Special Issue Information

Dear Colleagues,

Power systems are some of the most critical infrastructures in modern society; however, recent years have seen many blackouts caused by extreme events, including natural disasters and man-made attacks (e.g., the Texas freeze, Indian heatwaves, and terrorist attacks). With an increasing awareness of such threats, the resilience and security of modern power systems are receiving an increasing amount of attention, which focuses on the ability of power systems to prepare for and adapt to changing conditions as well as withstand and recover rapidly from disruptions. In the meantime, with the high penetration of renewable energy, the way power systems operate is more complex and variable, posing great challenges to the resilience and security of modern power systems. Therefore, to mitigate the damage caused by extreme events and ensure the safe and reliable operation of power systems, it is of great significance to explore key technologies (such as resilience evaluation methods and resilience improvement methods) under the complex influence of extreme events and high renewable penetration. This Special Issue aims to address these challenges and key technologies for improving the resilience of power systems. Topics of interest for publication include, but are not limited to, the following:

  • Evaluation methods for power system resilience;
  • Vulnerability modelling of power systems under extreme events or high renewable penetration;
  • Resilient operation and control of power systems;
  • Recovery and restoration strategies for resilience enhancement;
  • Planning of resilient power systems;
  • Resilience of power systems with high renewable penetration;
  • Resilience of hybrid AC/DC power systems;
  • Resilience of multienergy systems/integrated energy systems;
  • Resilience of cyber–physical systems;
  • Big data and artificial intelligence approaches for resilience enhancement.

With the development of distribution networks, the widespread use of communication devices has exposed these networks to the risk of cross-domain attacks. Based on the coupling relationship between power and communication networks, a method for the optimal allocation of distribution network resources considering this coupling is proposed. In the resource allocation stage, given the limited availability of resources, optimal allocation is carried out for resources such as distributed generations and remote-controlled switches; additionally, the resilience of the distribution network is enhanced through the reinforcement of both the distribution lines and communication links. In the prevention stage, in advance of extreme events, preventive islanding is formed through switch operations. In the degradation stage, the distribution network identifies faulted and non-faulted areas based on the fault propagation model, while the communication network assesses the fault status of communication nodes based on the virtual flow model. In the recovery stage, coordinated control of remote-controlled switches and distributed generations with normal communication is implemented for network reconfiguration to minimize load losses. Finally, the effectiveness of the proposed method is verified through the IEEE 33-node system. Full article

The smart grid (SG) is an efficient and reliable framework capable of controlling computers, automation, new technologies, and devices. Advanced metering infrastructure (AMI) is a crucial part of the SG, facilitating two-way communication between users and service providers (SPs). Computation, storage, and communication are extremely limited as the AMI’s device is typically deployed outdoors and connected to an open network. Therefore, an authentication and key agreement protocol is necessary to ensure the security and confidentiality of communications. Existing research still does not meet the anonymity, perfect forward secrecy, and resource-limited requirements of the SG environment. To address this issue, we advance a lightweight authentication and key agreement scheme based on elliptic curve cryptography (ECC). The security of the proposed protocol is rigorously proven under the random oracle model (ROM), and was verified by a ProVerif tool. Additionally, performance comparisons validate that the proposed protocol provides enhanced security features at the lowest computation and communication costs. Full article
