Special Issue Information

Dear Colleagues,

Nowadays, machine learning (ML) has been an integral part of scientific and technological progress. Various ML methods have the potential to offer tools for learning, knowledge discovery, and decision-making that can outperform human abilities and can be used in a large number of application domains. Especially, applied machine learning (AML) focuses on implementing machine learning algorithms to solve practical engineering challenges whose key characteristics include domain-specific applications, engineering integration, and trend evolution. Soft computing (SC), closely related to ML, represents computational methods that tolerate uncertainty and imprecision to achieve robust, low-cost solutions. Then, integration of AML and SC drives cutting-edge research such as enhanced robustness, explainable AI, and efficiency optimization. Novel machine learning methods integrated with intelligent optimization and various soft computing techniques, hybrid and deep learning methods, and ensemble techniques are quickly emerging and deliver models with higher accuracy.

As a response to the recent advancements, the objective of this Special Issue is to present a collection of notable methods and applications of recent theoretical and computational studies on AML and SC. We invite scientists from all around the world to contribute to developing a comprehensive collection of papers on the progressive and high impact of AML and SC.

Considering the global objective of carbon emission reduction, this paper focuses on optimizing the operational efficiency of grid-connected electric vehicles (EVs) and promoting sustainable energy integration and thus proposes a novel dual-incentive mechanism combining real-time pricing (RTP) and carbon quotas. A core of this study is the development of a bilevel programming model that effectively captures the strategic interaction between power suppliers (PS) and microgrid (MG) users. At the upper level, the model enables the PS to optimize electricity prices, achieving both revenue maximization and grid balance maintenance; at the lower level, it supports MGs in rational scheduling of EV charging/discharging, photovoltaic and wind energy (PWE) utilization, and load consumption, ensuring the fulfillment of user demands while maximizing MG profits. To address the non-convex factors in the model that hinder an efficient solution, another key is the design of a bilevel distributed genetic algorithm, which realizes efficient decentralized decision making and provides technical support for the practical application of the model. Through comprehensive simulations, the study verifies significant quantitative outcomes. The proposed algorithm converges after only 61 iterations, ensuring efficient solution performance. The average purchase price of electricity from the PS for the MG is USD 1.1, while the selling price of PWE sources from MG for the PS is USD 0.6. This effectively promotes the MG to prioritize the consumption of PWE sources and encourages the PS to repurchase the electricity generated by PWE sources. On average, carbon emissions decreased by approximately 300 g each time slot, and the average amount of carbon trading was around USD 8. Ultimately, this research delivers a practical and impactful solution for the development of MGs and the advancement of carbon reduction goals. Full article
