Abstract: This paper proposes an energy internet with energy router as the core architecture and a multi-energy form to cope with the problem of unstable operation mode and slow response of energy router,and strive to maximize the conversion benefit of multiple energy interaction. Three operating condition sets are divided according to the output power of new energy. In order to refine the operating condition,the load state of power grid,gas network and heat network are taken as the standard to obtain the complete set of working conditions. Also,the corresponding control strategy and scheduling algorithm are put forward for precise active control of working conditions. Finally,the effectiveness of the energy flow control method based on the energy router operating condition set is verified by practical data.
