Improvement of the power quality in the utility grid can be obtained by connecting damping power-electronic devices. Regarding the increased presence of converter-based distributed generation units in the power system, an active front end for distributed generation units is extended with a mitigating function. However, in order to encourage the connection of mitigating devices to the power system, damping behaviour should be financially rewarded. In this paper, the financial benefits of connecting a damping distributed generation unit to the present power system are verified.
