Energy Prediction in Urban Photovoltaic Systems

Este artículo propone un nuevo método para estimar la potencia y energía producida por sistemas fotovoltaicos urbanos, los cuales son comúnmente cubiertos por sombras que afectan su desempeño. La solución se basa en un algoritmo para procesar, rápidamente, un modelo preciso que considera el efecto de las sombras. Esta solución provee un mejor desempeño en comparación con aproximaciones clásicas, ya que reduce significativamente el tiempo de cálculo sin introducir errores sensibles, permitiendo la simulación de largos periodos de operación, e.g. meses y años. Por lo tanto, esta solución es apropiada para realizar estimaciones de energía orientadas a análisis económicos, e.g. cálculo del tiempo de retorno de la inversión, así como para soportar el diseño de instalaciones fotovoltaicas, permitiendo el cálculo preciso del número de módulos requeridos para suplir el perfil de carga.This paper proposes a new method to accurately estimate the power and energy production in urban photovoltaic (PV) systems, which are commonly covered by shades affecting its performance. The solution is based on an efficient algorithm designed to compute, in short time, an accurate model accounting for the shades impact. In such a way, the proposed approach improves classical solutions by significantly reducing the processing time to simulate long periods, e.g. months and years, but without introducing sensible errors. Therefore, this approach is suitable to estimate the production of PV systems for economical analyses such as the return-of-invested time calculation, but also to accurately design PV installations by selecting the right number of photovoltaic modules to supply the required load power.  

Smart Technologies. SmartTech-IC 2021: Proceedings of the Second International Conference on Smart Technologies, Systems and Applications

This book contains a group of selected papers, which were presented at the Second International Conference on Smart Technologies, Systems and Applications (SmartTech-IC 2021) held on December 1-3, 2021 in Quito, Ecuador. The SmartTech-IC conference aims to attract researchers, scientists and technologists from some of the top companies, universities, research groups, and government agencies from Latin America and around of the world to communicate their research results, inventions and innovative applications in the area of smart science and the most recent smart technological trends. The second edition of SmartTech-IC conference was organized by the Universidad Politécnica Salesiana (Campus Giron), a private institution of higher education with social purposes, nonprofit and co-financed from the Ecuadorian State. The SmartTech-IC conference has been conceived as an academic platform to promote the creation of technical and scientific collaboration networks. The goal of the conference was addressed some relevant topics related to smart technologies, smart systems, smart trends and applications in different domains in the field of computer science and information systems that represent innovation in current society
