“…However, there is a crucial requirement of protecting the distribution network operations with advanced technologies and timing tools to enhance the resilience and robustness of the distribution system. In distribution system networks, synchronization measurements have been essential for resolving different applications such as power quality measurement, stability assessment, fault location, state estimation, system topology detection, and event detection [15], [16]. Depending on the purpose of the applications, the required accuracy of the timestamps differs [17].…”

The monitoring and control of power distribution systems requires an accurate and stable time synchronization infrastructure. The major requirement for a time synchronization system is sharing a global time throughout the network. This article provides an overview of the synchronization techniques implemented in power distribution systems. The implementation of different techniques for time synchronization due to heterogeneous communication infrastructure creates various challenges in the system. Therefore, this article aims to propose a homogeneous, uniform approach for a network-based synchronization mechanism in or to implement multiple distribution system applications. For this purpose, the precision time protocol (PTP), IEEE 1588, is tested experimentally for various time criticality with an Ethernet-based communication network. The testbed uses single board computers to explore different criticality of the timestampings for IEEE 1588 (PTP) to determine how various applications need different type of timestamping depending upon the performance, cost, and accuracy requirements. These different levels of timestamping requirements for synchronization affect the performance of a range of nextgeneration distribution system applications. The proposed solution provides monitoring for each application using only a single time synchronization technique with an Ethernet-based network.

“…The time required for processing a single Elliptic Curve Point Multiplication (ECPM) is 0.97 ms; bilinear pairing is 14.90 ms; pairing-based point multiplications is 4.31 ms; modular exponentiation is 1.25 ms [33]. The Hyperelliptic Curve Divisor Multiplication (HCDM) is assumed to be 0.48 milliseconds [34][35][36][37][38]. Multi-precision Integer and Rational Arithmetic C Library (MIRACL) [39] is used to measure the computational performance.…”

Internet of Vehicles (IoV) is a specialized breed of Vehicular Ad-hoc Networks (VANETs) in which each entity of the system can be connected to the internet. In the provision of potentially vital services, IoV transmits a large amount of confidential data through networks, posing various security and privacy concerns. Moreover, the possibility of cyber-attacks is comparatively higher when data transmission takes place more frequently through various nodes of IoV systems. It is a serious concern for vehicle users, which can sometimes lead to life-threatening situations. The primary security issue in the provision of secure communication services for vehicles is to ensure the credibility of the transmitted message on an open wireless channel. Then, receiver anonymity is another important issue, i.e., only the sender knows the identities of the receivers. To guarantee these security requirements, in this research work, we propose an anonymous certificateless signcryption scheme for IoV on the basis of the Hyperelliptic Curve (HEC). The proposed scheme guarantees formal security analysis under the Random Oracle Model (ROM) for confidentiality, unforgeability, and receiver anonymity. The findings show that the proposed scheme promises better security and reduces the costs of computation and communication.

Smart grids have brought new possibilities in power grid operations for control and monitoring. For this purpose, state estimation is considered as one of the effective techniques in the monitoring and analysis of smart grids. State estimation uses a processing algorithm based on data from smart meters. The major challenge for state estimation is to take into account this large volume of measurement data. In this article, a novel smart distribution network state estimation algorithm has been proposed. The proposed method is a combined high-gain state estimation algorithm named adaptive extended Kalman filter (AEKF) using extended Kalman filter (EKF) and unscented Kalman filter (UKF) in order to achieve better intelligent utility grid state estimation accuracy. The performance index and the error are indicators used to evaluate the accuracy of the estimation models in this article. An IEEE 37-node test network is used to implement the state estimation models. The state variables considered in this article are the voltage module at the measurement nodes. The results obtained show that the proposed hybrid algorithm has better performance compared to single state estimation methods such as the extended Kalman filter, the unscented Kalman filter, and the weighted least squares (WLS) method.
