An enhanced hierarchical control strategy for the Internet of Things-based home scale microgrid

As the intelligent control and detection technology improving, more and more smart devices/sensors can be used to increase the living standard. In order to integrate the Internet of Things (IoT) with microgrid (MG), an enhanced hierarchical control strategy for IoT-based home scale MG is proposed in this paper. Physical smart devices/sensors and inverters are defined at the primary level. Electrical and environmental variables deviation restoration loops are adopted at the secondary level. Power flow management and optimization algorithms with different objectives are deployed at the tertiary level. In this sense, the IoT infrastructure can be smoothly integrated with the original MG hierarchical Control theory. The proposed structure will be implemented in an IoT MG laboratory in line with VICINITY project at Aalborg University, Denmark.
