Abstract

This study aims to present the results of applying a computational tool developed to perform a technical-economic feasibility analysis of a large-scale Linear Fresnel Reflector (LFR) solar power plant. The viability analysis indicators were obtained considering that the electricity produced trades at the Regulated Contracting Environment of the Brazilian Electricity Market. The parametric structural optimization method is used to optimize the technical parameters of the plant. A case study was conducted to analyze the viability of Implementing a 100 MW LFR power plant in the five regions of Brazil. The results indicated that Northeastern is the best region to install this power plant. However, the project is not viable in all cities analyzed. A sensitivity analysis (SA) of some strategically selected variables was conducted to evaluate its impacts on the project's net present value of an optimized LFR plant located in the city with the best technical performance. Finally, an optimistic scenario was evaluated considering the net present value's response to the parameters investigated in the SA. For this scenario, the results indicated the project's economic viability.

线性菲涅耳反射器技术在巴西:技术经济评价

本研究旨在展示应用计算工具对大型线性菲涅耳反射器(LFR)太阳能发电厂进行技术经济可行性分析的结果。考虑到生产的电力在巴西电力市场受监管的承包环境下进行交易，得出可行性分析指标。采用参数结构优化方法对装置的技术参数进行优化。进行了一个案例研究，以分析在巴西五个地区实施100兆瓦低堆电厂的可行性。结果表明，东北地区是该电站的最佳选址地区。然而，该项目并非在所有被分析的城市都可行。对战略选择的一些变量进行敏感性分析(SA)，以评估其对位于技术性能最佳的城市的优化LFR工厂的项目净现值的影响。最后，考虑到净现值对SA中所调查参数的响应，评估了一个乐观的情景。在这种情况下，结果表明了项目的经济可行性。
