Enhancement of photovoltaic inverters efficiency using an advanced MPPT technique in variable weather conditions

太阳能系统是解决气候变化和长期能源安全问题的有前途的解决方案，** 特别是在天气条件多变的地区。当光伏阵列的各个模块接收不等量的太阳辐照度时，光伏（PV）能量 ** 系统的性能可能受到挑战。这样的条件导致不确定的多个局部最大功率点（MPP）的电气特性。这仍然是一个挑战，全球优化，以确保光伏系统运行在其全球 **MPP，而不是在本地的。因此，需要进行研究，以减少光伏系统在 ** 非均匀辐照模式下的能量损失。Solantro Semiconductor Corp.是开发用于分布式和可扩展可再生能源系统的模块集成 ** 电子产品的芯片组和参考设计的领导者。为了提高光伏逆变器 ** 的性能，Solantro需要将先进的控制器纳入其DC-DC功率优化器，以在全局MPP下运行 **。这项大学与工业界合作的提案旨在开发一种先进的最大 ** 功率点跟踪（MPPT）技术，以找到提高光伏逆变器效率的全球MPP。** 预期结果有可能改进基于 ** 新型实时MPPT控制器的先进光伏逆变器的设计和制造。该平台的目标是非常具有成本效益，高度可靠，并易于 ** 适应各种光伏逆变器。

Solar systems are promising solutions for addressing climate change and long-term energy security issues,**especially in areas experiencing variable weather conditions. The performance of photovoltaic (PV) energy**systems can be challenged when individual modules of a PV array receive unequal amounts of solar irradiance.**Such conditions lead to uncertain multiple local maximum power points (MPPs) on their electrical**characteristics. It remains a challenge of global optimization to ensure that PV systems operate at their global**MPP rather than at local ones. Therefore, research is needed to reduce energy losses of PV systems under**non-uniform irradiation patterns.**Solantro Semiconductor Corp. is a leader in developing chipsets and reference designs for module-integrated**electronics used in distributed and scalable renewable power systems. In order to increase the PV inverter**performance, Solantro needs to incorporate an advanced controller into its DC-DC power optimizers to operate**at the global MPP. This collaborative university-industry proposal aims to develop an advanced Maximum**Power Point tracking (MPPT) technique to find the global MPP that will increase PV inverters efficiency. The**expected results have the potential to improve the design and manufacturing of advanced PV inverters based on**a new real-time MPPT controller. The platform is targeted to be very cost-effective, highly reliable and readily**adaptable to a variety of PV inverters.
