Research On Energy Flow Control Based On Operating Condition Set Of Energy Router

As an important part of the energy Internet,the energy router has an indispensable position in the field of integrated energy,and its topology and operation mode are the research focus of improving energy utilization efficiency.However,the currently proposed energy router model cannot change the energy flow inside the energy router in time when dealing with complex operating conditions,and needs to manually adjust its energy flow to respond to the demand of the source network.At present,most researches on energy routers are electric energy routers.The topology and model of energy routers in multi-energy forms have not been mentioned yet.This article proposes a structure of energy routers in multi-energy forms,aiming at the complex operating conditions of energy routers,innovative The operating conditions of multi-energy energy routers are classified based on the new energy output level.The load status of the power grid,gas network and heating network is used to refine the operating conditions,and a complete set of energy router operating conditions is proposed.Aiming at the problem of unstable operating mode and slow response of energy routers,this is based on the complete set of operating conditions of energy routers proposed to control the internal energy flow of energy routers to respond to the load demand of the power grid,gas network,and heating network,and obtain the operation of the energy router The complete solution set of working conditions,and the corresponding control strategy and scheduling algorithm are proposed.In addition,because the operation mode switching of the energy router involves the start and stop of the equipment and the change of the energy flow path,the mode switching method of the energy router is studied in this article,and it is found that the process of switching the new energy grid-connected mode to the CHP grid-connected power generation mode will have an impact The current affects the stability of the power grid,and a smooth control strategy based on repeated control of mode switching is proposed to reduce the inrush current.Finally,actual data is used to verify the effectiveness of the energy flow control method proposed in this paper based on the operating conditions of the energy router.
