Description
Summary:Nowadays, the development of the photovoltaic (PV) technology is consolidated as a source of renewable energy. The research in the topic of maximum improvement on the energy efficiency of the PV plants is today a major challenge. The main requirement for this purpose is to know in real-time the working point of each of the PV modules that integrate the PV field and improve their performance. For this purpose, a Power Line Communications (PLC) based Smart Monitoring and Communications Module, which is able to monitor at PV level their operating parameters, has been developed at the University of Málaga. This device can check if any of the panels is suffering any type of overriding performance, due to a malfunction or partial shadowing of its surface. In this paper, the data acquisition system is described and subsequently the solution of the most energy-efficient path was arised from information acquired in real-time. Through graph theory and Minkoski’s paths have been possible to deduce the recursive programming algorithm that generate a dynamic reconfiguration to solve this problem.
