Abstract Energy router with energy buffer will significantly facilitate performance improvement such as loss compensation, and instruction implementation of dispatching center in Energy Internet. To achieve high power density, high energy density, and high reliability, the energy buffer is implemented via a hybrid energy storage system and paralleled multiple modules. A minimum loss model of energy buffer devices is constructed to optimize the operating efficiency and energy management of multiple energy storage units. Based on the minimum loss model, a rule-based energy buffer strategy for the energy router is proposed to achieve minimum loss and energy management in real-time control. A novel power allocation method for different types of storage units is designed to better eliminate over-limit power in energy-type storage units in peak periods, thus extending their lifetime. Simulation results demonstrate the effectiveness of the proposed rule-based energy buffer strategy for energy routers in achieving highly efficient and seamless operation and energy management of energy storage units.
