[Program doc] MPPT DL : 0: 太阳能光伏阵列在光照强度不均匀或者处于部分遮阴情形时，它的功率一电压输出特性曲线将出现多峰现象，这种情况下如果继续采用传统的最大功率跟踪法会造成光伏阵列输出功率的降低，从而导致光伏发电系统的效率的降低。本文首先介绍了光伏并网发电的研究背景和意义，分析了国内外的现状和光伏并网发电关键问题的现状，接着对光伏电池的工作原理、等效模型和输出特性三方面进行了作了全面的分析在此基础上，深入研究了热斑效应和部分遮阴条件下光伏电池不同的表现性能然后，本文详细介绍了常用的最大功率跟踪方法的原理、优缺点和适用的场合及存在的一些问题，同时提出了一种适用于部分遮阴条件下的基于电导增量法的全局搜索算法。基于以上研究，本文又设计了实现最大功率跟踪控制的硬件电路，其中包括Boost电路和DSP的外围控制电路。 - It is widespread that there is uneven light intensity, partial shading and other phenomena in various photovoltaic (PV) power generation systems, this phenomenon will not only affect the power output of the PV arrays, but also will cause problems with the safety and stability. The P-U characteristics of PV array will appear multi-peaks in the partial shade condition, making the conventional maximum power point tracking(MPPT) algorithm fail to apply in this case.

[Other] Grid-Connected-PV-System DL : 0: This paper presents a PSCAD/EMTDC model of PV solar panels, the grid connected three phase voltage sourced inverter (VSI) and its controller system. The VSI control is implemented with current control loops. A maximum power point tracking (MPPT) algorithm is implemented to get the maximum output power for any given solar irradiation and temperature. This is integrated with the inverter control in such a way that the requirement of DC-DC converter is eliminated to harvest the maximum power. The inverter model also maintains near unity power factor regardless of the level of power output and maintains an acceptable level of current harmonics. Finally, the developed model is validated with the output of a commercially used PV module.

[matlab] SINGLE PHASE TRANSFORMER-LESS GRID CONNECTED PV SYSTEM DL : 0: This code presents a single-phase, single-stage current source inverter (CSI) based photovoltaic system (PV) for grid connection. A double-tuned parallel resonant circuit is designed to attenuate the second- and fourth- order harmonics at the inverter dc side. It helps to improve the power quality and system efficiency. A modified carrier based modulation technique for the current source inverter is studied to magnetize the dc-link inductor and to control the switching pattern for the single phase grid-connected CSI. The operation of Single Phase Transformer-less grid connected PV system is verified by the simulation using MATLAB/Simulink software. The results are analyzed and presented.
