Description: To keep overall output power per
unit cost low, the grid-connected converters should be
able to extract the maximum available power from the
PV arrays. Since the PV array characteristic is highly
nonlinear, maximum power point tracking (MPPT) of
the PV arrays becomes rather challenging.

Description: Single-stage grid-connected photovoltaic (PV) systems
have advantages such as simple topology, high efficiency, etc.
However, since all the control objectives such as the maximum
power point tracking (MPPT), synchronizationwith the utility voltage,
and harmonics reduction for output current need to be considered
simultaneously, the complexity of the control scheme is much
increased

Description: 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.
Firstly, the paper introduces the grid-connected PV system research background and significance, the current situation at home and abroad, key issues of grid-connected PVsystem, it also analyzes the electrical characteristics and equivalent model of PV cell, it also analyses the hot spot effect and the difference performance of PV cell in partial shading then, the paper introduces the principle of the conventional maximum power point tracking methods, its advantages and disadvantages, applicable occasions and problems

Description: 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.

Description: Two demos illustrate use of SimPowerSystems for modeling a PV array connected to a utility grid.
PVarray_Grid_IncCondReg_det.mdl is a detailed model of a 100-kW array connected to a 25-kV grid via a DC-DC boost converter and a three-phase three-level Voltage Source Converter (VSC). Maximum Power Point Tracking (MPPT) is implemented in the boost converter by means of a Simulink model using the “Incremental Conductance + Integral Regulator” technique.
PVarray_Grid_PandO_avg.mdl is an average model of a 200-kW array connected to a 25-kV grid via two DC-DC boost converters and a single three-phase VSC. The MPPT controller based on the “Perturb and Observe” technique is implemented by means of a MATLAB Function block that generates embeddable C code.

Description: The only emissions associated with PV power generation are those the production
of its components. After their installation they generate electricity the solar
irradiation without emitting greenhouse gases. In their lifetime, which is around 25
years, PV panels produce more energy than that for their manufacturing [2]. Also they
can be installed in places with no other use, such as roofs and deserts, or they can
produce electricity for remote locations, where there is no electricity network. The latter
type of installations is known as off-grid facilities and sometimes they are the most
economical alternative to provide electricity in isolated areas.-The only emissions associated with PV power generation are those the production
