要約(英語): In this paper, a control algorithm was proposed that is able to balance the SoCs of multiple VSGs with different capacities and droop coefficients. The rate of (dis)charge of all VSGs can be kept uniform when the SoCs are equal which will prolong the service life of the ESSs. Additionally, balancing the SoCs has the advantage that the FCR provided by the VSGs are increased compared to traditional VSG control.
