The characteristics of solar thermal power generation technology and integrated solar combined cycle(ISCC)technology were described.Moreover

the development and operation of current solar hybrid power plant at home and abroad were introduced.ISCC technology provides a feasible solution for comprehensive utilization of clean energy.It can not only make use of renewable energy to generate power

but also overcome the instability of its resources.According to the features of solar energy(only working at daytime)

the ISCC technology can realize auto peak load regulation

making the power generation agree well with load curve that the users require.Currently

the solar energy and gas combined cycle power generation system includes several types

like the tower type

disc type

slot type

Fresnel type and other types.Appropriate form of the ISCC system should be selected according to specific situation of each power plant

to enhance the comprehensive utilization of energy as much as possible.
