“…Hasta el momento, los proyectos desarrollados consideran diferentes unidades de análisis que pueden variar desde la escala regional y nacional (Izquierdo et al, 2008) a los núcleos urbanos y barrios (Jo et al, 2011). La estimación del potencial fotovoltaico está ampliamente relacionada con la morfología y configuración del entorno urbano (Byrne et al, 2014). La cartografía digital y los servicios catastrales son fuente de datos habituales para establecer la distribución de los edificios (Hofierka y Kaňuk, 2009;Mainzer et al, 2014), que con el complemento de las imágenes aéreas, facilitan la identificación de las diferentes tipologías de los tejados (Bergamasco y Asinari, 2011).…”

RESUMENEste trabajo describe un modelo geográfico que evalúa la posibilidad de generar energía eléctrica en entornos urbanos, delimitando aquellas zonas de los tejados adecuadas para la instalación de sistemas fotovoltaicos. El estudio, realizado para el municipio de Miraflores de la Sierra (Madrid), se ha desarrollado basándose en un modelo urbano tridimensional generado con una nube de puntos LIDAR que aporta una adecuada descripción del entorno urbano. El modelo no sólo realiza cálculos globales para una zona, sino que también proporciona, como resultado final, datos del potencial fotovoltaico de los edificios, por lo que ha sido necesario incluir en el modelo, herramientas desarrolladas en el lenguaje de programación Python. También, utilizando la enorme versatilidad de los Sistemas de Información Geográfica e internet, se ha implementado un visor geográfico que permite la consulta, de forma abierta, de los principales resultados obtenidos.Palabras clave: LIDAR, SIG, radiación solar, energía solar, generación distribuida, autoconsumo fotovoltaico.

“…In addition, cities account for around 70% of man-made CO 2 emissions, hence representing a major contributor to climate change [2,3]. As a result, many cities around the world-including those in fast-growing developing countries where urban growth will be the largest-have in many cases set up urban plans to: (a) accommodate rapidly increasing population; (b) reduce energy consumption; and (c) develop policies to mitigate adverse impact of a changing climate [4][5][6].…”

Abstract:Reliance on fossil fuel-driven energy supply is a major contributor to global emissions. In order to stay within the Paris Agreement's temperature rise limits, current and growing energy consumption will need to be significantly underpinned by deployment of low/non-carbon power generation. This work promotes power generation at the megawatt scale from solar photovoltaics (PV) systems deployed in untapped car parking areas, which are estimated to represent up to~6.6% of the urban footprint within cities. The methodology developed is globally applicable to support PV development, including site selection and PV array configuration. It is underpinned by a case study in a university campus, which has a similar footprint as assigned in cities for vehicle parking. The methodology demonstrates that less than 1% of the available parking spaces are affected by shadows from surrounding buildings or vegetation. The work shows that by utilising such parking areas within the selected campus a PV installation with a capacity of~36.4 MWp, which can generatẽ 66.2 GWh of electricity annually, would be feasible. Financial analysis based on multiple scenarios indicates that a 50% return on investment is achievable over 25 years at an export tariff of USD ¢4.5/kWh, which is commensurate with the latest granted bids for a similar export tariff.

“…The first is related to how solar potential in urban areas can be evaluated in order to be efficiently capitalized on by the installation of photovoltaic system in building [12]. The second is what kind of delimitation criteria can be considered to identify urban cells as independent systems in which the energy balance results from the differential between the solar energy supply and the building's energy consumption [13].…”

Abstract:Recent growth in the use of photovoltaic technology and a rapid reduction in its cost confirms the potential of solar power on a large scale. In this context, planning for the deployment of smart grids is among the most important challenges to support the increased penetration of solar energy in urban areas and to ensure the resilience of the electricity system. As part this effort, the present paper describes a cellular approach to a Net-Zero energy concept, based on the balance between the potential solar energy supply and the existing consumption patterns at the urban unit scale. To do that, the Geographical Urban Units Delimitation model (GUUD) has been developed and tested on a case study. By applying the GUUD model, which combines Geographic Information Systems (GIS), parametric modelling, and solar dynamic analysis, the whole area of the city was divided into urban cells, categorized as solar producers and energy consumers. The discussion around three theoretical scenarios permits us to explore how smart grids can be approached and promoted from an urban planning perspective. The paper provides insights into how urban planning can be a driver to optimize and manage energy balance across the city if the deployment of smart grids is correctly integrated in its operative process.
