Abstract
The possibility to adjust the reactive power at the point of connection of battery systems will enhance flexibility provision in future renewable-based grids. Therefore, Grid Codes require verification of the reactive power capability of battery systems, which can be exploited by system operators. This paper proposes standardized testing procedures to verify reactive power functions for Grid Code compliance of battery systems. The investigated control functions are (i) reactive power control, (ii) power factor control, and (iii) automatic power factor control. The designed procedures detect the reactive power capability of battery systems thoroughly, and they verify the battery system against Grid Code compliance following three success criteria: accuracy, sensitivity, response time. The experimental testbed allows to validate a 33.5 kW / 95 kWh battery system following the requirements in the Danish Grid Code. Results show that the battery system follows the Grid Code, satisfying both reactive power capability requirements and success criteria.
