Challenge and objective

  • Perform a techno-economic assessment of a Battery energy storage system (BESS) installation (A1) in a radial LV grid to maintain the voltage level within mandatory limits, and compare the results to traditional grid reinforcements (A0).

Work performed

  • Developed a simulation model in Python consisting of a model for running the battery as efficient as possible, a power flow solution model based on the backward/forward sweep algorithm, and an economic assessment.

Significant results

  • The battery is able to maintain the voltage level above the limit of 0.9 pu (A1 in figure) for all hours.
  • The cost of installing the battery is 77 % higher than the corresponding line costs, resulting in a break-even cost of the BESS of 3900 NOK/kW and 1160 NOK/ kWh for power and energy capacity, respectively.

Impact for distribution system innovation

  • Investigate the potential for using batteries for system support as alternative to traditional grid reinforcement.
