Research on Topology and Control Strategy of Energy Router Based on Multi-station Integration System

With the further development of distributed renewable power generation, its randomness and volatility greatly affect the renewable energy consumption and the safe and stable operation of the grid. To address this problem, researchers have proposed the concept of energy Internet to enhance the control and scheduling capability of the power grid through power electronics technology, so as to solve the challenges brought by renewable energy generation to the power grid. Energy routers, as the core equipment of the energy Internet, have received extensive attention in recent years. This paper introduces the typical topology of energy router based on the three-stage structure of input stage, isolation stage and output stage, and briefly describes the control strategy corresponding to the three-stage structure. The coordinated control strategy of the energy router is proposed in this paper and the effect of the control strategy is verified based on the simulation result of multi-station integration system.
