Paving the Way to Smart Micro Energy Internet: Concepts, Design Principles, and Engineering Practices

internet is one of the most promising future energy infrastructures which could enhance energy efficiency and improve system operating flexibility. In analog to the micro-grid, micro energy internet puts more emphasis on distribution level and consumer side. The concept and design principles of smart micro energy internet are proposed to accommodate micro-grids, distributed poly-generation systems, energy storage facilities, and related energy distribution infrastructures. The dispatch and control system of the smart micro energy internet should be responsive to external disturbance and able to approach a satisfactory operating point which compromises multiple criteria, such as safety, economy, and environment protection. To realize the vision of the smart micro energy internet, engineering game theory based dispatch and control strategies are investigated. Based on the proposed architecture and energy management system, a prototype of the first domestic solar based smart micro energy internet is initially established in Qinghai University.
