The Design and Energy Management Strategy of an Integrated Energy Router Oriented towards Rural Areas

With the proposal of the “dual carbon goals”, China is vigorously developing a new type of power system with new energy as the main body, and the energy router, as the core of the new power system, has also attracted much attention. This paper takes the smart livable countryside as the application scenario and studies the “wind-solar-hydrogen-oxygen” integrated energy router, proposing an energy router that can comprehensively utilize photovoltaic arrays, wind turbine sets, and energy stored in batteries, and supply them to AC and DC loads, and utilize electrolyzers, expanding the application scenarios of small power level energy routers. The paper first emphasizes the importance of developing energy routers, analyzes the current state of research at home and abroad in this field, and then describes the hardware topology of energy routers, control strategies for each unit, and energy management strategies based on this, using simulation models to verify the feasibility of the suggested scheme. In the design of energy routers, the article provides a detailed account of the overall design of the energy router, including the characteristics of various energy modules and their corresponding topologies of power electronic converters. The paper further formulates an energy management strategy founded on the actual situation of daily life in the countryside, divides into six working conditions, and simulates the operation of the energy router under each working condition. The simulation results demonstrate that the and simulates the operation of the energy router under each working condition. The simulation results demonstrate that the suggested energy management strategy can cope with different working conditions and achieve optimized operation of the suggested energy management strategy can cope with different working conditions and achieve optimized operation of the energy router.
