Current distribution network 2.0: networks no “showstopper” for energy transition and e-mobilitat

Power distribution network 2.0: Networks no'showstopper' fur energiewende und e-mobilitat'showstopper' fur energiewende und e-mobilitat

Michael Lehmann, Head of Process and System Management at the Saxony-Anhaltische Electric Company with network, considers the controversial intelligent electricity benefits as an unasked for energy and roads. "We have to attack smart meters at the e-mobilitat to build a secure communication interface between customers and network operators", He explained at a specialist in the Grununa parliamentary group to the power distribution network 2.0.

UNIGIG is an extended legal frame to e-vehicles "Intelligent over Smart Meter" Include to the existing distribution network structures. Neither is Dafur "a gateway" like a kind of fritzbox, in which everything is already wired. To take care of the interface "do not make sure that you can not use any more". The cost of such a device was not allowed to exceed 80 to 100 euros.

Exercised requirements

Against smart meters there are data protection concerns, critics speak of "Spy numbers", Since the usage behavior of consumers is comprehensible. The implementation of the technology intended by the Bundestag 2016 "dragging", Rooms Fabian Joas, Head of Political Relations at the Volkswagen e-Mobilitandess Elli,. The initiative is "supervised with crazy requirements", which could ultimately bring little: "We build forward Front Knox, in the back there is an e-stove that comes from China and not so high safety standards." This is where the ture for hackers is far open.

In the debate on E-Mobile and the power grid focused on this country, the rope of the rider applies to the concern of the distribution system operators in front of a blackout through a significantly higher demand in stob times. In the background is the thought, "the fluctuating generation from renewable energies intelligently bring together with consumption", As the green faction vice Oliver Krischer formulated: the distribution system is the place where the energy transition and climate protection were most clearly combined with digitization.

Unexpected load tips

When a challenge is that unknowledged load tips could occur if Kunftig consumers want to load their new E cars at home in the evening. In "Strong exceptional situations" The operators expected that their lines could be overloaded, Lehmann explained. The ENVIA subsidiary therefore work on new concepts with incentives for users. It’s about that "Private bidirectional shop", in which the car also serve as local battery storage using the required interfaces and connect to the network.

For the info of the customer about a current "Strong feeding of wind and solar energy" I have developed an app that reports the current CO2 footprint of the current display, Lehmann reported by a running pilot project. The consumer can be flexible about this traffic light, "When gruner power is on the net". Temporary variable network charges or the transfer of Pramien from the gross trading are also conceivable. Previously, the consumer protection association VZBV had been pronounced together with the automotive industry for such adapted electricity prices.

The consumer will have to acquire a small energy management system for such a model, Lehmann was leaving. This "Mini-device" Worriage then "With our information from the network DAFUR", Move the loads in feed-in-paced times. So let yourself be in the "Happy Hour" Based on a red line and the display of available capacitants, everything coordinate well and everyone comes to the course. Under the line Konnne on the average driver so a year coming out a savings of around 150 euros. Overall, the additional customers received the prices for all perspective: "Everything has its righteousness."

Distribution networks No bottleneck for the energy transition

The needed technology for such charging approaches "is not there yet", Stressed Joas. Only innovative providers among the approximately 900 distribution network operators in this country are already pretended. Nevertheless, there is no time prere, one "uneasant" as a change. Currently, it emanates to strain, where demand could be particularly roughly "Local station transformer" to replace. However, in many customers, Paragraph 14a Energy Energy Law, however, rushed: This giving network operators the right to interrupt a charging process up to two hours a day.

Today, the even punished for bidirectional charges, Arndt Borkey gave new energy economy (BNE) from the Federal Association. Because only with coarse stucco numbers you can also make the technique behind it. Required is therefore a clear line, so customers "with market-proof behavior" saved some money. Partly there are it with these and at carmuners but also the fear, "that the batteries suffer below".

At least for the distribution networks itself, Fanny thousandtheufel, project manager industrial policy at Agora road turn, all-clearing: This "Will not be the bottleneck for ambitious climate protection in traffic", Get out of a study of the thinking industry. Controlled charging reduce the load by up to 50 percent. The quintum investment requirements for the operators also moved "on a similar level as before". Your Resumee: "The network integration is creation, it does not cost much and will not be the show stopper for the E-Mobilitat." Furs bottleneck management would be ideal for praventive approaches like variable network charges "curative" bring together in the form of short-term loading shutdowns.
