Given the strict hierarchical coordination inherent in relay protection systems, there exists a precise temporal constraint relationship among alarm signals. A forward and reverse temporal inference mechanism is introduced to meticulously scrutinize each alarm signal, thereby refining the initial confidence levels of abnormal alarm data. Building upon the interplay between protection devices and circuit breakers, an intuition fuzzy Petri net model imbued with temporal constraints is constructed.

They pose significant safety hazards, necessitating swift detection and mitigation to maintain electrical infrastructure integrity and ensure continuous power supply. Hence, accurate detection and categorization of electrical faults are pivotal for optimized power system maintenance and operation. In this work, we propose a novel approach for detecting and categorizing electrical faults using the Hessian locally linear embedding (HLLE) technique and subsequent clustering with t-SNE (t-distributed stochastic neighbor embedding) and Gaussian mixture model (GMM). First, we employ HLLE to transform high-dimensional (HD) electrical data into low-dimensional (LD) embedding coordinates. This technique effectively captures the inherent variations and patterns in the data, enabling robust feature extraction. Next, we perform the Mann–Whitney U test based on the feature space of the embedding coordinates for fault detection. This statistical approach allows us to detect electrical faults providing an efficient means of system monitoring and control. Furthermore, to enhance fault categorization, we employ t-SNE with GMM to cluster the detected faults into various categories. To evaluate the performance of the proposed method, we conduct extensive simulations on an electrical system integrated with solar farm. Our results demonstrate that the proposed approach exhibits effective fault detection and clustering across a range of fault types with different variations of the same fault. Overall, this research presents an effective methodology for robust fault detection and categorization in electrical systems, contributing to the advancement of fault management practices and the prevention of system failures.</div></div>","PeriodicalId":100897,"journal":{"name":"Measurement: Energy","volume":"5 ","pages":"Article 100035"},"PeriodicalIF":0.0,"publicationDate":"2025-01-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143154179","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite the effective forecasting capabilities of LSTM networks in predicting periodic energy consumption data, they are hindered by the dead region effect, which is caused by the sigmoid and hyperbolic tangent activation functions. These functions control the flow of information and determine which data is suitable for updating and learning within specific boundaries, but they also create unused regions that impact the accuracy and efficiency of the learning process in LSTM networks. To address this issue, this study introduces an Internet of Things (IoT) energy consumption forecasting model based on an improved long short-term memory (ILSTM) approach. This model aims to overcome the dead region problem and enhance the accuracy and learning process of traditional LSTM networks. The study collected actual energy consumption data from a residential building using a CT (SCT-013-030) sensor and ESP8266 NodeMCU real model with the Thingspek cloud platform for data processing. Additionally, a storage data recycling (SDR) technique is utilized to address data clustering shortages and fill missing information. The ILSTM forecasting model was assessed using various evaluation metrics including mean absolute error (MAE), mean square error (MSE), and root mean square error (RMSE). Additionally, comparisons were made between the throughput, latency, and bill information of the proposed ILSTM forecasting model and the ARIMA, DBN Regression, and conventional LSTM (CLSTM) forecasting models. The evaluation demonstrated that the ILSTM network outperformed the CLSTM network, showing improvements of 61.697% in MAE, 59.248% in MSE, and 50.537% in RMSE. Furthermore, the ILSTM network exhibited lower throughput values for varying energy consumption data compared to the CLSTM, and demonstrated reduced latency compared to ARIMA, DBN Regression, and CLSTM by 40.1, 21.1, and 13.5 cycles, respectively. Lastly, the results revealed that the ILSTM network provided more accurate energy consumption forecasting and bill estimation than the CLSTM.</div></div>","PeriodicalId":100897,"journal":{"name":"Measurement: Energy","volume":"5 ","pages":"Article 100033"},"PeriodicalIF":0.0,"publicationDate":"2025-01-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143154181","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is increasingly essential for countries to review and update their power loss policies to deliver electrical energy to consumers at the most feasible and economical rates. The performance of Low Voltage Distribution Networks (LVDN) often falls short, resulting in high voltage fluctuations and significant energy losses for end consumers in 0.4 kV systems. This research aims to address these issues by minimizing energy losses and enhancing the voltage profile of the 0.4 kV distribution network. Various rehabilitation techniques have been employed to significantly improve the efficiency of the LVDN. Since most energy losses are directly associated with the LVDN, two 0.4 kV distribution networks in the villages of New Kalyam and Upper Tharjial in the Mandra Sub-Division, under Islamabad Electricity Supply Corporation (IESCO), Pakistan, were selected as case studies. Field surveys were conducted in collaboration with the local utility staff to collect actual data. The analysis was performed using computer-aided tools, including the Computer-Aided Distribution Planning and Design (CADPAD) software and Energy Loss Reduction (ELR) programs. The proposed methodology is straightforward and practical. The case study results demonstrate significant improvements in the voltage profile and reductions in energy losses within the LVDN.

We propose a novel sensing approach for solvent monitoring using planar microwave sensors. The proposed sensor consists of a chipless tag-reader pair communicating wirelessly using electromagnetic coupling. The sensor has a high sensitivity response to variations in permittivity at various solvent concentrations, which is reflected in the resonance-frequency spectrum. To maximize repeatability response of sensor, the sensor is integrated into a plastic container to form a sensing probe that can be used as an on-site in-line instrument. The experiments were conducted using four solvents, including n-pentane, n-hexane, n-heptane, and ethyl acetate. The results demonstrated that when solvent concentration changes from zero to 20 wt%, the frequency shift of resonance peak changes by 2.71, 2.01, 1.66, and 2.10 MHz for the examined solvents, respectively, indicating an exceptional capability of real-time monitoring for measuring solvents in oleic phase.
