While hydrogen energy storage coupled with water electrolysis and fuel cells offers a promising solution to balance supply-demand fluctuations. Existing control strategies for multi-energy systems often rely on open-loop frameworks that lack real-time adaptability. As a result, sub-optimal PV utilization and grid unstable may happens. This paper proposes an innovative closed-loop model predictive control (MPC) scheme enhanced by hybrid artificial intelligence to maximize PV intake and minimize grid-user power exchange in a PV-hydrogen-microgrid system. The MPC mechanism uniquely incorporates feedback correction and a hybrid prediction algorithm (EMD-KPCA-LSTM) to address PV uncertainty: empirical mode decomposition (EMD) extracts intrinsic mode functions from environmental and PV data, kernel principal component analysis (KPCA) reduces feature dimensions, and long short-term memory (LSTM) networks enable high-accuracy PV power forecasting. Iterative genetic algorithm (GA) optimization generates optimal control sequences for 24-h operation. Case studies using real-world data from China demonstrate that the proposed scheme reduces grid interaction by 42.6% and increases PV utilization by 13.7% in average compared to baseline methods. Key innovations include (1) a feedback-corrected MPC framework for dynamic adaptation to PV and load fluctuations, (2) the EMD-KPCA-LSTM hybrid model enhancing prediction accuracy, and (3) an SSM constrained optimization strategy specifically targeting PV intake maximization rather than conventional cost minimization. This work provides a scalable solution for renewable-rich grids transitioning to low-carbon multi-energy systems.</p>","PeriodicalId":55000,"journal":{"name":"IET Renewable Power Generation","volume":"19 1","pages":""},"PeriodicalIF":2.6,"publicationDate":"2025-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1049/rpg2.70069","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144536971","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 evaluates the economic benefits and impact on inverter lifespan of extended Q provision, developing a pricing model that considers both dispatch and reserve costs. The study examines the provision of Q outside the technical connection rules of a utility-scale PV power plant in the transmission grid. Utilizing a detailed simulation model of a real extra high voltage PV park with 350 MW installed power, cost components are presented, valuation approaches formulated, and their application in the transmission grid examined. The basic valuation approach considers both plant-specific and external costs, focusing on active power losses and inverter wear. The analysis shows that relative losses (MWh/Mvar) in the park vary due to dispatch patterns, representing the highest cost sensitivity. Our results underscore the importance of these factors in determining the Q price. The findings indicate that additional Q can be provided without structural changes to the inverters, but economic viability depends on appropriate compensation mechanisms.

To consider the uncertainty of renewable energy sources in the MEM, different scenarios for solar radiation and wind speed are taken into account in the proposed framework.

The results confirm that coordinated charging strategy for EVs and using vehicle-to-grid technology in peak hours have the potential to decrease operational cost and emissions of the MEM by about 1.05% and more than 0.76%, respectively.

However, existing high-accuracy algorithms, especially those based on neural networks, frequently face challenges such as poor interpretability and decreased accuracy in noisy environments. To address these issues, this paper proposes an interpretable fault detection method for PMSMs based on sparse representation theory, termed IAIUNet-SRC. The proposed low-dimensional over-relaxation ADMM algorithm (LOADMM) effectively reduces computational complexity by incorporating over-relaxation techniques and matrix inversion lemmas, thereby avoiding direct matrix inversion operations and enhancing convergence efficiency. Building upon LOADMM, the iterative algorithm-induced deep-unfolding network (IAIUNet) translates the iterative process of LOADMM into a layer-wise neural network structure, embedding learnable parameters to adaptively optimise performance. This design inherently preserves the interpretability of the optimisation process. Experimental results demonstrate that under noisy conditions, IAIUNet-SRC achieves a fault detection accuracy of 98.87%, representing a 2.51% improvement over the baseline method ADMM-SRC, while reducing computation time by 80%.</p>","PeriodicalId":55000,"journal":{"name":"IET Renewable Power Generation","volume":"19 1","pages":""},"PeriodicalIF":2.6,"publicationDate":"2025-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1049/rpg2.70062","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144515111","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}

Nevertheless, the comprehensive transient operation analysis under large disturbances remains a critical issue, owing to the challenges in the analysis and characterisation of high-order nonlinear VSC systems. In this regard, a coupling-factor-based nonlinear decoupling (CFND) method is proposed in this paper. Firstly, by evaluating the correlation degree between state variables with coupling factors, the original nonlinear high-order system can be divided into multiple decoupled first- or second-order cubic modes, which can facilitate the transient stability analysis. Secondly, with the proposed CFND method, the full-order large-signal model of LCL-filtered grid-connected VSCs is created to analyse the transient stability under grid fault conditions. It is revealed that increasing phase-locked loop (PLL) bandwidth and decreasing current loop bandwidth are unfavourable to the transient stability. Besides, decreasing the active current reference or increasing the reactive current reference is beneficial for transient stability during the low voltage ride-through (LVRT) process. Finally, the effectiveness of the stability analysis results is verified through hardware-in-loop (HIL) experiments.</p>","PeriodicalId":55000,"journal":{"name":"IET Renewable Power Generation","volume":"19 1","pages":""},"PeriodicalIF":2.6,"publicationDate":"2025-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1049/rpg2.70090","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144473180","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}

Recent publications have shown the general feasibility of grid-forming WPPs for black-starting HVDC links, but focus on single aspects of the energization or rely on simplified wind farm, converter, or control models. Until now, important aspects such as the influence of converter or WPP design, as well as a derivation of the requirements posed on the different components for each step of the black-start have not yet been analysed.

It reduces bottlenecks in the power grid and also reduces the dependency from hydro and thermal power plants for the optimal power flow management. Worldwide, at least a 20% penetration of distributed RESs is considered necessary over the next decade. The intermittent nature of RESs results in systems with delays in dynamics, non-linearties, power quality issues, etc. Over the last few decades, power quality issues have become increasingly important in grid-connected renewable energy systems. In addition to the intermittent nature of RESs, the widespread use of non-linear electronic devices further complicates the problem. With the advent of power electronic converters with robust control technology, RESs can be massively connected to the grid for power supply or used as stand-alone systems in remote location. Using more efficient control strategies not only improves the performance of these systems, but also improves power quality during generation, distribution, and consumption on the consumer side of utility systems.&lt;/p&gt;&lt;p&gt;The ever-declining fossil fuel resources and the increasing concerns for the environment have led to intensive research into the generation and use of RESs. Innovative processes for generating and using renewable energy are becoming increasingly attractive. Many applications integrate renewable energy sources into existing utility grids, micro-grids, or isolated loads. Power electronics and drives are one of the most important components of modern renewable energy system applications.
