The Internet of Things (IoT) refers to the latest iteration of the Internet, enabling communication and interaction among interconnected items. It is thriving and permeating every aspect of our life, including school, home, automobiles, and healthcare. IoT serves as a valuable aid in healthcare and plays a crucial role in a wide range of applications for monitoring medical services. Various wireless body area network devices and sensors offer real-time health monitoring services. The data produced by sensor-based devices requires secrecy, reliability, and end-to-end security in order to provide secure transmission across public networks. The implementation of IoT in healthcare will pose significant risks if patient information is not securely managed during transmission across unsecured networks or while stored by administrators. Recent research introduced an inflatable and anonymity-preserving user identification mechanism for IoT-based healthcare. Nonetheless, this technique was susceptible to certain attacks. These attacks compromise both the patients' medical data and their personal information. This study presents a security framework designed for real-time health monitoring systems with the objective of guaranteeing data secrecy, reliability, and security. This paper proposes AEAD (authentication, encryption and anomaly detection) approach for secure IoT healthcare monitoring. The authentication protocol is proposed based on the hash and XoR with biometric cryptographic operation. The medical data is encrypted using XoR based encoding scheme. Next an efficient machine learning based algorithm is used to detect the anomaly medical data. Different evaluation metrics (computational cost, encryption time, decryption time, and accuracy) are used to analyze the performance of the AEAD approach. The practical tests and analysis have demonstrated the practicality and efficacy of the monitoring system. The results indicate that it is capable of efficiently analyzing la

During the urban power grid (UPG) restoration process after a major power outage, unit restoration may be delayed due to the shortage of black-start resources. With the development of microgrids (MGs), various restoration resources are integrated into MGs. Taking full advantage of the restoration value of MGs and coordinating the restoration process of units and MGs can accelerate the restoration speed of UPG. This paper proposes a novel coordinated restoration method for MGs and UPG. Firstly, a distributed coordination scheme for unit restoration in UPG and service restoration in MGs is proposed. Then, taking into account of the restoration and operation constraints of power grid, the unit restoration model of UPG and MG service restoration model are constructed, respectively. Considering the independent management and information privacy of the UPG and MGs, a distributed optimization algorithm is adopted to solve the models. The effectiveness and superiority of the proposed method are verified using a coupling system.

The integration of distributed power sources into modern power grids has introduced significant network security challenges to Distributed power dispatch control Systems (DPDCS). These systems are critical for managing distributed energy resources (DERs), requiring real-time communication and coordination between control centers and distributed terminals. However, the openness and interconnectivity of DPDCS expose them to a variety of network security risks, including unauthorized access, malicious software attacks, and data breaches. This paper addresses the network security protection technology for the master side of DPDCS, focusing on software vulnerabilities, protocol interactions, device control, and security event analysis. We propose comprehensive solutions for network security recognition, vulnerability detection, information interaction security, and device state management. By employing state-of-the-art methods such as anomaly detection, automated vulnerability scanning, and multi-dimensional data analytics, this study aims to establish a robust foundation for securing distributed power dispatch systems. The implementation of these solutions is crucial for ensuring the stability and security of DPDCS in open interactive business environments. © 2025 IEEE.

This research aims to optimize a wind power generation prediction model based on machine learning to improve its accuracy and efficiency. Firstly, a variety of machine learning technologies, such as gated cycle unit GRU, artificial neural network (ANN), RMSE and other models, were used to model and predict wind power generation data. By mixing the predictions of these models, more accurate and robust predictions can be obtained. Second, the study combines statistical models such as time series analysis and regression models to capture trends and cyclical changes in wind power data. These statistical models can provide forecasts of long-term and short-term wind power generation trends, thereby enhancing the reliability of the overall forecast model. In addition, intelligent optimization algorithms, such as genetic algorithm and particle swarm optimization algorithm, are used to optimize the model parameters to further improve the prediction accuracy. Through the comprehensive use of machine learning, hybrid prediction, statistical model and intelligent optimization algorithm, this study is committed to creating an efficient and accurate wind power generation prediction model, providing a reliable forecasting tool for the wind power industry, and promoting the development and utilization of clean energy. © 2025 SPIE.

power communication networks are crucial for the safe and stable operation of power systems, supporting both real-time and non-real-time services. This paper introduces Software Defined Network (SDN) technology into power communication networks to meet demands for real-time performance, high efficiency, and security. SDN networks enable dynamic traffic optimization, achieving high bandwidth and low latency while offering flexibility and redundancy. However, the centralized nature of SDN controllers presents security challenges. To address these, this paper proposes zero-trust security policies and endpoint hardening measures. In the SDN-based power WLAN architecture, the SDN controller handles network management and control. The zero-trust model enhances security by enforcing strict authentication and authorization, reducing reliance on a centralized controller. Additionally, incorporating the WAPI (Wireless LAN Security Mandatory Standard) improves WiFi network security. To address WAPI’s inherent security flaws, a dynamic (R, N) threshold method for key storage is proposed, enhancing its applicability and security. Simulations verify the scheme’s performance, showing improved connection security and efficiency. The comprehensive security strategy strengthens the security performance of power communication networks, ensuring safe and stable power system operations. By integrating SDN technology, zero-trust authentication, and the WAPI standard, the network’s real-time performance, efficiency, and security are significantly enhanced. © 2024 Copyright held by the owner/author(s).

Hybrid energy storage system (HESS) can stabilize renewable energy power generation, but unreasonable energy storage power distribution and photovoltaic-load forecast errors will affect the economic benefits of the whole system. Aiming at the microgrid (MG) composed of photovoltaic (PV) and HESS, an energy management strategy (EMS) of MG considering forecast errors is proposed. Firstly, an optimization model considering the depreciation cost of battery is established. Secondly, day-ahead EMS is implemented under multiple operating modes considering minimum fluctuation and optimal economy. Then, according to the real-time forecast results and the feedback of system operation status, the intraday rolling energy management strategy (REMS) is developed to alleviate the impact of forecast errors. Finally, the real-time state of charge (SOC) of the supercapacitor (SC) is introduced to adjust the filter coefficient, which avoids the SC working in the charge/discharge restricted area for a long time and improves the adjustment effect. The results of the case analysis show that the proposed intraday REMS can effectively reduce the influence of forecast errors on energy management.

To address the variability in the scheduling timescale of electric and hydrogen energy and the high uncertainties caused by the high proportion of renewable energy, this paper proposes a two-layer multi-timescale rolling optimization method for electric-hydrogen hybrid energy storage systems (EH-HESS) considering renewable energy uncertainties. In the upper-layer long-timescale optimization, a fuzzy set of wind turbine (WT) and photovoltaic (PV) generation forecast errors is established based on the Wasserstein distance, and a distribution robust optimization (DRO) model is proposed for energy scheduling. In the lower-layer short-timescale optimization, typical scenarios are generated for the potential distribution of WT and PV generation. After receiving the upper-layer scheduling results, a short-timescale power scheduling model is established. The lower-layer scheduling results are passed back to the upper-layer to achieve a two-layer multi-timescale rolling optimization. Simulations show that the proposed method can achieve inter-day transfer of hydrogen energy, reduce the daily imbalanced electric energy and effectively suppress the fluctuation of WT and PV generation. Moreover, the method demonstrates notable economic benefits, higher by 21.71% and 18.87% respectively, than singletimescale energy storage and robust optimization (RO), enabling a balance between economy and robustness. Finally, a detailed sensitivity analysis is conducted to show the effect of the fuzzy set radius on the scheduling results.
