Technology development provides new opportunities to drive the innovation and the the design of wind farms. CNets spin-off company CheckWatt implements direct frequency regulation for wind power and to enable the integration with battery storage and the option capacity to produce hydrogen.
The SVEF (Sveriges Vindkraftkooperativ Ekonomisk Förening – Swedish Windpower Cooperative Economic Association) has designed an installation to be build north of Ulricehamn.
In the first step three wind turbines from Enercon will be connected to the grid frequency through the new support service FCR-D down, which Svenska Kraftnät introduced on 1st January 2022. This service enables the plants to reduce production within a few seconds if the frequency exceeds the Nordic synchronous range of 50.1 Hz. For owners of wind power this option can generate significant revenue as well as it enables the electrical system to directly utilize a more versatile production environment which enables a more stable operation in general.
CheckWatt enables a 100% renewable energy system through measurement, analysis, visualization and control. CheckWatt’s services offer the following components:
- Currently – a virtual power plant built from aggregated resources with CheckWatts EMS that supports the frequency of the electricity network and relieves bottlenecks in local networks.
- IMD – an individual measurement and charging for electricity, water and electric car charging with unique integration to solar power plants and energy storage.
- EnergyInBalance – a Platform with operational monitoring and visualization for resources with CheckWatt EMS and IMD systems. Also integrated in products of cooperation partners.
