Research on communication model of DC micro-grid intelligent electricity consumption

A micro-grid is a group of interconnected loads and energy resources, which can operate in grid connected or island mode. Without frequency control, DC micro-grid makes networking operation easier. A unified communications network is needed to establish for safe and efficient operation of distributed power generation, energy storage devices and the load equipment in the DC micro-grid. By using a communications network, device control, information collection, remote management and intelligent power management can be achieved. Taking A DC micro-grid small PV generation for example, from the point of DC micro-grid energy efficiency management, communication model was studied to optimize communication resources.
