Description: The PV array has been simulated at one year period and other code sources are
been discussed. In order to extract the voltage deviation from the array, we intent to
apply the formula of the MPP to these codes. Our approach, considering the hole
system, has not been totally implemented in Simulink. The grid utility and the control

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: 光伏电池阵列输出功率受光照强度和温度变化的影响，因此最大功率点跟踪（MPPT）技术广泛应用于光伏系统中。在所有最大功率点(MPP)控制策略中，扰动观察（P&O）MPPT算法因易实现被广泛应用，然而它的缺点是在稳定工作状态下工作点通过MPP 时会导致能量振荡损耗，并且在光照强度或温度发生突变时表现较差的动态响应。在本文中，提出一种改进型变步长扰动观察MPPT 算法，此方法依据工作点动态调整步长变化，与传统固定步长方法比较，本文提出的方法能有效地提高MPPT 速度和转换效率，通过仿真和实验结果分析，验证了此改进算法的可行性。-PV array output power by the light intensity and temperature changes, the maximum power point tracking (MPPT) technology is widely used in photovoltaic systems. In all the maximum power point (MPP) control strategy, the disturbances observed (P & O) MPPT algorithm due to easy implementation is widely used, but its drawback is that the steady-state operating point by MPP will lead to energy oscillations loss, and in the light intensity or temperature when the poor performance of a mutation in the dynamic response. In this paper, propose a modified variable step disturbance observed MPPT algorithm, this method dynamically adjusted according to operating point step change, with the more traditional fixed-step method, the proposed method can effectively improve the MPPT speed and efficiency, The simulation and experimental results verify the feasibility of this improved algorithm.

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.
