Abstract: |
With a large number of distributed generators connected into the power system, the structure and operation mode of the traditional power system are changed. As an inevitable development trend of future grid, government and experts pay more and more attention to energy internet increasingly. Energy internet system is becoming the current hot issues. As a key interface equipment of energy internet system, energy router has two features, i.e. unified energy transmission interface and unified communication interface. This paper designs a structure of energy router based on distributed power generator resources. It is divided into core control communications part and energy transmission part. This paper carries on the comprehensive analysis and design to energy router’s power transmission part, and tries to achieve the purpose of the power supply of high efficiency, stability and energy saving by building DC and AC bus dynamic interactive. The power transmission part of the energy router is modeled and simulated. By analyzing the simulation results, the quality of the AC side and DC side of the energy router system can meet the requirements of power quality.
