Expanding networks quickly and cost-effectively<\/h2>\n
The high\u00ader the share of renew\u00adable ener\u00adgies fed into the grid, the high\u00ader the degree of nec\u00ades\u00adsary grid expan\u00adsion. This is because with a lot of wind and solar pow\u00ader, volt\u00adage fluc\u00adtu\u00ada\u00adtions in the dis\u00adtri\u00adb\u00adu\u00adtion net\u00adwork increase sharply.<\/p>\n
Each coun\u00adtry has dif\u00adfer\u00adent toler\u00adances for volt\u00adage fluc\u00adtu\u00ada\u00adtions. These vary from plus\/minus five to ten per\u00adcent. Guar\u00adan\u00adtee\u00ading these tol\u00ader\u00adances is becom\u00ading more dif\u00adfi\u00adcult for grid oper\u00adators as the share of renew\u00adables in\u00adcreases. The solu\u00adtion: grid expan\u00adsion. But there are two approach\u00ades to this. First, the com\u00adplex and cost-inten\u00adsive expan\u00adsion with thick\u00ader lines and more local net\u00adwork sta\u00adtions. Sec\u00adond, the more cost-effec\u00adtive, flex\u00adi\u00adble expan\u00adsion using volt\u00adage reg\u00adu\u00adla\u00adtion dis\u00adtri\u00adb\u00adu\u00adtion trans\u00adform\u00aders, so-called VRDTs. With the lat\u00adter, the final con\u00adtrol point moves from the sub\u00adsta\u00adtion to the local net\u00adwork sta\u00adtion which makes it eas\u00adi\u00ader to keep the volt\u00adage sta\u00adble, because the grid gets more inter\u00adme\u00addi\u00adate con\u00adtrol points that reg\u00adu\u00adlate close to the source. For such approach\u00ades, the ECOTAP\u00ae VPD\u00ae on-load tap-chang\u00ader can be inte\u00adgrat\u00aded into exist\u00ading trans\u00adformer designs with lit\u00adtle effort\u2014no new lines or build\u00adings are required. Replac\u00ading an exist\u00ading unreg\u00adu\u00adlat\u00aded local trans\u00adformer with a reg\u00adu\u00adlat\u00adable one takes about one day. A com\u00adplete line upgrade would take months.<\/p>\n
Increased capacities<\/h3>\n
How\u00adev\u00ader, ECOTAP\u00ae VPD\u00ae not only favors the ener\u00adgy turn\u00adaround through its increased absorp\u00adtion capac\u00adi\u00adty for renew\u00adable gen\u00ader\u00ada\u00adtors in the dis\u00adtri\u00adb\u00adu\u00adtion grid. With the tri\u00adumphant advance of elec\u00adtro\u00admo\u00adbil\u00adi\u00adty, the load-side demands on the grids will also increase mas\u00adsive\u00adly. In this case, too, grid oper\u00ada\u00adtors will ben\u00adefit from the increased absorp\u00adtion ca\u00adpacity of the grids due to the VRDT.<\/p>\n TALENT 2<\/em><\/p>\n Wind tur\u00adbine or open-space pho\u00adto\u00advolta\u00adic pow\u00ader plants require local con\u00advert\u00aders that con\u00advert DC volt\u00adage into AC volt\u00adage for grid feed\u00ading. The per\u00adfor\u00admance of a con\u00advert\u00ader is defined by the amount of max\u00adi\u00admum cur\u00adrent and the applied grid volt\u00adage. Since the volt\u00adage can fluc\u00adtu\u00adate, man\u00adu\u00adfac\u00adtur\u00aders of wind and PV sys\u00adtems must base the per\u00adfor\u00admance on a volt\u00adage val\u00adue. Usu\u00adal\u00adly, this is the nom\u00adi\u00adnal volt\u00adage val\u00adue or less\u2014but nev\u00ader the volt\u00adage opti\u00admum. This is why the appar\u00adent pow\u00ader that an invert\u00ader can pro\u00advide is large\u00adly depen\u00addent on grid fluc\u00adtu\u00ada\u00adtions. This can lead to the sit\u00adu\u00ada\u00adtion that in oper\u00ada\u00adtion the fed-in active power\u2014and only this is usu\u00adal\u00adly paid for! \u2014 is low\u00ader than what the ener\u00adgy source would pro\u00advide in the case of strong wind or strong solar radi\u00ada\u00adtion. Unwant\u00aded active pow\u00ader reduc\u00adtions can have anoth\u00ader cause such as when the grid volt\u00adage fluctu\u00adates and the reac\u00adtive pow\u00ader demand of the grid turns out to be so high that, togeth\u00ader with the active pow\u00ader pro\u00advid\u00aded, it exceeds the appar\u00adent pow\u00ader capac\u00adi\u00adty of the invert\u00ader. Until now, in such cas\u00ades one could either throt\u00adtle the valu\u00adable active pow\u00ader or pro\u00advide cost\u00adly but most\u00adly unused reserve con\u00advert\u00ader pow\u00ader and reac\u00adtive pow\u00ader sources.<\/p>\n The cheap\u00ader solu\u00adtion to get every\u00adthing out of the plants is to replace the trans\u00adform\u00aders on the invert\u00aders with reg\u00adu\u00adlat\u00aded trans\u00adform\u00aders. They reg\u00adu\u00adlate the volt\u00adage so that it is opti\u00admal for the invert\u00ader and ensure that the max\u00adi\u00admum active pow\u00ader can be fed in at every oper\u00adat\u00ading point. The result: up to ten per\u00adcent more usable pow\u00ader from wind and PV\u2014according to plan and cer\u00adti\u00adfi\u00adable. With the ECOTAP\u00ae VPD\u00ae mini on-load tap-chang\u00ader, the basic design of VRDTs can remain unchanged. This is an advan\u00adtage for wind pow\u00ader plants, for exam\u00adple, where the trans\u00adformer sits direct\u00adly in the nacelle. and vol\u00adume and weight play a cen\u00adtral role. Oth\u00ader en\u00ader\u00adgy-tran\u00adsi\u00adtion plants with con\u00advert\u00aders also ben\u00ade\u00adfit from the pow\u00ader boost pro\u00advid\u00aded by low-cost, con\u00adtrol\u00adlable trans\u00adform\u00aders: for exam\u00adple, urgent\u00adly need\u00aded bat\u00adtery stor\u00adage sys\u00adtems or elec\u00adtrolyz\u00aders for hydro\u00adgen pro\u00adduc\u00adtion.<\/p>\n![](\"https:\/\/onload.reinhausen.com\/de\/wp-content\/uploads\/sites\/25\/2022\/12\/Motor_modul.jpg\")
