The goal is to stabilize the grid frequency. With the increasing number and complexity of both producers and consumers, the control of grid stability is more important than ever before. By implementing a load management system into the grid, various producers and consumers, such as intelligent EVs, can automatically be down — or upregulated depending on the relationship between demand and supply at the given time.
In the case of storage and bidirectional EVs, energy flows can also be reversed. Not only does the load management enhance the stability of the grid, but it also increases the rate at which renewable energy produced on-site can be consumed directly. When the demand is low, solar electricity is directed to the EVs and storage. In turn, when the demand is high, the stored solar energy can be retrieved and directed to other consumers. The combination of load management with storage and smart EVs has additional potential to reduce load peaks and further save costs.
Use of bi-directional charging stations, electrical battery storage systems and solar PV cells in conjunction with a load management system to stabilise the grid and increase the rate at which decentralised renewable energy producers can be used directly on site.
At the Baumwollspinnerei site, the smart EVs are used by citizens who work on the site. The direct use of on-site-produced decentralised energy allows for a low electricity rate. Solar power produced and used on-site is generally cheaper than buying electricity from the public grid.
