System energy efficiency controller, energy efficiency gain device and smart energy service system used for energy utilization

This invention describes a central controller that manages all the energy-related devices in a system, including those that generate, store, use, and even recover energy. Its job is to constantly adjust how energy, materials, and information flow between these devices to make the entire system as energy-efficient as possible. The claims narrow this to a controller for a ubiquitous energy network, specifically mentioning distributed energy systems located close to where energy is used.
