Challenge and objective

  • Batteries can be deployed at strategic locations in the grid and perform active and reactive power control for better grid utilization, as an alternative to reinforcements.
  • The lack of established computational methods for including batteries in grid planning is a barrier for taking research-based models into practice.

Work performed

  • Systematic overview of relevant methods reported in the literature.
  • Contrasting the state of the art for these research-based methods with real-world applications.

Significant results

  • CBA methods should handle investment timing as well as sizing and siting of the batteries.
  • CBA of batteries basically weights investment costs against operational benefits. The methods therefore need realistic modelling of the operational aspects of batteries: Multi-period AC, load and generation uncertainties, degradation.

Impact for distribution system innovation

  • Good CBA methods are crucial for analysing batteries and other flexible resources as alternative to traditional grid upgrade solutions.
