In modern power systems, the integration of uncertain and sporadic renewable sources, along with uncertainties in load disturbances and inertia, causes rapid power imbalances. This power imbalance, combined with delays in the communication channel and system uncertainties, led to significant frequency deviations in the power system. These deviations affect the other areas and lead to instability in the power system. PID controllers have a solid foundation and are relatively easy to implement; however, they may not fully address the dynamic needs of today’s power grids. Exploring advanced control strategies could enhance their effectiveness and better accommodate the complexities of modern power systems. In response, this paper introduces the Tilt Multistage PID controller with filter (TMSPIDF), designed explicitly for frequency regulation in renewable-integrated power systems. The controller combines the merits of multistage, tilt, and PID controllers within a single controller framework. This controller aims to handle uncertainties associated with power systems more effectively and precisely across various operating scenarios. The performance of the proposed TMSPIDF controller relies on optimal tuning, where the controller's parameters are fine-tuned using the Electric Eel Foraging Optimization (EEO) algorithm. In tests conducted with up to 40 % renewable penetration, the TMSPIDF controller reduced frequency error by 62 % and 39 % and settling times by 75 % and 40 % compared to TPIDF and PIDF controllers. Moreover, the proposed controller demonstrates superiority over TPIDF and PIDF controllers in the face of parametric and system uncertainties.

在现代电力系统中，不确定性和偶发性可再生能源的集成，加上负荷扰动和惯性的不确定性，导致电力快速失衡。这种功率不平衡，再加上通信信道的延迟和系统的不确定性，导致电力系统出现明显的频率偏差。这些偏差影响到其他区域，导致电力系统不稳定。PID控制器基础扎实，相对容易实现；然而，它们可能无法完全满足当今电网的动态需求。探索先进的控制策略可以提高其有效性，更好地适应现代电力系统的复杂性。为此，本文介绍了专为可再生能源集成电力系统的频率调节而设计的带滤波器的倾斜多级PID控制器（TMSPIDF）。该控制器在单个控制器框架内结合了多级、倾斜和PID控制器的优点。该控制器旨在更有效、更精确地处理与电力系统相关的各种运行场景的不确定性。所提出的TMSPIDF控制器的性能依赖于最优调谐，其中控制器的参数使用电鳗觅食优化（EEO）算法进行微调。在可再生渗透率高达40%的测试中，与TPIDF和PIDF控制器相比，TMSPIDF控制器的频率误差分别减少了62%和39%，沉降时间分别减少了75%和40%。此外，在参数不确定性和系统不确定性面前，所提出的控制器比TPIDF和PIDF控制器具有优越性。

The shift from hazardous fossil fuels to renewable energy has resulted in reduced inertia and poor frequency control within electrical power systems eliciting instability and exposure to system wide blackouts. Energy storage systems (ESS) have been proposed as a compelling solution for improved frequency stability in a reduced inertia power system. The adoption of different ESS types contributing to frequency support presents a control challenge. This paper proposes and utilizes Tribrid Energy Storage System (TESS) with controllers contributing to a specific frequency response stage referred to as stage-specific control. The TESS consisted of a Supercapacitor Energy System (SCES) contributing to the inertia response stage, an Electrical Vehicle (EV) contributing to the supplementary control loop, and a Battery Energy Storage System (BESS) contributing to the inertia and supplementary control loop. The power system evaluation model design was based on a Malaysia-Thailand interconnected system, considering a monopolar HVDC tie line. The simulation focused on the effects of the TESSs in Malaysia’s region and the propagating effect in Thailand’s region. Six cases were assessed with different types of loads, RE power mix, and inertia levels. The system demonstrated effectiveness in reducing frequency Nadir, oscillation, and settling time, while in Thailand, the improvement was to the oscillatory component of the frequency response. Standard deviation calculation illustrates an average improvement of 80.13 %, 71.80 %, and 53.72 % in Malaysia’s frequency, tie line power, and Thailand’s frequency, respectively. Sensitivity analysis demonstrated the effectiveness of the system in different power plants. The research indicates the importance of the utilization and configuration of ESS controls in contributing to frequency support.

从危险的化石燃料向可再生能源的转变导致电力系统的惯性减少和频率控制不良，从而导致不稳定和全系统停电。储能系统（ESS）已被提出作为一个引人注目的解决方案，以提高频率稳定性在一个减少惯性电力系统。采用不同类型的ESS有助于提供频率支持，这对控制提出了挑战。本文提出并利用具有特定频率响应级的控制器的混合储能系统（TESS），称为特定级控制。该系统由超级电容器能量系统（SCES）构成惯性响应阶段，电动汽车（EV）构成补充控制回路，电池储能系统（BESS）构成惯性和补充控制回路。电力系统评估模型设计基于马来西亚-泰国互联系统，考虑单极高压直流并线。模拟的重点是tess在马来西亚地区的影响和泰国地区的传播效应。评估了6例不同类型负载、可再生能源功率组合和惯性水平的病例。该系统在减少频率最低点、振荡和沉降时间方面表现出有效性，而在泰国，改善的是频率响应的振荡分量。标准偏差计算表明，马来西亚的频率、线路功率和泰国的频率平均分别提高了80.13%、71.80%和53.72%。灵敏度分析证明了该系统在不同电厂的有效性。研究表明，ESS控制的使用和配置对频率支持的重要性。

This paper proposes designing, simulating, and hardware implementing a NARMA-L2 neural network controller for the boost half-bridge rectifier with a high power factor. The neural controller consists of two neural networks that can be reorganized to obtain the controller after being trained. Unlike traditional linear controllers, this scheme enables the handling of nonlinearities. The system model is presented with the respective control scheme. The plant is first identified with the NARMA-L2 model, and then the neural network structure is reorganized to have the controller. An experimental design is carried out for the design of the NARMA-L2 controller considering the number of neurons in the hidden layer and the number of delays (used for the signals). The mean squared error is utilized as a performance metric to determine the suitable configuration to implement the NARMA-L2 system. The controller operation is first tested in simulation to verify its correct operation, calculating the power factor and harmonic distortion. Then the controller hardware is implemented in the DSP TMS320F28335 (Texas Instruments), performing different experiments and taking the measurements to verify the correct operation of the NARMA-L2 controller. The outcomes show that the control system functions adequately in simulation and hardware implementation. Finally, this work verifies the possibility of implementing the NARMA-L2 for controlling a boost half-bridge rectifier with power factor correction.

The climate crisis and global warming have created an urgent need for the scalable adoption of affordable and clean energy sources to achieve net-zero carbon emissions by 2050. Decarbonization of global industries is critical to achieving the targets of the Paris Agreement and the United Nations Sustainable Development Goals (especially Goals 7 and 13). Green hydrogen is becoming a key solution in the transition to renewable energy and the decarbonization with low-carbon energy options. This review presents an overview of the status and trends of hydrogen production, storage, transportation, and application, as well as key research areas with a forward-looking perspective to 2050. It explores the key challenges, such as limited infrastructure, high production costs, and heavy energy demands. The study also identifies the drivers and barriers influencing hydrogen adoption across utility-scale electricity generation, heating, and niche markets. Key actions of governments in these pillar areas are necessary to accelerate hydrogen deployment through strategic investments and a policy framework to reduce technological costs and drive innovation. Transformative innovation in power generation, transportation, industrial processes, and infrastructure will be essential to achieving deep decarbonization. In addition, progress in digitalization, automation, data-driven decision-making, recycling incentives, and circular economies are essential to a social transformation and a global transition toward sustainability. Emerging hydrogen markets are also playing an increasingly dominant role in economic and human development, particularly in low- and middle-income countries, as the world works to transition to the use of renewable hydrogen.

气候危机和全球变暖迫切需要大规模采用负担得起的清洁能源，以便到2050年实现净零碳排放。全球工业脱碳对于实现《巴黎协定》和联合国可持续发展目标（特别是目标7和13）至关重要。绿色氢正在成为向可再生能源过渡和以低碳能源选择脱碳的关键解决方案。本文综述了氢的生产、储存、运输和应用的现状和趋势，以及到2050年的重点研究领域。它探讨了关键的挑战，如有限的基础设施、高生产成本和巨大的能源需求。该研究还确定了影响公用事业规模发电、供暖和利基市场采用氢的驱动因素和障碍。政府必须在这些支柱领域采取关键行动，通过战略投资和政策框架来降低技术成本和推动创新，加速氢的部署。发电、交通、工业流程和基础设施方面的变革性创新对于实现深度脱碳至关重要。此外，数字化、自动化、数据驱动决策、回收激励和循环经济方面的进展对于社会转型和全球向可持续发展过渡至关重要。随着世界努力向使用可再生氢过渡，新兴氢市场在经济和人类发展中也发挥着越来越重要的作用，特别是在低收入和中等收入国家。

Recently, energy storage units (ESUs) have become indispensable energy sources in the power supply market. So, the roll-out of an ESU necessitates autonomous energy control systems that can use real-time data at a high energy distribution level in the smart microgrids (SMGs). This aims to decrease users' energy costs and address the uncertainty in the stochastic behavior of these microgrids. This paper proposes a central energy controller using the deep deterministic policy gradient (DDPG) strategy as an artificial intelligence technique to control the ESU energy distribution between two adjacent SMGs. Using a central controller eliminates the need for sub-controllers, which increases the system's complexity and thus degrades its efficiency. The proposed control strategy's superior efficiency in decreasing the energy cost is confirmed by applying the proposed strategy to the training and testing data and validated by comparing the results with those of the traditional artificial bee colony (ABC) algorithm. The simulation results illustrate that the introduced control strategy achieves an error rate less than 2 % compared with the conventional method (ABC). In addition, the proposed system structure eliminates the need to install an additional, expensive energy storage unit in the second SMG.

近年来，储能单元（esu）已成为供电市场不可或缺的能源。因此，ESU的推出需要自主能源控制系统，该系统可以在智能微电网（smg）的高能量分配水平上使用实时数据。这旨在降低用户的能源成本，并解决这些微电网随机行为的不确定性。本文提出了一种利用深度确定性策略梯度（deep deterministic policy gradient， DDPG）策略作为人工智能技术的中央能量控制器来控制两个相邻smg之间的ESU能量分布。使用中央控制器消除了对子控制器的需求，子控制器增加了系统的复杂性，从而降低了系统的效率。将该控制策略应用于训练和测试数据，并与传统人工蜂群（ABC）算法的结果进行比较，验证了该控制策略在降低能量成本方面的优越性。仿真结果表明，与传统控制方法（ABC）相比，所提出的控制策略的错误率小于2%。此外，所提出的系统结构不需要在第二个SMG中安装额外的、昂贵的储能单元。

Over the last few decades, remarkable progress in achieving stable power efficiency of Perovskite Solar Cells (PSCs) has made researchers recognize their substantial potential in mitigating the global energy crisis. In this paper, the currently thriving research trends of perovskite solar cells are reviewed from the perspective of both environmental impacts and cost effectiveness. After a brief review of the main design challenges rising from the instability and toxicity of PSCs, a performance analysis of the notably efficient and cost-effective PSC designs in recent research literature is conducted. The continuous stability improvement of PSCs over the years is discussed, detailing crystal structure modification, film quality improvement, encapsulation, band alignment, strain engineering, and other defect reduction strategies. The environmental considerations for PSC design are covered next, encompassing toxicity reduction strategies and lifecycle assessments for assessing important environmental and energy impact parameters of energy payback time (EPBT) and greenhouse gas (GHG) emissions. The feasibility of commercializing PSCs is also assessed by the technoeconomic analyses in literature that compare minimum sustainable price (MSP) and levelized cost of energy (LCOE) of PSCs to that of other technologies. Finally, the observations are used to identify future prospects and emerging trends of PSC research. It can be observed that perovskite solar cells, especially tandem cells reaching record efficiency of 34.6% exceeding the Shockley-Queisser efficiency limit, have become prime candidates for developing sustainable energy solutions on a large scale.

在过去的几十年里，钙钛矿太阳能电池（PSCs）在实现稳定的功率效率方面取得了显著的进展，使研究人员认识到它们在缓解全球能源危机方面的巨大潜力。本文从环境影响和成本效益两方面综述了目前钙钛矿太阳能电池的研究趋势。在简要回顾了PSC的不稳定性和毒性所带来的主要设计挑战之后，对最近研究文献中高效且具有成本效益的PSC设计进行了性能分析。讨论了多年来PSCs稳定性的不断提高，详细介绍了晶体结构修改、薄膜质量改善、封装、能带对准、应变工程和其他减少缺陷的策略。接下来介绍了PSC设计的环境考虑因素，包括毒性降低策略和生命周期评估，用于评估能源回收期（EPBT）和温室气体（GHG）排放等重要环境和能源影响参数。文献中的技术经济分析也对PSCs商业化的可行性进行了评估，这些分析将PSCs的最低可持续价格（MSP）和平准化能源成本（LCOE）与其他技术进行了比较。最后，利用观察结果确定PSC研究的未来前景和新兴趋势。可以观察到，钙钛矿太阳能电池，特别是串联电池达到创纪录的34.6%，超过了Shockley-Queisser效率极限，已成为大规模开发可持续能源解决方案的主要候选者。

Building Integrated Photovoltaics (BIPV) offers an innovative approach to achieving net-zero energy buildings by seamlessly integrating solar energy systems into architectural designs. However, the widespread adoption of BIPV systems is often hindered by concerns over high initial costs and uncertain economic returns. This study conducts a comprehensive techno-economic assessment of BIPV systems in Scotland to evaluate their energy generation potential, cost-effectiveness, and financial viability across different urban locations. A 1 kWp grid-connected BIPV system was simulated using PVsyst software for four distinct urban areas in Scotland—Aberdeen, Glasgow, Edinburgh, and Portree. The analysis considered 10 different tilt angles (0° to 90° in 10° increments) and 8 azimuth angles (-180° to 180° in 45° increments) to cover a wide range of building orientations. Key performance indicators, including Annual Energy Generation (AEG), Levelized Cost of Energy (LCOE), and Payback Period (PP), were evaluated to determine the feasibility of BIPV systems in these locations. Additionally, MATLAB was used solely to generate 3D graphs for clearer visualisation and more effective analysis, utilising the data obtained from PVsyst simulations.

The findings reveal that Aberdeen provides the most favourable conditions for BIPV deployment, achieving an AEG of 1167 kWh/year, an LCOE of 0.0606 GBP/kWh, and a PP of 7.2 years at an optimal orientation of 0° azimuth and 40° tilt. Conversely, Portree exhibited the least favourable outcomes, with an AEG of 312 kWh/year, an LCOE of 0.2268 GBP/kWh, and a PP of 17.4 years at 180° azimuth and 90° tilt. These results offer valuable insights for policymakers, solar developers, and building designers, helping optimise Scotland's BIPV deployment strategies for enhanced economic and environmental benefits.

建筑集成光伏（BIPV）通过将太阳能系统无缝集成到建筑设计中，为实现净零能耗建筑提供了一种创新的方法。然而，由于对初始成本高和经济回报不确定的担忧，BIPV系统的广泛采用往往受到阻碍。本研究对苏格兰BIPV系统进行了全面的技术经济评估，以评估其在不同城市地区的发电潜力、成本效益和财务可行性。使用PVsyst软件对苏格兰阿伯丁、格拉斯哥、爱丁堡和波特里四个不同的城市地区的1千瓦时并网BIPV系统进行了模拟。分析考虑了10个不同的倾斜角（0°到90°，增量为10°）和8个方位角（-180°到180°，增量为45°），以覆盖广泛的建筑方向。评估了年度发电量（AEG）、能源平净成本（LCOE）和投资回收期（PP）等关键绩效指标，以确定BIPV系统在这些地区的可行性。此外，MATLAB仅用于生成3D图形，以更清晰的可视化和更有效的分析，利用从PVsyst模拟中获得的数据。研究结果表明，阿伯丁为BIPV的部署提供了最有利的条件，在0°方位角和40°倾角的最佳方位下，AEG为1167 kWh/年，LCOE为0.0606 GBP/kWh， PP为7.2年。相反，Portree表现出最不利的结果，AEG为312千瓦时/年，LCOE为0.2268英镑/千瓦时，180°方位角和90°倾角的PP为17.4年。这些结果为政策制定者、太阳能开发商和建筑设计师提供了有价值的见解，有助于优化苏格兰的BIPV部署策略，以提高经济和环境效益。

The development of a high-performance antenna for digital television receivers was carried out by integrating a frequency selective surface (FSS) technique with electromagnetic bandgap (EBG) metamaterial structures in the form of mushroom-type cavities. The base antenna used in this study is a planar dipole, which inherently exhibits narrow bandwidth and low gain, rendering it insufficient for digital television signal reception. To address this limitation, a band-notched technique was first applied by etching slots into the antenna structure to broaden its impedance bandwidth across the required frequency range. However, the resulting antenna still exhibited low gain performance. To improve gain, a mushroom-type EBG structure was designed and implemented as a reflector positioned behind the antenna. This configuration resulted in an average gain enhancement of approximately 3 dBi. However, we observed a decrease in the bandwidth, which was insufficient to cover the required frequency range for digital TV reception. To overcome this issue, a frequency selective surface (FSS) structure was introduced and designed to resonate at the desired frequency range, aiming to enhance the bandwidth. When the FSS was put in front of the antenna, the range of frequencies it could effectively use grew a lot, completely covering the needed frequency range while still benefiting from the gain boost from the EBG reflector. As a result, the proposed antenna achieved a gain ranging from 7.2 to 8.03 dBi and an impedance bandwidth spanning 462–951 MHz.

将频率选择表面（FSS）技术与电磁带隙（EBG）超材料结构相结合，开发了一种高性能的数字电视接收机天线。本研究使用的基天线为平面偶极子天线，固有的带宽窄、增益低，不足以接收数字电视信号。为了解决这一限制，首先应用了一种带缺口技术，通过在天线结构中蚀刻槽来在所需的频率范围内拓宽其阻抗带宽。然而，所得到的天线仍然表现出低增益性能。为了提高增益，设计并实现了一种蘑菇型EBG结构，作为天线后面的反射器。这种配置导致平均增益增强约3 dBi。然而，我们观察到带宽有所下降，不足以覆盖数字电视接收所需的频率范围。为了克服这个问题，引入了频率选择表面（FSS）结构，并设计了在所需频率范围内谐振的结构，旨在提高带宽。当FSS被放置在天线前面时，它可以有效使用的频率范围增加了很多，完全覆盖了所需的频率范围，同时仍然受益于EBG反射器的增益提升。结果表明，该天线的增益范围为7.2 ~ 8.03 dBi，阻抗带宽为462 ~ 951 MHz。

This article presents a novel 24-pulse rectifier with three new auxiliary circuits at the DC side to address the harmonic mitigation in input line currents, specifically for low-voltage and high-current applications. The proposed topology combines a double-star configuration with an integrated tapped interphase reactor (ITIPR) and its associated auxiliary circuits. These circuits reinject triangular currents from the ITIPR, improving the output voltage and current profiles while increasing the input current steps. The ITIPR and the auxiliary injection circuits transform the six-pulse rectifier into a 24-pulse rectifier, quadrupling the pulse count. The ITIPR’s tap ratios are optimized to minimize the total harmonic distortion (THD) of the input line current, achieving 7.71 % under optimal conditions. Unlike conventional 24-pulse rectifiers, the proposed design avoids additional input side transformers, making it compact, efficient, and cost-effective. It also features a simpler design with lower losses and fewer components. A 3 kW simulation prototype was developed and analyzed in MATLAB to validate the theoretical analysis.
