【 摘 要 】

The objective of this study was to identify ideal sites to locate utility-scale wind and solar farms in Songkhla, a province in southern Thailand. Geographic Information System (GIS) and analytical hierarchy process (AHP) were used to assess various physiographic, environmental and economic siting criteria. The data used in this work were primarily obtained from governmental organizations. Additionally, a Global Horizontal Irradiation (GHI) solar map with a spatial resolution of lkinipixel for the years 2007 - 2015 was obtained from Solargis as well as a 200 m resolution wind resource map of 100 m above ground level obtained from previous research conducted in the study area. The results of the study indicate that Songkhla has potential land areas of up to 66.113 km(2) and 844.93 km(2) available for wind and solar farms respectively, though only areas of 38.749 km(2) and 69.509 km(2) respectively were judged as being highly suitable. Most of these highly suitable areas were located in the Ranot District. The results of this study provide an important starting point for stakeholders interested in investing in renewable energy in Southern Thailand. Knowledge of the suitability of sites will provide a greater level of confidence and therefore likely expedite the renewable energy investment process. (C) 2018 Elsevier Ltd. All rights reserved.
