Then, PV systems are not only power generation systems but also active systems to optimize the grid performance. In general, control structures are hybrid systems that combine linear and non-linear techniques; as well as classical techniques, advanced control and artificial intelligence methods.
This Review discusses some of the recent developments in the design and implementation of such photonic elements in thin-film photovoltaic cells. Photovoltaic (PV) devices can effectively convert sunlight into clean electrical power and could provide a virtually unlimited amount of energy to our world.
The most popular are flying capacitor, neutral-point-clamped inverters, T-type structures, cascaded H-bridge, and Packed U-Cell converter . In PV systems controller design, there are two fundamental features to consider, category and architecture. The possible categories in PV systems are islanded and Grid-connected systems.
The latest top-notch devices still exhibit relatively poor light utilization compared to silicon solar cells. Thus, light management strategies have potential to achieve further improvement towards the theoretical limit.
