Integration of batteries in the electricity grid

These challenges can be lack of transfer capacity or poor power quality. In some cases, battery systems will be more cost-effective than traditional grid reinforcement. A battery system might therefore become a useful tool when grid companies are planning and operating the future distribution grid.

Costs of battery systems have fallen drastically over the last years, and prognoses indicate a that they will continue to fall. If the battery investment costs decrease sufficiently, they can become a useful tool for Norwegian grid companies. Battery systems can contribute in several ways, by for instance reducing slow and rapid voltage deviations, reducing voltage imbalance, peak shaving or as a component in a microgrid. SINTEF works with how battery systems can contribute to a more socio-economic planning and operation of the electricity grid.

We work within these areas:

• Battery systems as an alternative to traditional grid reinforcement 
• Battery systems as power support  
• The combination of battery systems and photovoltaic panels for customers 
• Battery systems in the distribution grid, microgrid and behind the meter 
• Battery systems as a flexible resource 
• Battery systems together with charging infrastructure and shore power
