APPLICATION OF A GEOGRAPHICAL INFORMATION SYSTEM TO THE FEASIBILITY ANALYSIS OF PVELECTRICITY SUPPLY IN RURAL ENVIRONMENTS

摘要

The Geographical Information Systems (GIS) are a wide spread and very valuable tool able to manageand analyse spatial multivariate and interdisciplinary data sources. Their application to the feasibility assessment for the implementation of renewable energy sources is still recent but they have been proven as very adequate decision support elements according to the characteristic dependencies involved in this kind of studies, including site extrinsic (climate, solar and wind resources,…) and intrinsic (electrical feeding patterns, topography, grid proximity,…) variables. This work presents an example of the use of ArcView? GIS software in the estimation of feasibility criteria for the adoption of solar photovoltaic electricity supply systems in a rural area located South Eastern Spain takinginto account the eventual agronomic and/or dwelling land use and its corresponding energy demand. In this analysis,a set of data sources have been integrated ranging from remote sensed solar radiation to digital elevation models to evaluate correction factors for grid connection costs, apart of crops placement and water demands. The obtainedgraphical output allows to users and systems installers for an immediate functional and economical estimation ofeventual projects related to rural development of the studied zone.
