摘要

本文的目的是评估将带电加热器的电-热系统集成到熔盐太阳能塔以增加热能储存系统的充电并扩大CSP电厂的容量时的趋势。为此，考虑了几种经济技术边界条件，进行了技术经济分析。结果表明，过剩电力的可用性及其成本有显著影响。根据系统布局和用电成本的不同，此类电厂的整体LCOE最多可降低25%。因此，这种电转热系统可以为太阳能热电厂提供经济和战略效益。

Power-to-heat in CSP systems for capacity expansion

The objective of this paper is the evaluation of trends when a power-to-heat system with electrical heaters is integrated to a molten salt solar tower to additionally charge the thermal energy storage system and to expand the capacity of the CSP plant. Therefore a techno-economic analysis was carried out considering several economical and technical boundary conditions. The results show a significant impact on the availability of excess electricity and its cost. Depending on system layout and the cost of the used electricity the overall LCOE of such plants can be reduced by up to 25%. Therefore such power-to-heat systems can offer an economic and strategic benefit to solar thermal power plants.
