Special Issue Information

Dear Colleagues,

Due to the availability of sophisticated information and communication technology, it has become viable to collect data from a single component or from a whole system, which can be used later to gain valuable insights for smart decision making. The applications of data-driven decision-making can be found in numerous fields, including medicine, finance, transportation, industrial setup, etc. Data-driven intelligent decision making is also applicable in the energy sector. With the availability of a wide range of sensors and advanced algorithms of artificial intelligence, it is possible to develop strategies that can improve monitoring, efficiency, reliability, and control of energy systems. The devised strategies might just consist of simple statistical analysis of the data to perform a cost–benefit analysis and forecasting or to address a technical issue, for instance, fault detection diagnosis, and prognosis of energy systems.

This Special Issue aims to present original research papers with high quality and novelty and also review papers on “Data Analytics in Energy Systems”.

Topics of interest include but are not limited to:

Data analytics for energy system operation and control;
Multimodal data analytics and fusion;
Distributed data mining;
Artificial intelligence, machine learning, and deep learning for energy systems;
Cloud computing for data analytics in energy systems;
Data analytics for energy demand forecasting;
Data collection, visualization, statistical analysis, storage, and information management in energy systems;
Fault detection, diagnosis, and prognosis methodologies;
Model and fuzzy-based control design for smart power systems.

Abstract

An effective remaining useful life (RUL) estimation method is of great concern in industrial machinery to ensure system reliability and reduce the risk of unexpected failures. Anticipation of an electric motor’s future state can improve the yield of a system and warrant the reuse of the industrial asset. In this paper, we present an effective RUL estimation framework of brushless DC (BLDC) motor using third harmonic analysis and output apparent power monitoring. In this work, the mechanical output of the BLDC motor is monitored through a coupled generator. To emphasize the total power generation, we have analyzed the trend of apparent power, which preserves the characteristics of real power and reactive power in an AC power system. A normalized modal current (NMC) is used to extract the current features from the BLDC motor. Fault characteristics of motor current and generator power are fused using a Kalman filter to estimate the RUL. Degradation patterns for the BLDC motor have been monitored for three different scenarios and for future predictions, an attention layer optimized bidirectional long short-term memory (ABLSTM) neural network model is trained. ABLSTM model’s performance is evaluated based on several metrics and compared with other state-of-the-art deep learning models. Full article

Deep Learning Aided Data-Driven Fault Diagnosis of Rotatory Machine: A Comprehensive Review

by Shiza Mushtaq, M. M. Manjurul Islam and Muhammad Sohaib

Abstract

This paper presents a comprehensive review of the developments made in rotating bearing fault diagnosis, a crucial component of a rotatory machine, during the past decade. A data-driven fault diagnosis framework consists of data acquisition, feature extraction/feature learning, and decision making based on shallow/deep learning algorithms. In this review paper, various signal processing techniques, classical machine learning approaches, and deep learning algorithms used for bearing fault diagnosis have been discussed. Moreover, highlights of the available public datasets that have been widely used in bearing fault diagnosis experiments, such as Case Western Reserve University (CWRU), Paderborn University Bearing, PRONOSTIA, and Intelligent Maintenance Systems (IMS), are discussed in this paper. A comparison of machine learning techniques, such as support vector machines, k-nearest neighbors, artificial neural networks, etc., deep learning algorithms such as a deep convolutional network (CNN), auto-encoder-based deep neural network (AE-DNN), deep belief network (DBN), deep recurrent neural network (RNN), and other deep learning methods that have been utilized for the diagnosis of rotary machines bearing fault, is presented.
