Indonesia is an archipelagic country with a total of 17.000 islands scattered throughout its territory. Due to the widespread presence of these islands, Indonesia also possesses a high potential for renewable energy that can be harnessed. Nevertheless, many islands still lack access to reliable electricity in rural areas. To address this issue, a DC Microgrid system is proposed in this research. Cluster topology is employed because of its ability to operate either interconnected or independently within several small building blocks. The research results show that the design of a DC Microgrid system with cluster topology for rural areas was successfully realized. The system is composed of one or more building blocks called Multisource PCS with decentralized control over each building block. Each Multisource PCS has a rated capacity of 3 kW and consists of a DC Link and DC Grid buses, power converters, battery, and solar panel. Decentralized control enables independent or connected operation of the Multisource PCS with controlled power flow capabilities within and between Multisource PCS.
