Multi Working Condition Energy Management Strategy of Distributed Energy Internet based on Energy Router

Distributed energy is not suitable for independent self use power supply system due to its intermittent and volatile characteristics, and needs to be interconnected with other distributed power grids or public grids. Therefore, a multi working condition energy management strategy based on energy router for distributed energy Internet is proposed in this paper. According to the distributed energy Internet framework, the hierarchical control strategy is adopted to divide the control framework into three layers: distribution network layer, micro network control layer, and local control layer. Aiming at the role of each functional unit in the energy router, each port local control strategy is designed. According to the micro network control layer, the energy router is divided into six stable operating states to achieve seamless switching between multiple working conditions. Finally, the DC building energy router system simulation model is built on the Simulink simulation platform, and two typical time scenarios in a day are selected for simulation. Through the analysis of the simulation waveform, it is verified that the distributed energy Internet of the proposed energy router can realize the reasonable allocation and utilization of energy.
