Abstract

Solutions that increase efficiency in renewable energy are important for environmental sustainability. In this way, dealing with photovoltaic generation a new architecture constituted by power optimizer for photovoltaic systems emerges. Power optimizer is a DC/DC converter, allocated to each one or two photovoltaic modules, that tries to reduce losses in photovoltaic systems, increasing the photovoltaic power generation. Thus, this paper presents the architecture used in a photovoltaic system with power optimizer and a performance simulation for application in a residence and a photovoltaic plant. Thus, it is possible to measure the gain provided by power optimizer in simulated systems. As a result, the application of the photovoltaic system in residence provided better performance than the application in the photovoltaic plant, due to the greater frequency of shading in the photovoltaic modules. Therefore, power optimizer for photovoltaic systems is a solution that can be considered, mainly with the reduction of the cost of power electronics in the future.

光伏系统的模块化结构与功率优化器

提高可再生能源效率的解决方案对环境的可持续性非常重要。这样，处理光伏发电就出现了一种由光伏系统功率优化器构成的新型体系结构。功率优化器是一个DC/DC转换器，分配给每个或两个光伏组件，它试图减少光伏系统的损耗，增加光伏发电量。因此，本文提出了具有功率优化器的光伏系统的结构，并对其在住宅和光伏电站中的应用进行了性能仿真。因此，可以在模拟系统中测量功率优化器提供的增益。因此，由于光伏组件遮阳的频率更高，光伏系统在住宅中的应用比在光伏电站中的应用提供了更好的性能。因此，光伏系统的功率优化器是一个可以考虑的解决方案，主要是未来电力电子成本的降低。
