Special Issue Information

Dear Colleagues:

Various engineering technologies are being integrated into the construction of "smart cities" across multiple countries. Several subfields of engineering, such as the Internet of Things, mobile networks, smart grids, sixth-generation (6G) networks, intelligent transportation systems (ITSs), edge computing, autonomous vehicles, electrical cars, and artificial intelligence, to name a few, are converging to explore feasible alternatives to the existing paradigm. These emerging technologies will have a significant impact on the enhancement of smart cities. This will manifest in various ways, such as improving public transportation, mitigating traffic congestion, optimizing municipal services in terms of cost, ensuring the safety and well-being of citizens, minimizing energy usage, and mitigating pollution. Furthermore, these technologies are being combined and utilized by smart cities to achieve the environmental objectives of the Sustainable Development Goals. This convergence is known as "sustainable smart cities" and is recognized for its synergistic potential. However, designing, optimizing, implementing, and deploying those systems entail various challenges. One of the primary obstacles is ensuring the efficient operation of these systems in dynamic environments characterized by diverse conditions. Furthermore, it is imperative for collaborative smart city applications to effectively tackle concerns about the security and privacy of shared data.

This Special Issue seeks high-quality papers that advance both theoretical knowledge and practical implementations of future technologies in the context of sustainable smart cities. This feature topic aims to facilitate collaboration between academic and industrial researchers to analyze and address the key opportunities and challenges associated with the application of emerging technologies. The goal is to generate innovative solutions and valuable insights that can contribute to the design of modern and sustainable cities.

Abstract

Many power transformers throughout the world are nearing or have gone beyond their theoretical design life. Since these important assets represent approximately 60% of the cost of the substation, monitoring their condition is necessary. Condition monitoring helps in the decision to perform timely maintenance, to replace equipment or extend its life after evaluating if it is degraded. The challenge is to prolong its residual life as much as possible. Dissolved Gas Analysis (DGA) is a well-established strategy to warn of fault onset and to monitor the transformer’s status. This paper proposes a new intelligent system based on DGA; the aim being, on the one hand, to overcome the conventional method weaknesses; and, on the other hand, to improve the transformer diagnosis efficiency by using a four-step powerful artificial intelligence method. (1) Six descriptor sets were built and then improved by the proposed feature reduction approach. Indeed, these six sets are combined and presented to a Kohonen map (KSOM), to cluster the similar descriptors. An averaging process was then applied to the grouped data, to reduce feature dimensionality and to preserve the complete information. (2) For the first time, four direct Multiclass Support Vector Machines (M-SVM) were introduced on the Generic Model basis; each one received the KSOM outputs. (3) Dempster–Shafer fusion was applied to the nine membership probabilities returned by the four M-SVM, to improve the accuracy and to support decision making. (4) An output post-processing approach was suggested to overcome the contradictory evidence problem. The achieved AUROC and sensitivity average percentages of 98.78–95.19% (p-value < 0.001), respectively, highlight the remarkable proposed system performance, bringing a new insight to DGA analysis.
