Energy, smartly distributed

The Light + Building Autumn Edition trade fair takes place in Frankfurt from October 2 to 6, 2022. The key themes include the questions of how the power supply can be optimized by means of smart grids and what steps are required in order to provide charging management of electric vehicles nationwide.

How can renewable energy be made available at all times via an intelligent power grid? To what extent does the localized management of “smart grids” prevent overloading of the infrastructure and save energy? And what needs to be changed in the expansion of existing charging infrastructure to ensure it can contribute optimally to the energy transition? The Light + Building Autumn Edition 2022 in Frankfurt holds from October 2 to 6, 2022, and provides a long-awaited platform for discussing these and other pressing questions in the industry with everyone involved. After the break forced on it by the pandemic, the special edition of the world’s leading trade fair for light and building technology offers exciting insights into the promotion of sustainable energy generation and the status quo on the road towards electrified and digital infrastructure. The “smart grid” consists of millions of electricity feed-in points and millions of electricity consumers. The digital networking of buildings, energy suppliers, and on-site consumption analysis makes it possible to know how much power is needed by whom and when. Only by means of a smart grid can energy from renewable sources be successfully fed into the grid on a large scale, for example by companies that are equipped with photovoltaic systems. The electricity can then flow in two directions and the balance of use, feed-in, and storage is optimally regulated around the clock. In this way, the power supply can itself be ensured where resources fluctuate, without the costs for this increasing disproportionately.

“The backbone of the energy transition is sector coupling. For this to work, we need to electrify and digitize buildings as well as transport,” says Klaus Jung, Managing Director of the Electrical Installation Systems Association of the German Electrical and Digital Manufacturers’ Association (ZVEI e.V.). He believes that intelligent building automation would permit substantial savings in energy requirements and CO2 emissions. With electric vehicles too, a two-way flow of electricity is conceivable in the context of the smart grid – by means of bidirectional batteries in the building or the car. For the system to function, however, there needs to be faster expansion of the current charging infrastructure so that there are always enough charging points available. “The key factor here is proximity to the home, since that’s where a large proportion of charging takes place,” says Jung, adding: “Only if bigger housing units are incorporated can there be bright prospects for the future vision of the e-vehicle as a storage facility for locally produced regenerative energy.” The basis for this development is a precise needs analysis of the type and number of vehicles that will use the site for charging. Just as important, Klaus Jung believes, is the charging power of the vehicles, the expected parking duration, and the general charging behavior. This overview could permit comprehensive performance management and optimal control over the charging processes.

In addition to the exciting insights relating to the topics of networking, automation, and regenerative energies, the Light + Building Autumn Edition offers a technology forum for interdisciplinary exchange in cooperation with the ZVEI. In the run-up to the event, it will also be possible to get in touch with the business partners you are looking for via the Light + Building Digital Extension from October 2 to 14, 2022.
