Specifically, to address the practical limitation that communication links between subsystems of IMMPSs may be unavailable, we first formulate a sparse LQT problem in which the sparse patterns of controllers match the actual communication links. Meanwhile, in order to be applicable to real-time applications while overcoming model uncertainty caused by parameter variability common in IMMPSs models, we subsequently develop a data compression-based model-free PI algorithm for the abovementioned sparse LQT problem. The main advantages of this algorithm over existing algorithms for IMMPSs control are threefold: first, it has the ability to operate without a prior knowledge of system model, second, its embedded data compression significantly reduces the time consumption for controller design, making it suitable for real-time applications, and third, it designs controllers based on actual communication links, making it practical for applications where communication infrastructure may be constrained. Finally the efficacy of the proposed algorithm is verified through the IEEE 39-bus New England Power System.","PeriodicalId":55017,"journal":{"name":"IEEE Systems Journal","volume":"19 1","pages":"176-187"},"PeriodicalIF":4.0,"publicationDate":"2025-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143637951","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As an innovative approach, peer-to-peer (P2P) energy trading offers a promising solution to address these problems. In this article, we propose a bi-layer decentralized (BLD) optimization algorithm for P2P energy trading in multimicrogrids (MMG). Compared with traditional optimization algorithms that are single-layer decentralized (i.e., decentralizing solely at inter-MG trading and typically centralizing prosumers within the MG), the proposed algorithm achieves bi-layer decentralization (i.e., decentralization extends to both inter-MG and intra-MG trading). In this way, the BLD algorithm can significantly preserve the information privacy and decision independence of prosumers. In addition, the proposed algorithm can efficiently manage power flow in a decentralized manner at both layers, whereas existing decentralized algorithms frequently neglect this critical feature. Furthermore, an accelerated BLD (ABLD) algorithm is proposed to address time-consuming issues in this nested P2P trading for MMG. Numerical simulations on various test systems demonstrate the effectiveness of the proposed algorithm. The results indicate that the error of the proposed algorithm is below 0.1%. In addition, BLD requires 15602.03 s to converge with 560 prosumers, while ABLD only requires 228.05 s.","PeriodicalId":55017,"journal":{"name":"IEEE Systems Journal","volume":"19 1","pages":"282-293"},"PeriodicalIF":4.0,"publicationDate":"2025-02-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143645242","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the performance of these trained policies can be impacted when faced with diverse driving styles and personalities, particularly in highly interactive situations. This is because conventional MARL algorithms usually operate under the assumption of fully cooperative behavior among all agents and focus on maximizing team rewards during training. To address this issue, we introduce the personality modeling network (PeMN), which includes a cooperation value function and personality parameters to model the varied interactions in high-interactive scenarios. The PeMN also enables the training of a background traffic flow with diverse behaviors, thereby improving the performance and generalization of the ego vehicle. Our extensive experimental studies, which incorporate different personality parameters in high-interactive driving scenarios, demonstrate that the personality parameters effectively model diverse driving styles and that policies trained with PeMN demonstrate better generalization than traditional MARL methods.","PeriodicalId":55017,"journal":{"name":"IEEE Systems Journal","volume":"19 1","pages":"317-326"},"PeriodicalIF":4.0,"publicationDate":"2025-02-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143645182","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Balancing these factors is a key challenge for modern green data centers. In this research, we propose a monitoring, visualization, and management system for green data centers (MVMS-GDC). Our comprehensive automated platform includes “monitoring system” and “rules and policy management” modules. The “monitoring system” gathers and visualizes time series data from all resources of a green data center, tracking essential metrics and measurements. It audits green energy, microgrid, climate conditions, workloads, hardware, CPU and memory usage, cluster component health, computing node activities, and network health and quality metrics. The “rules and policy management” module defines and enforces policies to balance resources, ensuring a reliable, sustainable, scalable, and efficient computing environment. We implemented, tested, and evaluated the MVMS-GDC system using green energy at the Zephyr data center located at the GLEAMM site. Our results demonstrate at least a 4.9% improvement in performance, at least a 4% increase in energy efficiency, and a reduction of at least 4% in job losses. The MVMS-GDC system also enhances scalability by employing a policy machine for each compute node, which automates power state control (<sc>on</small>, <sc>off</small>, or hibernation) based on monitoring observations. This automated approach ensures efficient and dynamic scaling, making MVMS-GDC suitable for large and highly distributed data centers. Overall, MVMS-GDC provides a robust solution for balancing energy availability and computational needs, optimizing performance, and maintaining energy efficiency in green data centers.","PeriodicalId":55017,"journal":{"name":"IEEE Systems Journal","volume":"19 1","pages":"119-129"},"PeriodicalIF":4.0,"publicationDate":"2025-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143645229","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hence, robustness against disturbances in affine formation control has been a subject remaining to be determined. To address this problem, a continuous robust controller is introduced in this study, leveraging the robust integral of the sign of the error (RISE) approach, aiming to suppress external disturbances while ensuring efficient convergence speed of the system under various collective formation maneuvers determined by the leader. The controller is designed to handle two types of disturbance models: one involving general disturbances and the other considering time-delay disturbances. It consists of formation tracking terms based on stress matrices and graph theory, as well as disturbance suppression terms utilizing RISE. Sufficient conditions for the stability of affine formations under both types of disturbances are derived. By designing a Lyapunov function that integrates a class-P function, the exponential stability of the closed-loop system is rigorously demonstrated. Finally, simulation results are provided to verify the performance and effectiveness of the proposed control strategy.","PeriodicalId":55017,"journal":{"name":"IEEE Systems Journal","volume":"19 1","pages":"142-151"},"PeriodicalIF":4.0,"publicationDate":"2025-01-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143637865","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the challenge lies in distinguishing between short-circuit faults and system disturbances, e.g., load encroachment, power swing, out-of-step condition, and voltage instability, which can mimic fault conditions and lead to improper relay operation. To address this issue, this article presents a new local protection method by employing three innovative indices: the out-of-step detection index, the positive-sequence impedance angle (PSIA) index, and the superimposed PSIA index. These indices are derived from theoretical principles and are tailored to effectively discriminate between faults and system disturbances. As a major novelty, the determination of indices threshold values is extracted based on the theoretical relationships and further validated through comprehensive static and dynamic analyses. The algorithm's effectiveness is evaluated under various stressed conditions through multiple simulations, showing its ability to distinguish between stressed conditions and short-circuit faults, even in the presence of inverter-based resources. This leads to enhanced power system reliability and security. The proposed method is also cost-effective as it is implemented in the local distance relay, eliminating the need for synchrophasor devices and communication infrastructure.","PeriodicalId":55017,"journal":{"name":"IEEE Systems Journal","volume":"19 1","pages":"270-281"},"PeriodicalIF":4.0,"publicationDate":"2025-01-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143645231","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the SQSM scheme attains a high spectral efficiency and good performance but suffers from a high computational complexity with mMIMO systems. In this article, we propose an efficient low-complexity detection framework for the SQSM scheme. Sparsity detection is amalgamated in this article with minimum mean-square error (MMSE) detector by decoupling the detection of the real and imaginary vector streams. Unfortunately, the MMSE-based detector has a matrix inversion which incurs a high computational complexity. Therefore, we employed several iterative methods; i.e., conjugate gradient and Gauss–Seidel, to avoid the exact matrix inversion, and hence, the computational complexity is significantly reduced. Moreover, the proposed framework can host other iterative methods such as the JA, successive over relaxation, accelerated over relaxation, Neumann series, Newton iteration, two-parameter over relaxation, and Richardson methods. The proposed detection framework attains a significant complexity reduction with a small or insignificant deterioration in the performance.","PeriodicalId":55017,"journal":{"name":"IEEE Systems Journal","volume":"19 1","pages":"32-42"},"PeriodicalIF":4.0,"publicationDate":"2025-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143637909","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
