Abstract

The current power grid is no longer a feasible solution due to ever-increasing user demand of electricity, old infrastructure, and reliability issues and thus require transformation to a better grid also known as, smart grid (SG). The key features that distinguish SG from the conventional electrical power grid are its capability to perform two-way communication, demand side management, and real time pricing. Despite all these advantages that SG will bring, there are certain issues which are specific to SG communication (SGC) system. For instance, network management of current SG systems is complex, time consuming, and done manually. Moreover, SGC system is built on different vendor specific devices and protocols. Therefore, the current SG systems are not protocol independent, thus leading to interoperability issue. Software defined network (SDN) has been proposed to monitor and manage the communication networks globally. By separating the control plane from the data plane, SDN helps the network operators to manage the network flexibly. Since SG heavily relies on communication networks, therefore, SDN has also paved its way into the SG. By applying SDN in SG systems, efficiency and resiliency can potentially be improved. SDN, with its programmability, protocol independence, and granularity features, can help the SG to integrate different SG standards and protocols, to cope with diverse communication systems, and to help SG to perform traffic flow orchestration and to meet specific SG quality of service requirements. This paper serves as a comprehensive survey on SDN-based SGC. In this paper, we first discuss taxonomy of advantages of SDN-based SGC. We then discuss SDN-based SGC architectures, along with case studies. This paper provides an in-depth discussion on routing schemes for SDN-based SGC. We also provide detailed survey of security and privacy schemes applied to SDN-based SGC. We furthermore present challenges, open issues, and future research directions related to SDN-based SGC.

Additional Information:	Funding Information: The global environment for network innovation (GENI) [110] is a testbed facility provided by National Science Foundation (NSF), USA, to the researchers to evaluate thier newly developed algorithms and prototypes. GENI testbed also supports the programmability facility as SDN (OpenFlow), which is the integral part of it. Using GENI and considering the strict deadline of two weeks, the authors in [109] deployed an OpenFlow SDN controller for SG DR application. In this regard, authors developed two algorithms: a control logic algorithm for load shedding and the second algorithm for link failure. The goal was to see if MPLS-like functionalities can be achieved or not in commercially available hardware switches through SDN and it was shown that such functionalities can be achieved easily. The deployed SDN controller is capable of guaranteeing the required QoS, provides fast failover mechanism, and supports load balancing.
