Abstract [en]

A method has been developed, Physical Hybrid Model, to investigate the physical large scale electrical effects of a Battery Energy Storage System (BESS) on a distribution grid by scaling the response from a small size Research Development and Demonstration (RD&D) platform. In order to realize the model the control system of an existing RD&D platform was refurbished and stability of components ensured. The Physical Hybrid Model proceeds as follows:

  1. Data from a distribution grid are collected.
  2. A BESS cycle curve is produced based on analyzed measurements.
  3. Required BESS power and capacity in investigated grid is scaled down by factor k to that of the physical test installation of the RD&D platform.
  4. The scaled BESS cycle is sent as input to control of the battery cycling of the RD&D platform.
  5. The response from the RD&D platform is scaled – up, and used in simulation of the distribution grid to find the impact of a BESS.

The model was successfully implemented on a regional distribution grid in southern Sweden.
