On the basis of thermal energy storage technology and dual-generator co-generation ideas

a novel solar tower thermal power co-generation system was proposed.The system applies two thermal energy storages and two turbines.In this system

the high temperature gas turbine is combined with the high temperature thermal storage

and the steam turbine is combined with the medium temperature thermal storage.The two turbines not only can work together

but also can run separately for a short time.The estimation results show that

peak efficiency of the tower solar thermal power system is up to 20.5%

and the annual average power generation efficiency is 13.37%.This system can take full use of solar heat

enhance power generation efficiency

and reuse the waste heat.
