Improved Active and Reactive Energy Forecasting Using a Stacking Ensemble Approach: Steel Industry Case Study

Energies, Journal Year: 2023, Volume and Issue: 16(21), P. 7252 - 7252

Published: Oct. 25, 2023

The prevalence of substantial inductive/capacitive loads within the industrial sectors induces variations in reactive energy levels. imbalance between active and network leads to heightened losses, diminished efficiency, an associated escalation operating costs. Therefore, forecasting sector confers notable advantages, including cost reduction, operational safeguarding equipment, enhanced consumption management, more effective assimilation renewable sources. Consequently, a range specialized methods for different applications have been developed address these challenges effectively. This research proposes stacked ensemble methodology, denoted as Stack-XGBoost, leveraging three distinct machine learning (ML) methods: extra trees regressor (ETR), adaptive boosting (AdaBoost), random forest (RFR), foundational models. Moreover, incorporation extreme gradient (XGBoost) algorithm meta-learner serves amalgamate predictions generated by base models, enhancing precision active/reactive using real time data steel industry. To assess efficacy proposed model, diverse performance metrics were employed. results show that Stack-XGBoost model outperformed other methods. Additionally, sensitivity analysis was conducted robustness method against input parameters.

Optimization of Operation Strategy of Multi-Islanding Microgrid Based on Double-Layer Objective

Energies, Journal Year: 2024, Volume and Issue: 17(18), P. 4614 - 4614

Published: Sept. 14, 2024

The shared energy storage device acts as an hub between multiple microgrids to better play the complementary characteristics of microgrid power cycle. In this paper, cooperative operation process participating in island systems is researched, and two-stage research on multi-microgrid mode optimization service cost focused on. first stage, output each subject determined with goal profit optimal capacity, modified grey wolf algorithm used solve problem. second income distribution problem transformed into a negotiation bargaining process. are two sides game. Combined non-cooperative game theory, alternating direction multiplier method reduce cost. simulation results show that can optimize allocation multi-party resources by flexibly adjusting control mode, improving efficiency resource utilization while consumption renewable energy, meeting demand all parties, realizing sharing resources. Simulation compared traditional PSO algorithm, iterative times GWO proposed paper reduced 35.62%, calculation time shortened 34.34%. Compared common number iterations 18.97%, 22.31%.

Security challenges in civil registration: safeguarding vital information in an evolving landscape

World Journal of Advanced Research and Reviews, Journal Year: 2023, Volume and Issue: 19(1), P. 1051 - 1071

Published: July 26, 2023

Civil registration is a fundamental process that captures vital events such as births, deaths, marriages, and divorces, enabling governments to create accurate demographic databases deliver essential services their citizens. However, in today's digital age, civil systems face numerous security challenges jeopardize the integrity confidentiality of information. This paper highlights some key encountered outlines potential strategies address them. Firstly, digitization processes has opened new avenues for cyber threats. Malicious actors may attempt compromise databases, manipulate or steal records, disrupt through cyberattacks. Robust cybersecurity measures, including encryption, firewalls, intrusion detection systems, regular audits, are safeguard sensitive data ensure continuity operations. Secondly, issue identity theft poses significant challenge security. Fraudulent practices, creation fake identities alteration existing can undermine trustworthiness system lead misallocation resources. The implementation verification mechanisms, biometrics unique identifiers, enhance accuracy while reducing risk fraud. Thirdly, ensuring privacy individuals' personal information critical systems. With increasing interconnectedness data, there heightened unauthorized access breaches. Strong protection regulations, robust controls, encryption techniques help mitigate these risks, fostering public trust confidence processes. Moreover, inclusivity must be addressed effectiveness reliability Marginalized populations, refugees, migrants, those residing remote areas, barriers accessing services, leaving them vulnerable identity-related challenges. Deploying mobile units, leveraging innovative technologies, promoting community engagement improve extend benefits all individuals.
