Review and Comparative Study of Energy Routing Algorithms for Energy Internet

The Energy Internet (EI) is recently proposed as a new energy system framework for future smart grid where all distributed electrical devices are interconnected via energy routers (ERs). With the novel EI, the traditional unidirectional power supply is transformed into a multi-source networked supply, which generates the problem of energy routing. Although various methods for energy routing have been proposed, a comparison of the existing energy routing algorithms is not existent and is necessary to facilitate future research. In this paper, energy routing algorithms in EI are discussed and classified based on the application scenario and the way of power transmission. Finally, several classical energy routing algorithms are selected for detailed comparison by extensive simulations.
