论文摘要
通过增加能源需求，使用光伏系统逐渐扩展。这种能量的丰富性和可用性已转向可再生能源的最重要来源之一。不幸的是，光伏系统有两个大问题：首先，这些系统的能量转换效率非常低（在某些情况下为12％至42％的ACT）。其次，太阳能电池产生的功率取决于非线性条件，例如太阳辐射，温度和电荷特征。据此，接收到的光伏电池的最大功率取决于不同的非线性变量，必须连续追踪，因为电池的最大接收功率（通过控制器）。在这项研究中，通过使用最大功率点跟踪（MPPT）以包含连接到网格的两种不同模式使用最大功率点跟踪（MPPT）研究了光伏系统的提高效率，并通过MATLAB软件模拟与网格断开连接。获得的结果表明，该提出的技术能够改善光伏电池的电流，电压和功率输出。
Using Photovoltaic systems is gradually expanded by increasing energy demand. Abundance and availability of this energy, has turned to one of the most important sources of renewable energy. Unfortunately, photovoltaic systems have two big problems: first, those have very low energy conversion efficiency (in act between 12 and 42 percent under certain circumstances). Second, the power produced by the solar cell depends on nonlinear conditions such as solar radiation, temperature and charge feature. According to this, received power maximum of photovoltaic cells depends on different non-linear variables, it is necessary to be continuously traced, as maximum received power of the cell (by controller). In this research, the increasing efficiency of photovoltaic systems has been investigated by using Maximum Power Point Tracking (MPPT) in two different modes contained connected to the Grid and disconnected from the grid with simulation by MATLAB software. The obtained results showed that the proposed technique is able to improve the current, voltage and power output of photovoltaic cells.
