本文介绍了一个中型到大型（290-500兆瓦接收器热发电）中央接收站考虑到目前的市场趋势的参数分析。分析分为4个步骤：·规模和位置分析：对于一个中型到大型的中央接收器发电厂，已经分析了三个涡轮机功率和三个不同的位置，这些位置涉及到发电塔发电厂的开发，以评估对太阳能场和接收器子系统的设计特性以及平准化电力成本的影响。·技术分析：由于目前运行的商业塔式发电厂主要使用蒸汽和熔融硝酸盐，本分析比较了两种主要技术，在类似的设计条件下，在没有热能储存的情况下评估两者。·存储分析：热能存储增加了两种技术（蒸汽和熔融硝酸盐）的发电价值和工厂容量系数。因此，分析为每个优化的太阳能场和接收器热功率显示了涡轮机功率和热能存储的最佳组合，可最大限度地降低两种技术的均衡电力成本。·组件成本分析：市场趋势集中在通过扩大工厂规模和提高规模经济来降低特定成本。因此，根据太阳能行业广泛接受的基准成本参数，对电力成本的主要组成部分的具体成本进行了分析，以引导研究和开发工作的方向。
This paper presents a parametric analysis for a medium to large size (290–500 MWthreceiver thermal power) central receiver plant considering the present market trends. The analysis is divided in 4 steps:•Size and location analysis:for a medium to large size central receiver power plant, three turbine power and three different locations that are involved in the development of power tower plants, have been analyzed to assess the impact over the design characteristics of the solar field and receiver sub-systems and over the levelized electricity cost.•Technology analysis:as commercial power tower plants in operation today are mainly using steam and molten nitrate salts, the present analysis compares the two main technologies, without thermal energy storage to evaluate both under similar design conditions.•Storage analysis:thermal energy storage increases the value of electricity produced and the plant capacity factor for both technologies (steam and molten nitrate salts). For this reason, the analysis shows for each optimized solar field and receiver thermal power, the optimum combination of turbine power and thermal energy storage that minimizes the levelized electricity cost, for both technologies.•Component’s cost analysis:market trends are focused on the specific cost reduction by means of larger plant size and through an improved economy of scale. As a result, and based on baseline cost parameters widely accepted in solar industry, an analysis over the specific costs of major components on the electricity cost has been carried out, to lead where the research and development efforts should be made.
