Abstract Increasing the exploitation of renewable energy sources (RES) is a key element for reducing the detrimental consequences of greenhouse-gases emissions and for satisfying the growing demand for energy. Solar power plays a central role having the potential to completely satisfy the world energetic needs. Locating optimal sites for installing solar plants is therefore an important task deeply affecting the long term profitability of such plants. The present paper proposes a filtering method to select a subset of efficient locations in order to reduce the dimensionality of the original problem when a large territory is screened for locating optimal sites for large-scale solar plants. It is based on the idea of preference relations and Pareto dominance and, avoiding to operate an inter-comparison of different locations’ attributes, it can be considered assumptions-free. Moreover, the paper applies such filtering method, together with an analysis of economic viability, to Italy, a country with relatively high potentials in terms of solar energy that currently lacks an optimal site selection analysis. Once applied, the filter reduces the original set of feasible locations by more than 99%. The resulting Pareto efficient locations, evaluated through five selected criteria, are concentrated in the southern part of Italy and, particularly, in the islands of Sicily and Sardinia, where also the economic viable locations are mostly found.

一种应用于意大利的大型太阳能电站选址的第一阶段筛选方法

摘要 增加可再生能源 (RES) 的开发是减少温室气体排放的不利后果和满足不断增长的能源需求的关键因素。太阳能发挥着核心作用,具有完全满足世界能源需求的潜力。因此,找到安装太阳能发电厂的最佳地点是一项重要的任务,对此类发电厂的长期盈利能力有着深远的影响。本文提出了一种筛选方法来选择有效位置的子集,以便在筛选大面积区域以定位大型太阳能发电厂的最佳位置时降低原始问题的维数。它基于偏好关系和帕累托优势的思想,避免对不同位置的属性进行相互比较,它可以被认为是无假设的。此外,本文将这种过滤方法与经济可行性分析一起应用于意大利,一个太阳能潜力相对较高的国家,目前缺乏最佳选址分析。一旦应用,过滤器将原始可行位置集减少 99% 以上。由此产生的帕累托有效地点,通过五个选定的标准进行评估,集中在意大利南部,特别是西西里岛和撒丁岛,那里也大多是经济可行的地点。一个在太阳能方面具有相对较高潜力的国家,目前缺乏最佳选址分析。一旦应用,过滤器将原始可行位置集减少 99% 以上。由此产生的帕累托有效地点,通过五个选定的标准进行评估,集中在意大利南部,特别是西西里岛和撒丁岛,那里也大多是经济可行的地点。一个在太阳能方面具有相对较高潜力的国家,目前缺乏最佳选址分析。一旦应用,过滤器将原始可行位置集减少 99% 以上。由此产生的帕累托有效地点,通过五个选定的标准进行评估,集中在意大利南部,特别是西西里岛和撒丁岛,那里也大多是经济可行的地点。
