Abstract: Integrated solar combined cycle(ISCC)power generation system can effectively utilize the solar power by improving the photoelectric conversion efficiency and reducing fuel consumption of original gas-steam combined cycle system,which has attracted more attentions in recent years.The development of four typical ISCC system integration modes were studied and summarized ,and their economic performances and performance evaluation indicators were explored. According to the intermittent of solar power and the peak-shaving characteristic of China's power generation systems,the features of off-design working conditions of the integrated system were analyzed and verified systematically by domestic and foreign engineering demonstration projects. The research achievements will provide guidance for the design and operation optimization of ISCC systems.
