Special Issue Information

Dear Colleagues,

A real-time cyber–physical system for Smart Grid (SG) must integrate and process real-time data from generation, distribution, and consumption facilities. The systems involved must have real time monitoring, communication, computing, and cloud storage capabilities.

It is important to adjust the response times of each of these stages in order to have a time resolution that guarantees rapid intervention in critical situations.

There is currently a trend towards the application of Edge Computing (EC) with the incorporation of equipment located in the same facilities as edge nodes that act in a second processing phase to contribute to the optimisation of production or for the rapid detection of abnormal operating conditions. 

In SG, EC can guarantee response times in accordance with the requirements of the main international standards such as IEEE 1547.1-2005 for the interconnection of distributed resources, IEEE 929-2000 and IEC 61727-2004 for the optimal interconnection of photovoltaics in residential sectors, and DIN VDE V 0126-1-1:2012 for the disconnection of the generation grid.

In this context, it is advisable to use measurement systems such as micro-phasor measurement units and power quality monitoring, which enable generating edge databases with a higher temporal resolution and with storage in an edge–cloud framework. EC requires that storage, processing, and computing take place at the edge of the network. In this framework, techniques to improve the captures sync and data sync are of relevance. Therefore, it is interesting to contribute to SG with EC techniques to manage critical events and the bidirectional control of energy flow, and to combine advanced cloud analytics techniques with artificial intelligence, machine learning, and deep learning.

For this reason, this Special Issue is dedicated to research that may represent an advance in any of the proposed challenges such as the improvement of response times with edge computing, cloud analytics techniques for the optimisation of production, techniques that allow for the development of edge–grid applications for consumption close to the generation site, the adoption of measures to guarantee response times according to standards, the application of transmission techniques with protocols such as IEC 61850 to facilitate the flow of information in real time, and all kinds of techniques that contribute to the coordination of renewable energy generation plants.

With the advancement of technology and time, people have always sought to solve problems in the most efficient and quickest way possible. Since the introduction of the cloud computing environment along with many different sub-substructures such as task schedulers, resource allocators, resource monitors, and others, various algorithms have been proposed to improve the performance of the individual unit or structure used in the cloud environment. The cloud is a vast virtual environment with the capability to solve any task provided by the user. Therefore, new algorithms are introduced with the aim to improve the process and consume less time to evaluate the process. One of the most important sections of cloud computing is that of the task scheduler, which is responsible for scheduling tasks to each of the virtual machines in such a way that the time taken to execute the process is less and the efficiency of the execution is high. Thus, this paper plans to propose an ideal and optimal task scheduling algorithm that is tested and compared with other existing algorithms in terms of efficiency, makespan, and cost parameters, that is, this paper tries to explain and solves the scheduling problem using an improved meta-heuristic algorithm called the Hybrid Weighted Ant Colony Optimization (HWACO) algorithm, which is an advanced form of the already present Ant Colony Optimization Algorithm. The outcomes found by using the proposed HWACO has more benefits, that is, the objective for reaching the convergence in a short period of time was accomplished; thus, the projected model outdid the other orthodox algorithms such as Ant Colony Optimization (ACO), Quantum-Based Avian Navigation Optimizer Algorithm (QANA), Modified-Transfer-Function-Based Binary Particle Swarm Optimization (MTF-BPSO), MIN-MIN Algorithm (MM), and First-Come-First-Serve (FCFS), making the proposed algorithm an optimal task scheduling algorithm.
