“…The global visibility and runtime programmability enabled by SDN technologies introduce unprecedented capabilities to guard a communication network adequately against cyber incidents. More specifically, the global visibility boosts the efficiency and effectiveness of networkwide traffic management, while the runtime programmability enables the SDN controller to adjust traffic management schedules on demand [52]. Besides, SDN technologies realize the per-flow micromanagement that is especially useful for checking the data integrity while ensuring the timeliness of data transmission.…”

This paper provides a strategic solution for enhancing the cybersecurity of power distribution system operations when information and operation technologies converge in active distribution network (ADN). The paper first investigates the significance of Internet of Things (IoT) in enabling fine-grained observability and controllability of ADN in networked microgrids. Given severe cybersecurity vulnerabilities embedded in conventionally centralized energy management schemes, the paper then proposes a cyber-secure decentralized energy management framework that applies a distributed decision-making intelligence to networked microgrids while securing their individual mandates for optimal operation. In particular, the proposed framework takes advantage of software-defined networking technologies that can secure communications among IoT devices in individual microgrids, and exploits potentials for introducing blockchain technologies that can preserve the integrity of communications among networked microgrids in ADN. Furthermore, the paper presents the details of application scenarios where the proposed framework is employed to secure peer-to-peer transactive energy management based on a set of interoperable blockchains. It is finally concluded that the proposed framework can play a significant role in enhancing the efficiency, reliability, resilience, and sustainability of electricity services in ADN.The development toward ADN has been driven by grid modernization requests for sustainable, flexible, secure, efficient, reliable, resilient electricity services at the power distribution level. As shown in Fig. 1, technological and Cyber-secure decentralized energy management for IoT-enabled active distribution networks 901

The present-day power system is a complex network that caters to the demands of several applications with diverse energy requirements. Such a complex network is susceptible to faults caused due to several reasons such as the failure of the equipment, hostile weather conditions, etc. These faults if not detected in the real-time may lead to cascading failures resulting in a blackout. These blackouts have catastrophic consequences which result in a huge loss of resources. For example, a blackout in 2004 caused an economic loss of 10 billion U.S dollars as per the report of the Electricity Consumers Resource Council. Subsequent investigation of the blackout revealed that the catastrophe could have been prevented if there was an early warning system. Similar other blackouts across the globe forced the power system engineers to devise an effective solution for real-time monitoring and control of the power system. The consequence of these efforts is the wide area measurement system (WAMS). The WAMS consists of several sensors known as the phasor measurement units (PMUs) that collect the real information pertaining to the health of the power grid. This information in the form time synchronized voltage and current phasors is communicated to the central control center or the phasor data concentrator (PDC) where the data is analyzed for detection of power system anomalies. The communication of the synchrophasor data from each PMU to the PDC constitutes the synchrophasor communication system (SPCS). Thus, the SPCS can be considered as the edifice of the WAMS and its reliable operation is essential for the effective monitoring and control of the power system. This paper presents a comprehensive review of the various synchrophasor communication technologies, communication standards and applications. It also identifies the existing knowledge gaps and the scope for future research work.

“…Taha et al (2016) utilized real-time measurements from PMUs to develop a robust dynamic state estimator against attacks. Given that PMUs can also be damaged in cyber-physical systems, Mousavian et al (2015) proposed a mixed-integer linear programming model to prevent risk propagation and maintain the system observability, and Lin et al (2016) formulated an integer linear programming model to exploit the features of dynamic and programmable configuration in a software-defined networking infrastructure to achieve resilience against cyber-attacks. Distributed computation has also been introduced into system operation decision making because it provides scalability, robustness, and privacy protection (Duan et al, 2016a).…”

Boosting the resilience of power systems is a core requirement of smart grids. In fact, resilience enhancement is crucial to all critical infrastructure systems. In this study, we review the current research on system resilience enhancement within and beyond smart grids. In addition, we elaborate on resilience definition and resilience quantification and discuss several challenges and opportunities for system resilience enhancement. This study aims to deepen our understanding of the concept of resilience and develop a wide perspective on enhancing the system resilience for critical infrastructures.
