Marten Bun\u00adne\u00admann is the CEO of Ava\u00adcon AG. He is con\u00advinced that VRDTs are the way for\u00adward when it comes to over\u00adcom\u00ading the chal\u00adlenges asso\u00adci\u00adat\u00aded with e\u2011mobility.<\/figcaption><\/figure>\n

E<\/span>lec\u00adtro\u00admo\u00adbil\u00adi\u00adty is on the rise all around the world. But this rais\u00ades the ques\u00adtion whether our pow\u00ader grids can cope with this trend. E.ON, Germany\u2019s largest dis\u00adtri\u00adb\u00adu\u00adtion grid oper\u00ada\u00adtor, recent\u00adly pub\u00adlished a high-pro\u00adfile study look\u00ading into the grids of its four region\u00adal grid oper\u00ada\u00adtors (Ava\u00adcon Netz, Bay\u00adern\u00adwerk Netz, E.DIS Netz, and Schleswig-Hol\u00adstein Netz). And the results con\u00adfirmed that it would be pos\u00adsi\u00adble to charge all cars elec\u00adtri\u00adcal\u00adly with\u00adin the area served by the grids by 2045.<\/p>\n

Volt\u00adage reg\u00adu\u00adla\u00adtion dis\u00adtri\u00adb\u00adu\u00adtion trans\u00adform\u00aders (VRDTs) are an impor\u00adtant part of the tech\u00adni\u00adcal infra\u00adstruc\u00adture required. Lead\u00ading the way in the use of this equip\u00adment, which was devel\u00adoped in part\u00adner\u00adship with Maschi\u00adnen\u00adfab\u00adrik Rein\u00adhausen, Helm\u00adst\u00adedt-based Ava\u00adcon Netz GmbH has a par\u00adtic\u00adu\u00adlar\u00adly impres\u00adsive reper\u00adtoire of expe\u00adri\u00adence in terms of imple\u00admen\u00adta\u00adtion and oper\u00ada\u00adtion. We talked with CEO Marten Bun\u00adne\u00admann about what the study cov\u00adered and the tech\u00adni\u00adcal solu\u00adtions<\/p>\n

Mr. Bunnemann, what do you see as the main problems when integrating electromobility into the grid?<\/h3>\n

All of our research into grid inte\u00adgra\u00adtion has revealed that the main prob\u00adlem is how dri\u00advers will go about charg\u00ading their vehi\u00adcles since we have to pre\u00addict these pat\u00adterns of behav\u00adior 15 or 20 years in advance. The key ques\u00adtions to con\u00adsid\u00ader are: How many cars will real\u00adis\u00adti\u00adcal\u00adly be charged at once and how can we make sure that the grids are able to cope with this lev\u00adel of demand? We looked into this as part of the large-scale study men\u00adtioned above, but also in many oth\u00ader stud\u00adies. We gave par\u00adtic\u00adu\u00adlar empha\u00adsis to those look\u00ading at rur\u00adal grids since our rur\u00adal spaces (vil\u00adlages and small and medi\u00adum-sized towns) have the most cars.<\/p>\n

Propo\u00adsi\u00adtion one:
\nA full switch to e\u2011mobility is a pos\u00adsi\u00adbil\u00adi\u00adty<\/strong><\/p><\/blockquote>\n

And we deter\u00admined that, on the basis of the knowl\u00adedge avail\u00adable to us now, there won\u2019t be any major prob\u00adlems for our grids if we are smart in our prepa\u00adra\u00adtions for elec\u00adtro\u00admo\u00adbil\u00adi\u00adty and stay ahead of the game. We want to be able to stand out from the crowd and not force spe\u00adcif\u00adic charg\u00ading times on our cus\u00adtomers. They should all be able to charge their vehi\u00adcles at home when\u00adev\u00ader they wish to. This is the promise we have made to our\u00adselves.<\/p>\n

To what extent do voltage regulation distribution transformers (VRDTs) feature in your plans for the upgrade work required in the future?<\/h3>\n

Trans\u00adform\u00aders and lines are known for being the main com\u00adpo\u00adnents of pow\u00ader grids. Accord\u00ading to our find\u00adings, prob\u00adlems main\u00adly occur in the trans\u00adform\u00aders and lines in the low-volt\u00adage grid, which is the part of the grid that is clos\u00adest to the cus\u00adtomers. Here, the first prob\u00adlems that almost always arise are trans\u00adform\u00aders being overload\u00aded and line volt\u00adages being too low. Any oth\u00ader issues are much less com\u00admon.<\/p>\n

What this means is that we will replace small, unreg\u00adu\u00adlat\u00aded trans\u00adform\u00aders with larg\u00ader volt\u00adage reg\u00adu\u00adla\u00adtion dis\u00adtri\u00adb\u00adu\u00adtion trans\u00adform\u00aders (VRDTs). And we will also make them intel\u00adli\u00adgent. This large\u00adly cuts out the need for line rein\u00adforce\u00adments, which often used to be required to the detri\u00adment of the gen\u00ader\u00adal pub\u00adlic.<\/p>\n

A lot of demand would be placed on the pow\u00ader grid if every\u00adone were to start charg\u00ading their cars at the same time. VRDTs help to keep the volt\u00adage con\u00adstant. (\u00a9 Timo M\u00fcller)<\/figcaption><\/figure>\n

What benefits do you expect from the use of voltage regulation distribution transformers?<\/h3>\n

To put it sim\u00adply, the use of VRDTs large\u00adly rules out volt\u00adage prob\u00adlems in the low-volt\u00adage grid, and poten\u00adtial\u00adly also the medi\u00adum-volt\u00adage grid, depend\u00ading on the spec\u00adi\u00adfi\u00adca\u00adtions. This is a very quick and effi\u00adcient way of ensur\u00ading that we don\u2019t have to sub\u00adject the gen\u00aderal pub\u00adlic to unnec\u00ades\u00adsary cable in\u00adstallation work.<\/p>\n

Propo\u00adsi\u00adtion two:
\nThere are no longer any tech\u00adni\u00adcal obsta\u00adcles stand\u00ading in the way of full e\u2011mobility.<\/strong><\/p><\/blockquote>\n

Instead, we can lim\u00adit our\u00adselves to work that is usu\u00adal\u00adly required as a result of age and to major new con\u00adnec\u00adtions that have always required grid devel\u00adop\u00adment. This is how we can fit elec\u00adtro\u00admo\u00adbil\u00adi\u00adty into the exist\u00ading grid\u2014especially when we are able to look ahead and make plans for the future.<\/p>\n

But we mustn\u2019t for\u00adget that costs are still involved. We includ\u00aded cost con\u00adsid\u00ader\u00ada\u00adtions in our study with the results show\u00ading a one-time charge of around EUR 400 on aver\u00adage per vehi\u00adcle for expand\u00ading the grid. But as far as we are con\u00adcerned, these invest\u00adments are absolute\u00adly worth\u00adwhile. It\u2019s all rel\u00ada\u00adtive, after all: Around EUR 25,000 has to be invest\u00aded in a car every sev\u00aden years on aver\u00adage.<\/p>\n

Which specific measures does the study call for?<\/h3>\n

Per\u00adhaps we should cov\u00ader one thing first of all: We are often asked why we assume that the auto\u00admo\u00adtive seg\u00adment will become ful\u00adly elec\u00adtric. We know that this is a bold assump\u00adtion but it is based on inter\u00adnal and exter\u00adnal analy\u00adses of the mobil\u00adi\u00adty sec\u00adtor, with a par\u00adtic\u00adu\u00adlar focus on sus\u00adtain\u00adabil\u00adi\u00adty and effi\u00adcien\u00adcy. The cru\u00adcial thing for us is what we now take away from the results. And we have to say that we have put togeth\u00ader an excel\u00adlent pack\u00adage.<\/p>\n

Propo\u00adsi\u00adtion three:
\nGrids can be made fit for the future with\u00adout hav\u00ading to under\u00adgo major restruc\u00adtur\u00ading.
\n<\/strong><\/p><\/blockquote>\n

What this means for our cus\u00adtomers and com\u00admu\u00adni\u00adties first off is that we will be sup\u00adport\u00ading elec\u00adtro\u00admo\u00adbil\u00adi\u00adty in every way. Instead of com\u00adplain\u00ading, we\u2019ll be moti\u00advat\u00ading because we believe this is the right direc\u00adtion to be head\u00ading in and we take the issue of CO2 very seri\u00adous\u00adly. As far as our grids are con\u00adcerned, we will be focus\u00ading on intel\u00adli\u00adgent sec\u00adondary sub\u00adsta\u00adtions with VRDTs and on larg\u00ader line cross-sec\u00adtions. But this will only be when replace\u00adments are need\u00aded, usu\u00adal\u00adly owing to age. This requires an incred\u00adi\u00adbly strate\u00adgic approach when allo\u00adcat\u00ading expan\u00adsion work but it stops us press\u00ading pause on a future issue that we don\u2019t want to aban\u00addon.<\/p>\n

The ECOTAP\u00ae VPD\u00ae is the key com\u00adpo\u00adnent in the quest to have e\u2011mobility rolled out exclu\u00adsive\u00adly. (\u00a9Timo M\u00fcller)<\/figcaption><\/figure>\n

That was sad\u00adly what many grid oper\u00ada\u00adtors did ten years ago when the first solar boom occurred before this VRDT tech\u00adnol\u00ado\u00adgy even exist\u00aded. And we don\u2019t want to be faced with an impos\u00adsi\u00adble task in ten years\u2019 time. Anoth\u00ader point worth mention\u00ading is that we will also have more solar pow\u00ader with\u00adin our grids, poten\u00adtial\u00adly includ\u00ading heat pumps, and VRDTs are ide\u00adal here. This tech\u00adnol\u00ado\u00adgy there\u00adfore helps move the ener\u00adgy tran\u00adsi\u00adtion in all direc\u00adtions.<\/p>\n

VRDTs are still quite rare around the world. What\u2019s your experience with using them?<\/h3>\n

Our oper\u00adat\u00ading expe\u00adri\u00adence has been very pos\u00adi\u00adtive. It goes with\u00adout say\u00ading that there were a few start-up and devel\u00adop\u00adment prob\u00adlems with the first series deliv\u00adered years ago. But the VRDTs we have today work in exact\u00adly the same way as stan\u00addard trans\u00adform\u00aders. But, fig\u00adu\u00adra\u00adtive\u00adly speak\u00ading, they can do twice as much!<\/p>\n

Propo\u00adsi\u00adtion four:
\nVRDT tech\u00adnol\u00ado\u00adgy is key to the ener\u00adgy rev\u00ado\u00adlu\u00adtion.<\/strong><\/p><\/blockquote>\n

And there is not even much more mate\u00adr\u00adi\u00adal required\u2014just the reg\u00adu\u00adla\u00adtor. For us this means effi\u00adcien\u00adcy, intel\u00adli\u00adgence, and sus\u00adtain\u00adabil\u00adi\u00adty. Obvi\u00adous\u00adly all of that can\u00adnot replace strat\u00ade\u00adgy and exper\u00adtise, includ\u00ading on the part of col\u00adleagues work\u00ading on the grid. But our expe\u00adri\u00adence has been so pos\u00adi\u00adtive that over 90% of our new trans\u00adformer acqui\u00adsi\u00adtions in 2019 have been VRDTs.<\/p>\n

A full switch to elec\u00adtro\u00admo\u00adbil\u00adi\u00adty rep\u00adre\u00adsents a major chal\u00adlenge for dis\u00adtri\u00adb\u00adu\u00adtion grids\u2014especially if the pow\u00ader has to come from sus\u00adtain\u00adable sources. The tech\u00adnol\u00ado\u00adgy needs to com\u00adpen\u00adsate for fluc\u00adtu\u00ada\u00adtions in medi\u00adum volt\u00adage and must be able to respond dynam\u00adi\u00adcal\u00adly to changes in feed-in and load at the low-volt\u00adage lev\u00adel. In both cas\u00ades, grid oper\u00ada\u00adtors can rely on the ECOTAP\u00ae VPD\u00ae.<\/a><\/p>\n

It com\u00adbines the exper\u00adtise that MR has accu\u00admu\u00adlat\u00aded over decades of work\u00ading with vac\u00adu\u00adum on-load tap-chang\u00aders in high-speed resis\u00adtor-type tap-chang\u00ader tech\u00adnol\u00ado\u00adgy with expe\u00adri\u00adence in volt\u00adage reg\u00adu\u00adla\u00adtion dis\u00adtri\u00adb\u00adu\u00adtion trans\u00adform\u00aders to guar\u00adan\u00adtee a sta\u00adble, main\u00adte\u00adnance-free per\u00adfor\u00admance of 500,000 tap-change oper\u00ada\u00adtions. The ECOTAP\u00ae VPD\u00ae is so com\u00adpact<\/a> that it does not make the dis\u00adtri\u00adb\u00adu\u00adtion trans\u00adformer any larg\u00ader.<\/p>\n<\/div>\n<\/div>\n
