The proposed scheme allows to reduce the communication cost of classical distributed control schemes, thus possibly reducing privacy and security concerns, while guaranteeing scalability properties, by adopting a leaky integral controller. Based on the droop control mechanism, the model for Alternating Current (AC) MG clusters is considered. A leader-follower-based decentralised-distributed secondary control is then designed for frequency restoration and active power sharing among and within clusters, respectively. The parameters selection for the proposed controller is also analysed and simulations show the effectiveness of the proposed decentralised-distributed control method. %C Stockholm, Sweden %B 2024 European Control Conference (ECC) %V 2024 %A Jinhui Wu %A Fanghong Guo %A Francesca Boem %T Decentralised-Distributed Secondary Frequency Restoration and Power Sharing Control for Microgrid Clusters %D 2024 %P 279-284
