Grid-Forming vs Grid-Bihainim BESS: Yu Mas Yusim Wanem?

Sapos yu makim namel long wanpela grid-foming na grid-bihainim bateri eneji stoa sistem em i no samting bilong makim "moa advans" inveta mod. Tupela rot i save mekim ol narapela narapela wok bilong pawa, na stretpela rot bilong makim i dipen long strong bilong netwok, ol rot bilong wok we ol i nidim long bateri plent, ol rul bilong intakoneksen, na pefomens we ful plent i mas soim.

A grid-bihainim (GFL) BESS i wok wantaim wanpela grid voltej na frikwensi refrens we i stap pinis. A grid-forming (GFM) BESS i save holim wanpela intanel voltej na frikwensi refrens na i save wok wantaim sistem i stap klostu long dispela refrens.

Dispela samting i wok long kamap bikpela samting taim ol grid i putim bikpela namba bilong inveta-jeneresen na stoa. Tasol planti taim ol i save mekim i kamap isi tumas. Grid foming i no min olsem 'black start', 'unlimited fault current', liklik 'short-circuit-ratio limits, o gutpela ekonomiks long olgeta projek. Olsem tasol, grid bihainim i stap gut yet long planti strongpela-grid komesel, indastriel, na yutiliti aplikesen.

Grid-Forming vs Grid-Bihainim BESS long wanpela lukluk

Olsem na gutpela askim bilong statim em i no "Wanem teknoloji i gutpela moa?" tasol"Wea inveta i save kisim lektrikel refrens bilong en, na wanem samting plent i mas mekim taim dispela refrens i no strong o i lus?"

Wanem Em Grid-Bihainim BESS?

Wanpela grid-bihainim BESS i yusimsistem bilong senisim pawa (PCS)long mekim wok wantaim wanpela AC wevfom we i stap pinis long hap bilong koneksen.

Wanpela konvensenel GFL kontrola i save yusim wanpela 'phase-locked loop', o PLL, long skelim 'grid phase angle' na 'frequency'. Kontrola i save bosim 'inverter current' bilong givim 'active' na 'reactive' pawa we ol i nidim.

Long tingting, 'sequence' em:

1. Grid o narapela voltej-foming sos i kamapim AC wevfom.
2. Inveta i save skelim 'waveform'.
3. Kontrola i save skelim 'current' we i nidim long inapim 'power command'.
4. PCS i save putim o kisim pawa taim em i stap wankain wantaim ekstenel refrens.

Dispela 'architecture' em i gutpela na i wok gut taim grid i givim wanpela gutpela 'voltage refrens'. Ol samting we ol i save yusim em olsem 'energy arbitrage', 'peak shaving', 'demand management', 'renewable-energy shifting', 'capacity services', na planti kain 'frequency regulation'.

Bikpela hevi i save kamap taim 'voltage refrens' i no strong, i gat bikpela senis, o i lus. Wanpela GFL inveta i no inap long givim pawa long wanpela AC bas we i dai pinis bikos i no gat wanpela 'waveform' we em i ken bihainim.

Wanem samting em i wanpela Grid-Foming BESS?

Wanpela grid- we i kamapim BESS i yusim narapela kain kontrol filosofi. PCS i save lukautim wanpela 'internal voltage phasor' na i save bosim wok bung bilong en wantaim netwok long dispela refrens. Long wanpela level we i isi, em i save wok olsem wanpela 'voltage source' we i stap baksait long wanpela 'impedance'.

Dispela luksave em i bikpela samting: "GFM inap" long PCS datasit i no soim olsem BESS inap long mekim olgeta sevis we i go wantaim GFM-.

Ol komesal implementesen i ken yusim droop-bes kontrol, 'virtual synchronous machine' o 'virtual synchronous generator concepts', 'power-synchronization approaches, o ol narapela 'algorithm'. Ol dispela kontrol famili i no ken kamap olsem ol i ken senisim. Pasin bilong ol i ken senis tru long taim bilong wik-grid operesen, bikpela hevi, 'current limiting', na senis namel long grid-konekted na ailan stet.

Wanem samting Grid-Forming i ken givim

I dipen long inveta na plent disain, GFM operesen i ken sapotim:

• voltage-source behavior;

Dispela seperesen namel long inveta inap na plent-level inap em i wanpela bikpela samting long BESS prokiumen.

Hau long makim namel long Grid-Forming na Grid-Bihainim BESS

Step 1: Sekim Grid Kod na Interkoneksen Proses

Stat wantaim ol samting yu mas mekim long taim bilong koneksen. Painimaut sapos TSO, ISO, RTO, DSO, yutiliti, o netwok sevis provaida i nidim spesifik voltej-sos pasin, GFM kontrol, EMT model, wik-grid pefomens, karent-injeksen pasin, inersia, o evidens bilong komisin.

Noken kopim wanpela rikwaemen bilong Ostrelia, MISO, o Yurop i go insait long narapela maket sapos yu no sekim ol lo bilong ples.

Step 2: Tok klia long ol rot bilong wok

Askim wanem samting BESS i mas mekim:

• wok tasol taim yu konektim long wanpela helti grid;
• sapotim wanpela fasiliti taim yutiliti i pinis;
• kamapim na lukautim wanpela ailan;

• senis namel long grid-konekted na ailan mod;
• stretim gen wantaim 'utility network';
• sapotim wok bilong stretim ol narapela jeneresen o lod.

Wanpela strongpela-grid pik-seving projek na wanpela rimot maining maikrogrid i ken yusim wankain bateri hatwea tasol i nidim ol narapela narapela kontrol akiteksa.

Step 3: Skelim strong bilong sistem

Skelim SCR wantaim netwok impedens, foul level, ol IBR klostu, minimam sinkron-jeneresen kondisen, plen senis long netwok, na ol opereting senario we i kamapim grid we i no strong tumas.

Sapos i gat wari long strong bilong sistem, askim OEM na pawa-sistem konsalten long soim gutpela wok yusim ol model we i stret long stadi bilong koneksen.

Step 4: Makim Grid-Sapot Sevis

Tok klia long wanem kain pefomens i mas kamap, olsem voltej sapot, frikwensi rispons, sintetik inersia, 'oscillation damping', 'ride-through', 'island operation', 'restoration', o 'contribution' bilong strong bilong sistem.

Long ol GFM projek, ol stadi i mas soim ol 'realistic current limits' na 'mode transitions' na i no ken soim 'converter' olsem wanpela 'unlimited ideal voltage source'.

Step 7: Skelim Komesel Veliu

Skelim kos bilong GFM wok we yu nidim wantaim veliu em i kamapim. Dispela i ken inkludim ol sistem-strongpela ikwipmen we ol i abrusim, ol koneksen i kamap gutpela moa, ol sevis bilong stebiliti i kisim kontrak, ol i daunim hevi bilong stretim ol samting long bihain taim, o blak-stat na resiliens veliu.
