“…SDN can facilitate and improve the networking of many (up to a hundred) intelligent electric devices (IEDs) in a substation, by shortest path forwarding, multicast traffic reduction, load balancing, etc. Kim et al [14] propose to use OpenFlow switches to form virtual local-area networks (VLANs) for multiple grid applications with different QoS requirements. For example, a PMU data collection tree desires smaller depth because of stringent real-time requirements, while a consumer meter data collection tree prefers smaller width due to the limited flow table memory in current off-the-shelf OpenFlow switches.…”

“…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.

Riding on the success of SDN for enterprise and data center networks, recently researchers have shown much interest in applying SDN for critical infrastructures. A key concern, however, is the vulnerability of the SDN controller as a single point of failure. In this paper, we develop a cyberphysical simulation platform that interconnects Mininet (an SDN emulator), hardware SDN switches, and PowerWorld (a high-fidelity, industry-strength power grid simulator). We report initial experiments on how a number of representative controller faults may impact the delay of smart grid communications. We further evaluate how this delay may affect the performance of the underlying physical system, namely automatic gain control (AGC) as a fundamental closed-loop control that regulates the grid frequency to a critical nominal value. Our results show that when the fault-induced delay reaches seconds (e.g., more than four seconds in some of our experiments), degradation of the AGC becomes evident. Particularly, the AGC is most vulnerable when it is in a transient following say step changes in loading, because the significant state fluctuations will exacerbate the effects of using a stale system state in the control.

This paper introduces an innovative energy management system architecture for Smart Grids, designed in the European 7th framework program project e-balance. The architecture is hierarchical and fractal-like, which results in better scalability and reuse of algorithms and programming code for energy management. It supports both micro-grids and distributed energy resources. The system is structured into two main parts -the communication platform and the energy management platform. The former provides a common data exchange layer, while the latter provides the local energy management logic, currently supporting energy balancing and grid resilience services. The system is being deployed in two pilots: in Portugal and in the Netherlands, where use cases on energy balancing, grid monitoring and grid reliability will be demonstrated.
