Software for virtual power plants powered by residential solar-plus-storage
With its sonnenVPP, German battery company Sonnen wants to improve the efficiency of virtual power plants which it says can offer primary balancing energy from houses with solar and storage and can operate up to 90% more cost-effectively.
With a virtual power plant (VPP) aggregated from household solar-plus-storage installations operating in Germany's primary balancing energy market since November 2018, German energy storage specialist Sonnen has developed software it says can operate the system up to 90% more cost-effectively.
The SonnenVPP package connects residential batteries and appliances to the VPP via an internet connection for only a fractional additional cost, according to the company.
Recent changes to IT requirements for Germany's four electricity transmission system operators mean even small, 25 kW systems – such as household batteries, heat pumps and electric vehicle charging stations – can be connected to the Sonnen VPP via a VPN internet connection and without any additional devices. The system, said Sonnen, means the energy provided by the VPP "can be provided in a permanently stable and significantly more economical way."
