igabanyirizwa rya 10% ku giciro cyo gushyushya amashanyarazi azigama amafaranga make ugereranyije n'utanga igabanyirizwa ry'amafaranga ku kigero cya 40%. Ibikorwa remezo bya BESS ni byo byonyine bigabanya ingufu, amashanyarazi, n'ingufu za opex icyarimwe.

Aho BESS Igabanyirizwa Igiciro: Uburyo Butatu

1. Kugabanya amafaranga asabwa (inkingi ikoreshwa mu gushakisha)

EMS ihora iteganya ko aho umuriro ugeze ikanasohora batiri mu gihe cy’izamuka ry’amazi, ikagira ubunini bwa kW buri munsi y’igisenge cyafashwe. Ingaruka ziyongera kuko buri kW yogoshwe igabanya kandi igabanya igiciro cy’ubwishyu cy’ikigo gikoreshwa mu gutwara no gukwirakwiza umuriro mu biciro byinshi.

2. Gukoresha ingufu no kwiyishyurira imirasire y'izuba

Bateri imwe ikoresha ingufu nyinshi iyo ingufu zihendutse cyane - igiciro cyo mu ijoro rimwe, cyangwa igiciro cy'izuba cya saa sita iyo ahantu hari hejuru cyangwa hejuru ya PV. Ibiciro byose bya kWh biva ku giciro cyo hejuru bijya ku giciro cyo hejuru bipima ibiciro by'imisoro, ubusanzwe hagati ya 0.05–0.20 USD/kWh. Ku bateri ya 625 kWh, urwego rwa arbitrage rwonyine rushobora gutanga hagati ya 9.000–37.000 USD buri mwaka bitewe n'isoko.

3. Gusubika kuvugurura grid

Inyigo ku bijyanye n’itumanaho ry’ibikoresho ku mbuga nshya zifite ingufu nyinshi zikunze kugaragaza ko transformer ivuguruye iri hagati ya 50.000 na 200.000 by’amadolari y’Amerika hamwe n’igihe cy’amezi 12-18. BESS yizeza ko urubuga rutazigera rukuramo, urugero, 300 kW, ihindura umurongo wa kVA 1.000 mu muyoboro wa kVA 400 - akenshi ikuraho burundu kuvugurura no kugabanya igihe cy’umushinga ku gihe kirenga umwaka. Uku ni ugukanda TCO ku ruhande rw’imari, kandi akenshi ni cyo kintu gifata umwanya ku mbuga za brownfield ku byuma bitanga umuriro muke.

Ishusho ya ROI: Hub ya 480 kW ifite 625 kWh BESS

Tekereza ku kugereranya gufatika. Ahantu A ni umuhanda munini wa 480 kW gusa (chargers enye za 120 kW). Ahantu B ni ihuriro rimwe hamwe na 625 kWh [BESS integrated charger station] (https://www.midapower.com/bess-charging-station/), hamwe n'umuyoboro wa 300 kW. Zombi zitanga umuvuduko umwe: amasaha 150 ku munsi, 30 kWh interahamwe y'igihembwe.

Imibare iragaragaza ariko irakomeye mu buryo bw'icyerekezo muri Amerika no mu muryango w'ubumwe bw'ibihugu by'Uburayi: urubuga rwa BESS rugabanya opex ikoreshwa mu bijyanye n'ingufu ku kigero cya 20-30% buri mwaka, rwirinda ikiguzi cyo guhuza amashanyarazi mu buryo bw'amanota atanu, kandi rukongera kugaruza capex yarwo mu myaka igera kuri 4-6. Byose nyuma y'ibyo ni inyungu - kandi ikigo cy'itumanaho nacyo kirwanya ibura ry'amashanyarazi, ibi bikaba birinda inyungu mu gihe cy'ibikorwa by'amashanyarazi byahagarika umunywanyi wa grid gusa.

Ibiciro by'imikorere byangiza inyungu mu buryo bucece

Igiciro cyo kugura ni cyo gishotora; opex ni umutego. Ibyemezo bitanu by'imikorere bigena niba urubuga rwa BESS rugera ku bwishyu bwarwo bwagenwe:

1. Gucunga ubushyuhe.Bateri za Lithium ziragabanuka hejuru ya 35°C no munsi ya 0°C. Sisitemu zikonjeshejwe n'amazi zigumana ingufu zigenwe mu kirere cya 50°C; sisitemu zikonjeshejwe n'umwuka zitakaza umusaruro wa 10–25% mu mpeshyi - neza neza iyo amafaranga asabwa ari menshi cyane. Garagaza [modules z'amashanyarazi zikonjeshejwe n'amazi] (https://www.midapower.com/liquid-cooled-power-module/) n'imicungire y'ubushyuhe bwa batiri ijyanye n'ikirere cyawe. 2.Inyigisho zo gutwara batiri.Buri ruziga rwuzuye rungana rukoresha agace gato k'ubuzima bwa bateri. EMS igomba kugabanya uburebure bw'amazi asohoka kugeza ku rwego rw'icyitegererezo cy'imari (ubusanzwe 80–90% by'abakoresha amashanyarazi, amagare arenga 6.000). Imyitwarire y'abarinda ni amafaranga y'ubuntu. 3.Amafaranga ya porogaramu n'imicungire.Imbuga z’ubuyobozi zikurikiza amategeko ya OCPP zishyuza kuri buri shajara buri kwezi. Hitamo mbuga zihuza BESS, shajara, na metering mu gice kimwe - gucikamo ibice by’urubuga byongera bucece hagati ya 100 na 500 USD kuri buri muyoboro ku mwaka. 4.Kubungabunga umutekano ugereranije no kubungabunga ibyangiritse.Imiyoboro yo gukonjesha amazi, contactors, na relay zo kurinda umuriro bisaba serivisi iteganyijwe. Guhagarara rimwe gusa ku gice cy'amashanyarazi cya 480 kW bishobora gutwara amafaranga arenze amasezerano y'umwaka yo kubungabunga mu mafaranga y'inyongera yatakaye n'amafaranga y'ibihano by'imisoro. 5.Guhuza garanti.Garanti za batiri zitangwa mu byiciro cyangwa mu myaka, icyo ari cyo cyose kiza mbere. Huza igihe cy'ingwate n'ingengo y'imari ya arbitrage/peak-shaving cycle, bitabaye ibyo batiri izasaza imyaka myinshi mbere yuko charger ibikora.

Amahitamo yo gutanga amasoko n'igishushanyo mbonera arengera inyungu

Ibyemezo byongera inyungu ikomoka ku nyungu bifatwa mbere y'uko itegeko ryo kugura ritangira, ntabwo ari nyuma ya:
