Energy Routing Algorithms for the Energy Internet

The energy internet is a new emerging concept which is mainly associated with peer to peer energy trading in a smart grid power network. To facilitate this, support for bidirectional power flow in addition to a bidirectional communication flow is needed. Thus energy routing functions/algorithms and energy routing devices are the core entities constituting the energy internet. In this paper we are mainly concerned with energy routing algorithms. These energy routing algorithms are designed based on various techniques such as graph theory, game theory and autonomous systems. Given the infancy of this area of research, in this paper, we review the state of the art of energy routing algorithms. We first introduce the concept of energy routing and then, we present a comprehensive literature survey of existing energy routing algorithms. Furthermore, we provide a discussion of our findings and future directions.
