Institute of Engineering Thermophysics, Chinese Academy of Sciences, Haidian District, Beijing 100080, China) ABSTRACT: Based on the actual condition to develop solar 一个方面必须加速可再生能源的开发和利用。太阳 energy in China and method of synthetic cascade utilization of 能以其分布广泛，储量丰富受到了广泛关注。大力 energy, a novel solar tower power system was proposed. The 开发利用太阳能，将会改变我国能源短缺和不合理 two-stage thermal storage technology was adopted by this new 的能源结构，使能源供应多样化，同时可以解决环 system. Solar energy was stored respectively according to its 境污染问题。因此，研究开拓太阳能热力发电系统 different energy level. Its operation mode was switched neatly. 成为当今能源动力领域研究的热点与前沿课题[1-4] 。 The simulation indicates that the solar thermal power peak efficiency of 1 MW power output was 10.6%, and the annual 随着太阳能热发电技术和经济指标的进步，以 mean efficiency was 5.1%. The result shows that the key point 及全球化石燃料的逐渐枯竭和对减排 CO2 的要求， to improve system performance is mainly due to choose
