PV Module Monitoring System Based on Low-Cost Solutions: Wireless Raspberry Application and Assessment

摘要: The integration of renewables into power systems has led to multiple studies and analysis in terms grid-power quality, reliability, and/or feasibility. Among different resources be considered as alternative energy systems, wind solar emerge the most mature technologies. With regard photovoltaic (PV) installations, monitoring problems requires detailed analysis, since solar-radiation fluctuations, soiling on panels, or deficiency PV-panel performance can involve unexpected power-output oscillations and, subsequently, undesirable power-generation oscillations. Under this framework, paper describes assesses a wireless low-cost PV-module system based open-source solutions. Our proposal allows us monitor installations at level, giving information regarding PV power-plant performance. proposed is IEC-61724 standard requirements, flexible ad hoc solution with relevant connectivity options. Meteorological electrical data are collected from developed nodes available for subsequent analysis. Detailed solution, well extensive results Spanish plants connected grid, also included paper.
