“…Zhang et al [35] discuss three use cases of SDN in smart grids, i.e., content-based data exchange, virtual networks for distributed energy resource (DER) aggregation, and smart building management. Goodney et al [9] propose an efficient multicast SDN system that connects high-rate PMUs and data subscribers with different data rate requirements. Molina et al [20] and Cahn et al [5] propose to integrate SDN with IEC-61850-based substation automation systems.…”

“…Several studies [5,9,14,20,35] advocate adopting SDN to enrich functionality and improve QoS of smart grid communication networks by leveraging SDN's run-time configurability. While QoS is an important issue, system resilience, i.e., the ability of a system to recover and maintain critical services despite accidental failures and malicious attacks, is also a key consideration for critical infrastructures like power grids.…”

Software-defined networking (SDN) is an emerging networking paradigm that provides unprecedented flexibility in dynamically reconfiguring an IP network. It enables various applications such as network management, quality of service (QoS) optimization, and system resilience enhancement. Pilot studies have investigated the possibilities of applying SDN on smart grid communications, while the specific benefits and risks that SDN may bring to the resilience of smart grids against accidental failures and malicious attacks remain largely unexplored. Without a systematic understanding of these issues and convincing validations of proposed solutions, the power industry will be unlikely to embrace SDN, since resilience is always a key consideration for critical infrastructures like power grids. In this position paper, we aim to provide an initial understanding of these issues, by investigating (1) how SDN can enhance the resilience of typical smart grids to malicious attacks, (2) additional risks introduced by SDN and how to manage them, and (3) how to validate and evaluate SDN-based resilience solutions. Our goal is also to trigger more profound discussions on applying SDN to smart grids and inspire innovative SDN-based solutions for enhancing smart grid resilience.Permission to make digital or hard copies of all or part of this work for personal or classroom use is granted without fee provided that copies are not made or distributed for profit or commercial advantage and that copies bear this notice and the full citation on the first page.

“…According to some smart grid researchers [12][13][14][15], communication technologies first need to be further developed, and they predict that software-defined networking (SDN) will allow information exchange in different network platforms, different layers and provide the adaption of new business models of the smart grid without hardware replacement. In addition, they argue that the SDN-based smart grid will improve the system robustness by enhancing the reliability and optimization of the transmission asset utilization [13,15]. In the SDN architecture, the control plane of the network is controlled by using a centralized SDN controller, and a service provider can identify not only the network status, but can also flexibly make a network plan for services and business models.…”

Context and situational awareness are key features and trends of the smart grid and enable adaptable, flexible and extendable smart grid services. However, the traditional hardware-dependent communication infrastructure is not designed to identify the flow and context of data, and it focuses only on packet forwarding using a pre-defined network configuration profile. Thus, the current network infrastructure may not dynamically adapt the various business models and services of the smart grid system. To solve this problem, software-defined networking (SDN) is being considered in the smart grid, but the design, architecture and system model need to be optimized for the smart grid environment. In this paper, we investigate the state-of-the-art smart grid information subsystem, communication infrastructure and its emerging trends and potentials, called an SDN-enabled smart grid. We present an abstract business model, candidate SDN applications and common architecture of the SDN-enabled smart grid. Further, we compare recent studies into the SDN-enabled smart grid depending on its service functionalities, and we describe further challenges of the SDN-enabled smart grid network infrastructure.

Smart grids depend on a solid foundation of communications. Although standards like IEC 61850 proposes interoperability, autoconfiguration, and autonomous control solutions for the communication network, there are still open problems on how to efficiently forward high priority sensitive data. This work proposes a complete architecture for autonomic management and control of communication networks for substations based on IEC 61850. The proposed solution, called SMARTFlow, uses OpenFlow in order to achieve granularity and flexibility in the treatment of data flows. SMARTFlow proactively calculates Layer 2 multicast trees to forward the high priorities GOOSE and Sampled Values messages and reconfigures all flow entries in case of network failures. Also, the proposed system monitors the network and defines the configuration of client-server flows on-demand. The proposal was implemented and tested using Mininet and showed a total load up to 44 % lower than the load using typical switches.
