Decoupled, self-sufficient DC grids \u2014 how energy transition works in distribution grids<\/h3>\n\n\n\n

When peo\u00adple say ener\u00adgy tran\u00adsi\u00adtion, they often mean iso\u00adlat\u00aded grids, decou\u00adpled low-volt\u00adage, and DC grids. Because: With their grow\u00ading gen\u00ader\u00ada\u00adtion capac\u00adi\u00adties, local grids are to become increas\u00ading\u00adly inde\u00adpen\u00addent of upstream grids. Or renew\u00adables are fed direct\u00adly into the high\u00ader grid lev\u00adels with\u00adout sig\u00adnif\u00adi\u00adcant con\u00adver\u00adsion loss\u00ades.<\/p>\n\n\n\n

Con\u00advert\u00ader sys\u00adtems enable DC-AC sup\u00adply in low volt\u00adage and help to real\u00adize ener\u00adgy stor\u00adage sys\u00adtems.

Decou\u00adpling from upstream grids is essen\u00adtial for build\u00ading a com\u00admu\u00adni\u00adty ener\u00adgy sup\u00adply. GRIDCON\u00ae BESS is an ener\u00adgy stor\u00adage sys\u00adtem with pow\u00ader qual\u00adi\u00adty man\u00adage\u00adment.

DIRECT CURRENT<\/h4>
\n\t\t\t\t\t\t

DC net\u00adworks offer var\u00adi\u00adous advan\u00adtages over the clas\u00adsic sup\u00adply with AC volt\u00adage. They are more effi\u00adcient, for exam\u00adple, because one step of ener\u00adgy con\u00adver\u00adsion is omit\u00adted. The GRIDCON\u00ae DC Trans\u00adformer con\u00adverts DC volt\u00adages and offers effi\u00adcien\u00adcy, scal\u00ada\u00adbil\u00adi\u00adty and com\u00adpact design.

Volt\u00adage reg\u00adu\u00adla\u00adtion dis\u00adtri\u00adb\u00adu\u00adtion trans\u00adform\u00aders (VRDTs) can be used both to reg\u00adu\u00adlate the low-volt\u00adage net\u00adwork and to sta\u00adbi\u00adlize the medi\u00adum volt\u00adage. When more and more renew\u00adable ener\u00adgies are fed into the grid, this can lead to volt\u00adage fluc\u00adtu\u00ada\u00adtions. The ECOTAP\u00ae VPD\u00ae turns rigid dis\u00adtri\u00adb\u00adu\u00adtion trans\u00adform\u00aders into intel\u00adli\u00adgent reg\u00adu\u00adlat\u00ading trans\u00adform\u00aders.

The ener\u00adgy tran\u00adsi\u00adtion is almost inevitably more dynam\u00adic in rur\u00adal areas than in met\u00adro\u00adpol\u00adi\u00adtan areas because only there is suf\u00adfi\u00adcient space avail\u00adable to build up a sta\u00adble mix of renew\u00adable gen\u00ader\u00ada\u00adtors. In Cen\u00adtral Euro\u00adpean lat\u00adi\u00adtudes, fifty square meters of area is enough to sup\u00adply an aver\u00adage house\u00adhold with solar ener\u00adgy and new heat\u00ading tech\u00adnolo\u00adgies. How\u00adev\u00ader, the respon\u00adsi\u00adbil\u00adi\u00adty for this can\u00adnot real\u00adis\u00adti\u00adcal\u00adly lie with indi\u00advid\u00adu\u00adals. Munic\u00adi\u00adpal projects that com\u00adbine wind and solar ener\u00adgy with stor\u00adage tech\u00adnolo\u00adgies and oth\u00ader, more land-inten\u00adsive renew\u00adables can help rur\u00adal com\u00admu\u00adni\u00adties in par\u00adtic\u00adu\u00adlar move toward self-suf\u00adfi\u00adcien\u00adcy and ener\u00adgy tran\u00adsi\u00adtion.<\/strong><\/a><\/p>\n\n\n\n

Decen\u00adtral\u00adiza\u00adtion is the mag\u00adic word. Feed\u00ading solar pow\u00ader into the pub\u00adlic grid at mid\u00adday will con\u00adtin\u00adue to make no eco\u00adnom\u00adic sense in the future due to low demand and low prices. As a result, more and more house\u00adholds are already mov\u00ading toward stor\u00ading their own solar pow\u00ader and becom\u00ading increas\u00ading\u00adly inde\u00adpen\u00addent from elec\u00adtric\u00adi\u00adty sup\u00adpli\u00aders. Before this can hap\u00adpen, how\u00adev\u00ader, leg\u00adis\u00adla\u00adtures must set the reg\u00adu\u00adla\u00adto\u00adry course.<\/strong><\/a><\/p>\n\n\n\n

For com\u00admu\u00adni\u00adties and munic\u00adi\u00adpal\u00adi\u00adties, this devel\u00adop\u00adment offers even greater oppor\u00adtu\u00adni\u00adties: they can con\u00adsume their own elec\u00adtric\u00adi\u00adty in a coop\u00ader\u00ada\u00adtive while feed\u00ading sur\u00adplus\u00ades into the upstream grid. While the bat\u00adtery stor\u00adage and con\u00advert\u00ader sys\u00adtems or pow\u00ader-elec\u00adtron\u00adic grid cou\u00adplings required for decou\u00adpling or even self-suf\u00adfi\u00adcien\u00adcy are cost\u00adly for indi\u00advid\u00adual house\u00adholds, they rep\u00adre\u00adsent sen\u00adsi\u00adble invest\u00adments for munic\u00adi\u00adpal\u00adi\u00adties. They also pay for them\u00adselves quick\u00adly \u2014 not least because they allow DC grids to be imple\u00adment\u00aded and con\u00adver\u00adsion loss\u00ades to be min\u00adi\u00admized.<\/strong>\u2009<\/a><\/p>\n\n\n\n

A tech\u00adni\u00adcal alterna\u00adtive for net\u00adwork oper\u00adators to har\u00admo\u00adnize fluctuat\u00ading loads and gen\u00ader\u00ada\u00adtion between local net\u00adworks and medi\u00adum volt\u00adage are volt\u00adage reg\u00adu\u00adla\u00adtion dis\u00adtri\u00adb\u00adu\u00adtion trans\u00adform\u00aders. With these so-called VRDTs, the per\u00adfor\u00admance of the net\u00adworks can be increased with\u00adout the need for cost-inten\u00adsive line expan\u00adsion.<\/strong><\/a><\/p>\n\n\n\n

Experts agree that bat\u00adtery stor\u00adage at all grid lev\u00adels is the linch\u00adpin for the suc\u00adcess of the ener\u00adgy tran\u00adsi\u00adtion.<\/strong> <\/a>By 2030, 250 GWh of stor\u00adage capac\u00adi\u00adty will be need\u00aded for Ger\u00admany alone. This was cal\u00adcu\u00adlat\u00aded by spe\u00adcial\u00adists from Europe\u2019s largest solar re\u00adsearch insti\u00adtute, Fraun\u00adhofer ISE. As of today, Ger\u00admany only has 4 GWh.<\/p>\n\n\n\n

So there is a lot to do.
But a look behind the scenes reveals: Much of the ground\u00adwork has already been laid.<\/p>\n\n\n\n
