This comprehensive review systematically categorizes, analyzes, and benchmarks traditional, intelligent, and hybrid MPPT algorithms under dynamic and nonideal operating conditions, including partial shading, temperature fluctuations, rapid irradiance transients, and real-world stressors such as panel soiling and module aging. Conventional methods like Perturb and Observe (P&amp;O) and incremental conductance (INC), while simple, exhibit significant limitations including steady-state oscillations and susceptibility to local maxima under shading. Intelligent techniques—encompassing fuzzy logic control, artificial neural networks, and metaheuristic algorithms like particle swarm optimization (PSO) and grey wolf optimizer (GWO)—demonstrate superior accuracy, adaptability, and global search capabilities. Hybrid strategies, which synergize global exploration with local refinement, consistently achieve tracking efficiencies exceeding 99% under the specific partial shading patterns and environmental conditions reported in each study. Notably, advanced deep reinforcement learning (DRL) frameworks, particularly memory-augmented architectures such as PPO-LSTM, achieve exceptional adaptability with &gt; 99.3% accuracy in complex multipeak environments. A critical contribution of this review is the systematic identification of four key limitations in standard PV modeling for MPPT evaluation: ill-posed parameter identification, model uncertainty from manufacturing tolerances and aging, inaccurate temperature effects, and the trade-offs of multidiode models. Experimental validations confirm the performance supremacy of intelligent and hybrid methods, though challenges in computational demand and hardware implementation persist. This study consolidates state-of-the-art advancements, providing a foundational roadmap for future research focused on hardware acceleration, uncertainty-aware DRL, multiagent coordination, and lifelong learning to enhance real-time applicability, grid stability, and long-term energy yield in next-generation resilient PV systems.</p>","PeriodicalId":51293,"journal":{"name":"International Transactions on Electrical Energy Systems","volume":"2026 1","pages":""},"PeriodicalIF":2.6,"publicationDate":"2026-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1155/etep/6465506","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149047968","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The primary innovations consist of a unique Dependency Reduction Index (DRI) objective function aimed at enhancing the microgrid’s self-sufficiency. The optimization problem is tackled using an Improved Newton–Raphson Method (INRM). The adaptive sigma point approach is employed to represent uncertainties associated with load, EV, and renewable energy sources. The results demonstrate that incorporating the DRI objective significantly enhances the energy independence of the microgrid, resulting in lower operational and emission costs. In summary, the paper claims that the proposed optimization framework successfully balances economic, environmental, and resilience goals, offering a practical and superior solution for modern microgrid operations. The implementation of the DRI objective led to remarkable enhancements in microgrid operational autonomy, achieving a 5.69% reduction in operational costs and a 4.48% decrease in emissions. This illustrates that dependency-aware optimization fundamentally transforms resource allocation strategies, reshaping the microgrid operational model into one that relies less on the grid through the strategic coordination of charging stations and storage systems, fostering a scenario where improved self-sufficiency and economic efficiency support each other rather than conflict. The coordination of charging stations with the microgrid, guided by the DRI, resulted in a 12.78% reduction in DR costs, thanks to the sophisticated management of battery storage, EV, and EB charging stations within a hierarchical storage framework that operates synergistically across various case studies.</p>","PeriodicalId":51293,"journal":{"name":"International Transactions on Electrical Energy Systems","volume":"2026 1","pages":""},"PeriodicalIF":2.6,"publicationDate":"2026-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1155/etep/3535070","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149047889","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper proposes a hardware-assisted decoupling method using magnetically coupled reactors (MCRs) to physically interrupt the coupling path. The MCR achieves decoupling through two synergistic mechanisms: additional damping from mutual inductance suppresses current change rates and transient energy buffering from auxiliary winding LC circuits absorbs power fluctuations during transients. A comprehensive mathematical model quantifies the relationship between additional damping and system parameters, and a systematic parameter design methodology is developed. Simulation results on a 10-MVA DSSC system demonstrate that the proposed method reduces the coupling coefficient from 0.09 to 0.04 Mvar/MW, achieving 55% decoupling improvement. The DC bus voltage fluctuation decreases by 44%, regulation time is shortened by 25%, and the power factor adjustment range expands by 50%.

The approach relies on a set of six descriptors including phase-current ratios, zero-sequence measures, and a synthetic impedance deviation indicator ∆<i>Z</i>. Additionally, we used the zero-to-positive-sequence current ratio <i>I</i><sub>0</sub>/<i>I</i><sub>1</sub> to ensure robust fault classification in the presence of distributed generation (DG) while maintaining low computational overhead suitable for intelligent electronic devices. We adopted a cross-domain validation protocol: Classifiers are trained on synthetic data generated via MATLAB/Simulink fault scenarios and then evaluated using real disturbance records extracted from digital protection relays in COMTRADE format within the Moroccan MV grid. Our evaluation compared radial basis function neural networks (RBFNN) against random forest (RF) and gradient boosting (GB) models. Among these, RF shows the most consistent generalization, achieving 98.5% accuracy on the available field dataset. The investigation further validates the system’s resilience in active networks, ensuring that the proposed feature set maintains sensitivity where traditional relays fail due to DG infeed and confirming the RF model’s suitability for bidirectional fault-current contributions.

In contrast to currently available methods that consider aggregated system behavior, this paper clearly shows how individual DERs, i.e., residential solar panels, commercial batteries, and wind turbines, react to VPP coordination cues using IoT-based monitoring and control. The framework shows that the basic performance between deployment scenarios is that the urban test settings with HVAC-dominated loads (45%) and rooftop solar (60%) realize a cost reduction of 18.4 percent over fiber/4G networking with subsecond delays; the rural deployment settings with agricultural loads (60 percent) and ground-mounted wind farms (45 percent) over LoRaWAN result in a cost reduction of 15.7 percent in spite of their delayed communication delays of 2 to 5 s; suburban deployment settings with balanced residential and commercial loads (40% residential, 30% commercial, 30% HVAC) and a hybrid DER mix (50% rooftop PV, 25% wind, 25% battery storage) over fiber/LTE hybrid networks achieve a cost reduction of 17.2 percent despite the extended peak window spanning 12–8 PM. The effectiveness of the framework is confirmed by the detailed analysis of the individual DER dispatch patterns, i.e., the IoT sensor networks performance (1 min sampling in smart meters, 30 Hz in PMUs) and the performance of communication protocols (fiber, 4G/5G, LoRaWAN) among 10,000 DERs. Findings indicate a 23.7 percent enhancement in the integration of renewable energy and a 31.2 percent decrease in peak loads and clearly indicate how the composition of the load, strategies of DER placement, and the capabilities of the IoT infrastructure influence the coordination effectiveness.
