ABSTRACT

The present paper proposes a spatial model for the purpose of helping Decision Makers (DM) to select a location for Solar Power Plants (SPPs) in the Misrata District, Western Libya. In this regard, the use of the Geographic Information System (GIS), SWARA (Step-wise Weight Assessment Ratio Analysis), and DEMATEL (Decision-Making Trial and Evaluation Laboratory) multi-criteria methods is suggested. The goal of this paper is to develop a new multi-criteria spatial model to identify the best locations for Solar Power Plants (SPP). Such model considers six constraints and eight assessment criteria that are gathered into financial, social, and specialized measures. The hybrid SWARA-DEMATEL (SWA’TEL) model is utilized to assess the weight coefficients of the suggested criteria. The final suitability map is presented utilizing raster cells (alternatives) that are given values ranging from 1 (the least suitable) to 5 (the most appropriate). As the outcomes indicate, an area of 1 667 km² in Misrata is entirely fit for the SPPs establishment. A sensitivity analysis performed by changing the criteria weights shows that the model is useful in selecting appropriate locations for developing SPPs projects. The model could also be used effectively to help locate appropriate sites for solar farms being installed in other areas with similar geographical conditions.

摘要

本文提出了一种空间模型，旨在帮助决策者（DM）选择位于利比亚西部米苏拉塔地区的太阳能发电厂（SPP）的位置。在这方面，建议使用地理信息系统（GIS），SWARA（逐步权重评估比率分析）和DEMATEL（决策试验和评估实验室）多准则方法。本文的目的是开发一种新的多准则空间模型，以识别太阳能发电厂（SPP）的最佳位置。这种模型考虑了六个约束条件和八个评估标准，这些条件被收集到财务，社会和专业措施中。混合SWARA-DEMATEL（SWA'TEL）模型用于评估建议标准的权重系数。最终的适用性图是利用栅格像元（替代像）给出的，这些栅格像元的值范围为1（最不适合）到5（最不适合）。结果表明，面积为1667公里Misrata中的²完全适合SPP的建立。通过更改标准权重进行的敏感性分析表明，该模型可用于选择适当的位置以开发SPP项目。该模型还可以有效地用于帮助找到在地理条件相似的其他地区安装太阳能电站的合适地点。
