一种新型的部分遮挡和非匹配条件下最大功率点跟踪光伏子模块级功率平衡拓扑结构 Article

Mustafa GOKDAG,Mehmet AKBABA

《信息与电子工程前沿（英文）》 2016年第17卷第12期页码 1388-1396 doi: 10.1631/FITEE.1500322

摘要：部分遮挡和串联模块（或子模块）的非匹配条件可在整个光伏系统中导致功率曲线非凸且出现多个局部极值和峰值功率下降的现象。通过功率传输，可将各子模块的工作电压拉平；这样的功率收集操作可生成凸功率曲线，提升光伏系统的峰值功率。本文所述拓扑结构受益于开关电容（Switched capacitor, SC）转换器的概念，是一种子模块级功率平衡概念的具体应用。与现有研究成果相比，其创新点包含无遮挡时停止开关操作、串联线路级可拓展性以及减少功率电子元件使用量。功率电子元件使用量的减少是通过两个子模块共享一个SC转换器的方式实现的，这也能带来降低功率器件能量损耗、降低成本和电路体积的优势。

基于可靠特征点分配算法的鲁棒性跟踪框架 Article

Rong-feng ZHANG, Ting DENG, Gui-hong WANG, Jing-lun SHI, Quan-sheng GUAN

《信息与电子工程前沿（英文）》 2017年第18卷第4期页码 545-558 doi: 10.1631/FITEE.1601464

摘要：视觉跟踪是近年来计算视觉最活跃的研究课题之一，已被广泛应用于许多视觉领域。然而，视觉跟踪技术仍然存在挑战，如目标发生光照变化、遮挡、外观形变等。为克服这些技术困难，本文提出基于小波变换的可靠特征点分配（Reliable point assignment, RPA）算法。通过搜索局部最大小波系数（Local maximal wavelet coefficients, LMWC）的位置，获得可靠特征点。在图像中，具有局部最大小波系数之处，表明该处图像信号发生了较大变化，因此，可靠特征点对图像噪声、光照变化和外观形变等情况都具有鲁棒性。此外，在检测中应用卡尔曼滤波器，以提高处理速度并减少误检率。最后，将所提出的RPA与卡尔曼滤波器集成到跟踪–学习–检测（Tracking–learning–detection, TLD）算法框架中，提高了跟踪精度，且降低了误检率。

A comprehensive simulator for assessing the reliability of a photovoltaic panel peak power tracking system

Nabil KAHOUL,Mourad HOUABES,Ammar NEÇAIBIA

《能源前沿（英文）》 2015年第9卷第2期页码 170-179 doi: 10.1007/s11708-015-0353-y

摘要： When designing a maximum power point tracking (MPPT) algorithm, it is often difficult to correctly predict, before field testing, the behavior of this MPPT under varying solar irradiation on photovoltaic (PV) panels. A solution to this problem is to design a maximum power point trackers simulator of a PV system used to test MPPT algorithms. This simulator must have the same role as the MPPT card of the PV panel and thus will fully emulate the response of a real MPPT card of the PV panel. Therefore, it is a good substitute to help to test the peak power trackers of the PV system in the laboratory. This paper describes a simple peak power trackers simulator of the PV system which has a short response time thus, can be used to test MPPT algorithms under very rapid variation condition. The obtained results and the theoretical operation confirm the reliability and the superior performance of the proposed model.

《能源前沿（英文）》 2015年第9卷第1期页码 43-53 doi: 10.1007/s11708-014-0343-5

摘要： Due to the high interest in renewable energy and diversity of research regarding photovoltaic (PV) array, a great research effort is focusing nowadays on solar power generation and its performance improvement under various weather conditions. In this paper, an integrated framework was proposed, which achieved both maximum power point tracking (MPPT) and minimum ripple signals. The proposed control scheme was based on extremum-seeking (ES) combined with fractional order systems (FOS). This auto-tuning strategy was developed to maximize the PV panel output power through the regulation of the voltage input to the DC/DC converter in order to lead the PV system steady-state to a stable oscillation behavior around the maximum power point (MPP). It is shown that fractional order operators can improve the plant dynamics with respect to time response and disturbance rejection. The effectiveness of the proposed controller scheme is illustrated with simulations using measured solar radiation data.

Novel power capture optimization based sensorless maximum power point tracking strategy and internal

Ali EL YAAKOUBI,Kamal ATTARI,Adel ASSELMAN,Abdelouahed DJEBLI

《能源前沿（英文）》 2019年第13卷第4期页码 742-756 doi: 10.1007/s11708-017-0462-x

摘要： Under the trends to using renewable energy sources as alternatives to the traditional ones, it is important to contribute to the fast growing development of these sources by using powerful soft computing methods. In this context, this paper introduces a novel structure to optimize and control the energy produced from a variable speed wind turbine which is based on a squirrel cage induction generator (SCIG) and connected to the grid. The optimization strategy of the harvested power from the wind is realized by a maximum power point tracking (MPPT) algorithm based on fuzzy logic, and the control strategy of the generator is implemented by means of an internal model (IM) controller. Three IM controllers are incorporated in the vector control technique, as an alternative to the proportional integral (PI) controller, to implement the proposed optimization strategy. The MPPT in conjunction with the IM controller is proposed as an alternative to the traditional tip speed ratio (TSR) technique, to avoid any disturbance such as wind speed measurement and wind turbine (WT) characteristic uncertainties. Based on the simulation results of a six KW-WECS model in Matlab/Simulink, the presented control system topology is reliable and keeps the system operation around the desired response.

摘要： In this paper, based on the analysis of the mathematical model in a common synchronous reference frame of the brushless doubly-fed generator (BDFG), the grid connection strategy and maximum energy extraction control were both analyzed. Besides, the transient simulation of no-load model and generation model of the BDFG have been developed on the MATLAB/Simulink platform. The test results during cutting-in grid confirmed the good dynamic performance of grid synchronization and effective power control approach for the BDFG-based variable speed wind turbines.

在现场可编程门阵列中用于降低泄漏功率的动态电源门控 Research Article

Hadi JAHANIRAD

《信息与电子工程前沿（英文）》 2023年第24卷第4期页码 582-598 doi: 10.1631/FITEE.2200084

摘要：在现代集成电路技术中，泄漏功率几乎相当于动态功率，因此降低泄漏功率可以显著节省能耗。我们提出一种基于静态随机存取存储器（SRAM）的FPGA高效架构，其中每个模块定义了两种模式（活动模式和休眠模式）。在休眠模式下，模块消耗超低泄漏功率。当模块输出对新输入向量的评估时，模块模式由休眠模式动态改变为活动模式。在产生正确的输出后，该模块返回到休眠模式。所提电路设计在活动模式和休眠模式下都降低了泄漏功耗。

THD reduction with reactive power compensation for fuzzy logic DVR based solar PV grid connected system

Akhil GUPTA,Saurabh CHANANA,Tilak THAKUR

《能源前沿（英文）》 2014年第8卷第4期页码 464-479 doi: 10.1007/s11708-014-0307-9

摘要： Dynamic voltage restorer (DVR) is used to protect sensitive loads from voltage disturbances of the distribution generation (DG) system. In this paper, a new control approach for the 200 kW solar photovoltaic grid connected system with perturb and observe maximum power point tracking (MPPT) technique is implemented. Power quality improvement with comparison is conducted during fault with proportional integral (PI) and artificial intelligence-based fuzzy logic controlled DVR. MPPT tracks the actual variable DC link voltage while deriving the maximum power from a photovoltaic array and maintains DC link voltage constant by changing modulation index of the converter. Simulation results during fault show that the fuzzy logic based DVR scheme demonstrates simultaneous exchange of active and reactive power with less total harmonic distortion (THD) present in voltage source converter (VSC) current and grid current with fast tracking of optimum operating point at unity power factor. Standards (IEEE-519/1547), stipulates that the current with THD greater than 5% cannot be injected into the grid by any distributed generation source. Simulation results and validations of MPPT technique and operation of fuzzy logic controlled DVR demonstrate the effectiveness of the proposed control schemes.
