“…These two studies found that switching power in the form of packets is possible. Most of the other studies conducted on this area include power routers [17,[49][50][51], power routing algorithms [19,[52][53][54][55][56][57][58] and architectures [59][60][61]. The next two subsections discuss power routers and power routing algorithms in details.…”

“…Recent studies that have been concerned with power routers include [17,[49][50][51]. Abe et al [17] proposed a power router that segments the synchronized wide-area power grid into smaller asynchronous grids which are connected together using multiple IP addressed ACs/DC/ACs converters called Digital Grid Routers.…”

Due to the expansion of distributed renewable energy resources, peer to peer energy trading (P2P DET) is expected to be one of the key elements of next generation power systems. P2P DET can provide various benefits such as creating a competitive energy market, reducing power outages, increasing overall efficiency of power systems and supplementing alternative sources of energy according to user preferences. Because of these promising advantages, P2P DET has attracted the attention of several researchers. Current research related to P2P DET include demand response optimization, power routing, network communication, security and privacy. This paper presents a review of the main research topics revolving around P2P DET. Particularly, we present a comprehensive survey of existing demand response optimization models, power routing devices and power routing algorithms. We also identify some key challenges faced in realizing P2P DET. Furthermore, we discuss state of the art enabling technologies such as Energy Internet, Blockchain and Software Defined Networking (SDN) and we provide insights into future research directions.

“…To avoid ambiguity, we use PFR to refer to a device that is able to manage multiple power flows, and PFC to one that can only adjust the power flow through one branch or appliance. In our previous work [8], a generic functional model of a PFR that represents the conventional bus has been proposed. In this paper, we use a PFR model [8] shown in Fig.…”

“…Power flow routing is enabled by power flow controllers (PFCs), e.g., flexible alternating-current transmission system (FACTS) devices [3], and power flow routers (PFRs) [8]. Due to the development of power electronic over the past two decades, power flow routing is becoming mature and costeffective for improving asset utilization [7], [9].…”

The uncertainty and variability of renewable energy sources are challenging problems in the operation of power systems. In this paper, we focus on the robust dispatch of generators to overcome the uncertainty of renewable power predictions. The energy management costs of supply, spinning reserve, and power losses, are jointly optimized by the proposed robust optimal power flow (OPF) method with a column-andconstraint generation algorithm. Conic relaxation is applied to the non-convex alternating-current power flow regions with the phase angle constraints for loops retained by linear approximation. The proposed method allows us to solve the robust OPF problem efficiently with good accuracy and to incorporate power flow controllers and routers into the OPF framework. Numerical results on the IEEE Reliability Test System show the efficacy of our robust dispatch strategy in guaranteeing immunity against uncertain renewable generation, as well as in reducing the energy management costs through power flow routing.
