Tshooj 1: Kev Taw Qhia Txog Kev Them Nqi EV Ntse thiab Qhov Yuav Tsum Tau Ua Dynamic Load Balancing (DLB)

Kev hloov pauv thoob ntiaj teb mus rau kev siv hluav taws xob tsis yog ib qho kev hloov pauv sab nraud lawm tab sis yog lub hauv paus tseem ceeb ntawm kev tshem tawm ntawm kev thauj mus los. Thaum ntau lab lub tsheb siv lub cav sib xyaw sab hauv (ICE) raug hloov los ntawm Cov Tsheb Hluav Taws Xob (EVs), qhov kev xav tau hluav taws xob tab tom hloov ntawm cov roj kua mus rau lub network hluav taws xob. Qhov kev hloov pauv paradigm no ua rau muaj kev cov nyom loj heev rau cov khoom siv hluav taws xob uas, feem ntau, tau tsim los ntau xyoo dhau los. Qhov xwm txheej tsis tu ncua thiab muaj zog ntawm EV charging tuaj yeem ua rau muaj kev sib tsoo ntawm lub network, kev puas tsuaj ntawm transformer, thiab thaum kawg, kev puas tsuaj loj heev yog tias tsis tswj hwm nrog kev ua tib zoo.

Kev them nqi hluav taws xob ntse yog tus choj thev naus laus zis ntawm kev xav tau kev txav mus los thiab kev txwv ntawm lub zog fais fab. Hauv nws lub hauv paus, kev them nqi hluav taws xob ntse yog hais txog kev txawj ntse - paub thaum twg, ntawm qhov ceev twg, thiab nrog qhov tseem ceeb twg lub tsheb hluav taws xob yuav tsum tau them. Txawm li cas los xij, qhov tseem ceeb tshaj plaws hauv txheej kev txawj ntse no yog Dynamic Load Balancing (DLB).

Dynamic Load Balancing yog tus txheej txheem ntawm kev saib xyuas tas li ntawm lub peev xwm hluav taws xob muaj nyob ntawm ib qho chaw thiab faib lub zog ntawd rau cov EV chargers uas ua haujlwm hauv lub sijhawm tiag tiag. Yog tsis muaj DLB, lub tsev lossis chaw them hluav taws xob yuav raug yuam kom ua haujlwm ntawm qhov txwv tsis pub dhau, feem ntau yog los ntawm "qhov xwm txheej phem tshaj plaws" ntawm qhov siab tshaj plaws. Qhov no ua rau muaj kev tsis ua haujlwm loj heev: yog tias qhov chaw tsis muaj khoom siv txaus, ua rau cov neeg siv them qeeb, lossis qhov chaw xav tau kev hloov kho vaj tse kim heev los daws cov kev xav siab tshaj plaws uas tsuas yog tshwm sim rau ob peb teev hauv ib lub lim tiam.

Qhov tsim nyog ntawm DLB yog los ntawm peb qhov tseem ceeb tsav tsheb:

1. Kev Tiv Thaiv Cov Khoom Siv Hauv PausTiv thaiv cov hluav taws xob tseem ceeb kom tsis txhob tawg thiab tiv thaiv cov transformers kom tsis txhob kub dhau.
2. Kev Ua Haujlwm Zoo ntawm Kev Lag LuamTsis txhob muaj cov nqi them siab thiab cov nqi kim heev ntawm kev txhim kho cov vaj huam sib luag kev pabcuam lossis cov tes hauj lwm faib khoom hauv zos.
3. Kev Txaus Siab ntawm Tus Neeg Siv: Ua kom qhov ceev ntawm kev them fais fab rau txhua tus neeg siv los ntawm kev siv txhua kilowatt-teev uas muaj peev xwm siv tau zoo.

Hauv kev tshawb nrhiav tob tob no, peb yuav tshuaj xyuas cov txheej txheem ntawm DLB, los ntawm cov voj voog tswj hwm millisecond uas tswj hwm cov khoom siv hluav taws xob mus rau kev sib koom ua ke ntawm ntau txhiab lub chaw them hluav taws xob hauv huab. Peb yuav tshuaj xyuas seb DLB hloov pauv li cas thaum koom ua ke nrog cov chaw siv hluav taws xob rov ua dua tshiab xws li Photovoltaics (PV) thiab Battery Energy Storage Systems (BESS), thiab yuav ua li cas kev kwv yees qauv tso cai rau cov chaw them hluav taws xob loj kom kwv yees qhov kev hloov pauv ntawm lub grid ua ntej lawv tshwm sim. Thaum peb txav mus rau yav tom ntej uas EV tsis yog tus neeg siv khoom xwb tab sis yog cov peev txheej hluav taws xob faib tawm, kev nkag siab txog qhov sib txawv ntawm DLB yog qhov tseem ceeb rau cov engineers, cov neeg npaj nroog, thiab cov neeg muab hluav taws xob ib yam.

Tshooj 2: Cov Ntsiab Cai Tseem Ceeb ntawm Dynamic Load Balancing

Yuav kom nkag siab txog DLB ua haujlwm li cas, ib tug yuav tsum xub nkag siab txog lwm txoj hauv kev "Static". Hauv qhov chaw sib npaug ntawm qhov hnyav, txhua lub charger tau muab cov nqi tam sim no. Piv txwv li, yog tias ib lub tsev muaj qhov txwv 100A thiab 5 lub charger, txhua lub yuav raug txwv ntawm 20A. Yog tias tsuas yog ib lub tsheb them, nws tseem tsuas tau txais 20A, pov tseg 80A ntawm lub peev xwm muaj. Ntawm qhov tod tes, yog tias tag nrho 5 lub tsheb them thiab ib tug neeg qhib lub tshuab HVAC muaj zog hauv lub tsev, tag nrho cov khoom thauj yuav tshaj 100A, ua rau tsaus ntuj.

DLB hloov qhov kev faib nyiaj ruaj khov no nrog lub kaw lus uas ua haujlwm tau zoo thiab teb tau sai. Lub hauv paus ntsiab lus yog lub voj voog rov qab ntawm "Tag Nrho Lub Peev Xwm Muaj" thiab "Kev Xav Tau Kev Them Nqi Nquag."

Lub Hauv Paus Kev Kawm Txog Lej

Thaum nws yooj yim tshaj plaws, DLB tuaj yeem qhia los ntawm cov qauv hauv qab no:P_muaj_rau_EVs(t) = P_total_limit – P_non_EV_loads(t)

Qhov twg:

• P_total_limityog qhov txwv ntawm lub cev lossis daim ntawv cog lus ntawm qhov chaw.
• P_tsis yog_EV_loads(t)yog qhov kev siv teeb, tshuab, elevators, thiab lwm yam hauv lub sijhawm tiag tiag, ntsuas los ntawm lub 'meter' ntse.
• P_muaj_rau_EVs(t)yog lub zog seem uas tuaj yeem faib tau zoo ntawm cov EVs.

Qhov nyuaj tshwm sim thaum lub kaw lus yuav tsum txiav txim siab yuav faib li casP_muaj_rau_EVs(t)ntawm covNcov chargers. Qhov kev faib tawm no yog tswj hwm los ntawm cov algorithms uas xav txog:

• Xeev Lub Nqi (SoC)Lub tsheb uas yuav luag tsis muaj roj teeb yuav tau txais qhov tseem ceeb dua.
• Lub Sijhawm Tawm MusLub tsheb uas nyob ib hmos tuaj yeem them qeeb qeeb, thaum lub tsheb uas xav tau kev ntxiv roj sai sai yuav tau txais kev txhawb zog.
• Kev Sib Npaug TheemHauv cov kab ke peb-theem, DLB yuav tsum xyuas kom meej tias tsis muaj ib theem twg raug overloaded, ib txoj haujlwm uas xav tau kev hloov pauv logic lossis kev faib tawm theem-paub.

Kev Ntsuas thiab Kev Ntsuas

Qhov tseeb ntawm DLB yog nyob ntawm qhov zoo ntawm cov ntaub ntawv uas nws tau txais. Qhov no feem ntau cuam tshuam nrog Current Transformers (CTs) lossis cov ntsuas ntse tshwj xeeb uas tau teeb tsa ntawm qhov chaw sib koom ua ke (PCC). Cov khoom siv no yuav tsum tshaj tawm cov ntaub ntawv thauj khoom nrog zaus siab (feem ntau yog 1Hz lossis siab dua) kom tus maub los tswj DLB teb rau qhov nce siab sai sai hauv lub tsev thauj khoom - xws li lub cev muaj zog hauv kev lag luam pib - hauv ob peb feeb kom tiv thaiv lub tshuab hluav taws xob tseem ceeb los ntawm kev tripping.

Cov Qauv Hierarchical

DLB feem ntau ua haujlwm ua ib pawg neeg. Ntawm theem "Local", tus maub los tswj hwm ib pawg ntawm cov chargers. Ntawm theem "Site", nws sib koom tes nrog lub tsev tswj hwm lub tsev. Ntawm theem "Grid", nws yuav teb rau cov teeb liab Demand Response (DR) los ntawm lub tuam txhab hluav taws xob. Txoj hauv kev ntau txheej no ua kom ntseeg tau tias kev nyab xeeb hauv zos tau tswj hwm thaum tseem koom nrog hauv kev lag luam hluav taws xob dav dua.

Tshooj 3: Kev Tsim Qauv Tswj rau DLB Algorithms: PID thiab Qauv Kev Tswj Xyuas Ua Ntej (MPC)

Qhov ua tau zoo ntawm Dynamic Load Balancing system thaum kawg yog ntsuas los ntawm nws lub latency thiab qhov tseeb. Yog tias lub tsev load nce siab thiab DLB system siv sijhawm 30 vib nas this los kho qhov tam sim no ntawm EV, lub breaker tseem ceeb yuav tawg ua ntej qhov kev kho tshwm sim. Yog li ntawd, qhov kev tsim ntawm lub voj voog tswj yog "lub hlwb" ntawm lub chaw them hluav taws xob ntse. Hauv tshooj no, peb yuav kawm txog cov lus qhia txog kev tsim kho ntawm cov txheej txheem tswj hwm no, tsom mus rau Proportional-Integral-Derivative (PID) controllers thiab Model Predictive Control (MPC) uas siab dua.

Lub PID Control Framework hauv DLB

Cov tswj hwm PID yog cov neeg ua haujlwm ntawm kev siv tshuab hauv kev lag luam, thiab lawv pom ib daim ntawv thov ntuj hauv DLB. Lub hom phiaj ntawm PID voj voog yog kom tswj tau tag nrho qhov chaw thauj khoom ($P_{total}$) ntawm lossis qis dua qhov chaw teeb tsa ($P_{limit}$) los ntawm kev kho qhov hloov pauv tswj, uas yog qhov txwv tam sim no siab tshaj plaws xa mus rau EVSEs (Cov Khoom Siv Fais Fab Tsheb).

• Kev Sib Piv (P): Lub sij hawm P muab cov lus teb tam sim ntawd rau qhov yuam kev (qhov sib txawv ntawm $P_{limit}$ thiab $P_{total}$). Yog tias qhov yuam kev loj heev (piv txwv li, kev poob qis ntawm lub tsev thauj khoom), lub sij hawm P yuav ua rau lub zog them hluav taws xob EV sai sai nce. Txawm li cas los xij, kev tswj hwm P-xwb feem ntau ua rau muaj "qhov yuam kev ruaj khov" qhov twg lub kaw lus yeej tsis mus txog qhov txwv.
• Kev Sib Koom Ua Ib Ke (Kuv)Lub sij hawm I suav txog qhov kev sib sau ua ke ntawm cov qhov yuam kev yav dhau los. Nws maj mam nce qhov tam sim no kom tshem tawm qhov yuam kev ruaj khov, kom ntseeg tau tias lub kaw lus siv txhua lub ampere muaj nyob rau lub sijhawm.
• Cov Khoom Siv Derivative (D)Lub D-term kwv yees qhov yuam kev yav tom ntej los ntawm kev saib qhov nrawm ntawm kev hloov pauv. Qhov no tseem ceeb heev rau kev tiv thaiv "overshoot." Yog tias qhov thauj khoom nce sai, lub D-term yuav ua kom lub charger EV qeeb ua ntej ncav cuag qhov txwv.

Hauv ib puag ncig DLB, lub voj voog PID yuav tsum tau kho kom zoo. Yog tias nws nrawm dhau, cov EVSEs yuav hloov pauv lawv cov hluav taws xob tas li, uas tuaj yeem ua rau lub tsheb lub charger (OBC) hnav thiab ua rau EV lub software tsis zoo, ua rau muaj kev yuam kev them. Yog tias nws qeeb dhau, nws ua tsis tiav nws lub hom phiaj tseem ceeb ntawm kev tiv thaiv grid.

Tshaj PID: Kev Tswj Xyuas Qauv Ua Ntej (MPC)

Txawm hais tias PID ua haujlwm tau zoo rau cov xwm txheej yooj yim, cov chaw them hluav taws xob loj niaj hnub no siv Model Predictive Control (MPC) ntau zuj zus. Tsis zoo li PID, uas yog reactive, MPC yog proactive. Nws siv tus qauv lej ntawm lub kaw lus los kwv yees nws tus cwj pwm yav tom ntej dhau ntawm "kev kwv yees lub qab ntuj khwb."

Hauv cov ntsiab lus ntawm DLB, tus tswj hwm MPC xav txog:

2. Kev Kwv Yees Yav Tom NtejKev kwv yees qhov hnyav ntawm lub tsev raws li cov qauv keeb kwm yav dhau los, kev kwv yees huab cua (cuam tshuam rau HVAC hnyav), thiab kev kwv yees tias yuav muaj tsheb tuaj txog.
3. Lub Hom Phiaj Ua HaujlwmLub hom phiaj lej, xws li "Tso tag nrho cov nqi zog thaum xyuas kom meej tias txhua lub tsheb mus txog 80% SoC thaum 8 teev sawv ntxov."

Tus algorithm MPC daws qhov teeb meem kev ua kom zoo dua ntawm txhua kauj ruam ntawm lub sijhawm (piv txwv li, txhua 5 feeb). Nws xam cov kev ua haujlwm tswj hwm zoo tshaj plaws tab sis tsuas yog siv thawj zaug xwb, tom qab ntawd rov xam dua ntawm kauj ruam tom ntej. Qhov no tso cai rau DLB system "ua kom du" cov qauv them nqi. Piv txwv li, yog tias lub system paub tias muaj kev nce siab ntawm lub tsev loj heev thaum 2 teev tsaus ntuj, nws yuav them cov EVs ua ntej thaum 1:30 teev tsaus ntuj thiab tom qab ntawd kaw lawv kom nruj thaum 2 teev tsaus ntuj, es tsis txhob teb sai sai thaum muaj kev nce siab.

Kev ncua sijhawm thiab cov txheej txheem sib txuas lus

Lub voj voog tswj tsuas yog ceev npaum li nws qhov txuas sib txuas lus. Hauv ntau qhov teeb tsa DLB, tus maub los sib txuas lus nrog cov chargers ntawm Modbus TCP, RTU, lossis Open Charge Point Protocol (OCPP).

• Modbus: Muaj qhov latency qis heev (milliseconds), ua rau nws zoo tagnrho rau DLB hauv zos, kev nyab xeeb tseem ceeb.
• OCPP 1.6/2.0.1Tus qauv kev lag luam rau kev sib txuas lus huab-rau-charger. Txawm hais tias muaj ntau yam ntxwv (kev tswj hwm kev them nqi, kev lees paub, thiab kev hloov kho firmware), nws qhia txog qhov latency tseem ceeb (feem ntau 1-5 vib nas this) vim yog qhov overhead ntawm JSON cov lus hla WebSockets thiab kev hla ntawm lub internet pej xeem.

Cov kws ua vaj tse yuav tsum xaiv cov txheej txheem zoo raws li qhov tseem ceeb ntawm qhov sib npaug ntawm qhov hnyav. Rau lub tsev nyob, DLB uas siv huab qeeb me ntsis yuav txaus. Rau lub Hoobkas kev lag luam uas kev mus ncig ua haujlwm raug nqi ntau txhiab daus las hauv lub sijhawm tsis ua haujlwm, lub voj voog Modbus hauv zos yog qhov yuav tsum muaj.
