Integration of batteries in the electricity grid

Integration of batteries in the electricity grid

An increase in electrification and distributed energy resources causes increased challenges in the distribution 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
 

Typical projects for us:

  • Assessment of how battery systems can contribute to improving power quality in the distribution grid 
  • Analyses of measurement data from battery projects 
  • Load flow analyses of grids containing battery systems with different operation strategies  
  • Cost-benefit analyses of integration of battery systems in the distribution grid for both grid companies and customers
 

The methods we use:

  • Modelling and simulations
  • Laboratory experiments
  • Field measurements

Who are we doing this for?

  • Grid companies 
  • Customers with batteries 
  • Battery system suppliers
