1 visoko integriran dizajn, ki ustvarja skladiščenje energije "vsestransko skladišče"
Zabojniki za shranjevanje energije močno vključujejo jedrne komponente, kot so sistemi za baterije, sistemi za upravljanje baterij (BMS), sistemi za pretvorbo energije (PCS), sistemi toplotnega upravljanja in požarni in varnostni sistemi v standardizirane zabojnike ., ki je za vsebnost za shranjevanje energije, ki jo je zagnala, kot primer, enakovredna potrošnja, ki je enaka, ki je enaka, za enotno potrošnjo.
Glede na baterijske sisteme lahko vrste baterij, kot sta litijev železni fosfat in tritij, lahko prožno konfiguriramo v skladu z različnimi zahtevami uporabe . litijeve železove fosfatne baterije se pogosto uporabljajo v električnem omrežju in industrijske in komercialne scenarice energije zaradi visoke življenjske dobe in dolgega cikla; Ternary lithium batteries have the advantage of high energy density and are suitable for scenarios that require high space compactness. The battery management system is like the "smart brain" of an energy storage container, monitoring the voltage, current, temperature, state of charge (SOC) and other parameters of each battery cell in real time to accurately control the charging and discharging process of the battery, ensuring the consistency and safety of the battery Pack . Na primer, ko je zaznana temperatura baterije, ki je previsoka, BMS takoj aktivira sistem toplotnega upravljanja in prilagodi strategijo polnjenja in izpraznjenja, da se izognete tveganju za toplotno pobeg .
The energy conversion system is responsible for bidirectional conversion between the direct current of the battery and the alternating current of the power grid, achieving flexible storage and release of electrical energy. Its fast response capability can complete power regulation in milliseconds, meeting the needs of power grid frequency and voltage regulation. The thermal management system adopts multiple heat dissipation methods such as liquid cooling, air cooling, or phase Spremenite materiale, ki bodo sodelovali, in zagotovite, da je temperatura delovanja baterije stabilna v ustreznem območju . Sistem tekočega hlajenja določene blagovne znamke zabojnikov za shranjevanje energije lahko nadzoruje nihanje temperature znotraj vsebnika v ± 2 stopinji, kar učinkovito podaljša življenjsko dobo baterije . požar in varnostni sistem, ki je na voljo s plinskim požarom, plamenskim nadzorom, plamenskim nadzorom, plamenskim nadzorom, plamenskim nadzorom, plamenskim požarom, plamenskim nadzorom, plamenskim požarom, plamenom in plin Nenormalnost se lahko aktivira v zelo kratkem času, da zagotovite varnost osebja in opreme .
2 modularni uvajanje za prilagodljivo in učinkovito uporabo
The modular nature of energy storage containers enables rapid deployment according to project requirements. Whether it is a small distributed energy storage project or a large centralized energy storage power station, the energy storage scale can be adjusted by increasing or decreasing the number of containers. In industrial parks, enterprises can install 1-2 energy storage containers according to their own electricity load characteristics, and use the peak Razlika v ceni električne energije v dolini za zmanjšanje stroškov električne energije; V obsežnih vetrnih elektrarnah in fotovoltaičnih elektrarnah se na stotine zabojnikov za shranjevanje energije izvaja vzporedno, kar lahko učinkovito zgladi nihanja proizvodnje obnovljivih virov in izboljša sposobnost absorpcije čiste energije .
This modular deployment method greatly shortens the project construction cycle. The construction of traditional large-scale energy storage power stations takes months or even years, while using energy storage containers, from production to installation and commissioning, can be put into use in as little as a few weeks. Meanwhile, modular design also reduces the difficulty of operation and maintenance. When a container malfunctions, it lahko hitro izoliramo in zamenjamo, ne da bi to vplivalo na delovanje celotnega sistema za shranjevanje energije . Poleg tega jim standardizirana zasnova zabojnikov za shranjevanje energije omogoča hitro doseganje projektnega mesta z različnimi prevoznimi metodami, kot so morje in kopenski promet, še posebej primerni za konstrukcijo projektov za shranjevanje energije v oddaljenih območjih in posebna okolja, kot so otoki .
3 več scenarijski aplikacija, sprostitev vrednosti shranjevanja energije
Na strani omrežja lahko zabojniki za shranjevanje energije sodelujejo v pomožnih storitvah, kot so britje, regulacija frekvenc in lajšanje zastojev omrežja . v obdobjih najvišje porabe električne energije, zabojniki za shranjevanje energije se odvajajo, da dopolnijo napajalno vrzel; Charging during off peak periods, storing excess electricity, and achieving "peak shaving and valley filling". In California, multiple energy storage container projects participate in grid peak shaving, reducing investment in new thermal power units annually. In terms of frequency regulation, energy storage containers, with their fast response capability, can effectively suppress grid frequency fluctuations and ensure stabilno delovanje elektroenergetskega sistema .
Industrijski in komercialni sektor je pomemben scenarij aplikacije za zabojnike za shranjevanje energije . za velike potrošnike električne energije, kot so nakupovalni centri, pisarniške zgradbe in podatkovni centri, lahko zabojniki za shranjevanje energije uporabijo kot rezervne vire energije v primeru izpada električne energije, pri čemer se lahko porabijo razlike v energiji za energijo, ki se razlikujejo po energiji, ki se razlikujejo po energiji, ki se razlikujejo po energiji, ki se razlikujejo v energiji, ki se pojavljajo v energiji, ki se razlikujejo po energiji, ki se razlikujejo po energiji. significantly reduce electricity costs. After installing energy storage containers in a large shopping mall, it saves over one million yuan in electricity bills annually. In addition, in some industrial parks, energy storage containers can also be combined with distributed photovoltaic power generation systems to build microgrids in the park, achieving self-sufficiency and optimized utilization of energija .
In the field of renewable energy, the construction of energy storage containers in conjunction with wind farms and photovoltaic power stations can effectively solve the intermittent and fluctuating problems of renewable energy generation. In a million kilowatt wind solar energy storage integration project in Gansu, the application of energy storage containers has reduced the output fluctuation rate of wind and solar power from 30% to within 10%, significantly improving the Sposobnost mreže, da sprejme čisto energijo in zmanjša pojav vetra in omejevanja sončne energije .
