As shown in fig. 3 and 4, under the condition that the system stores enough heat and the illumination is good, the energy storage power generation system of the present invention can enter a direct work mode. In this case, the circulation of the working medium does not pass through the high-temperature high-pressure water storage and heat storage 7, but directly enters the steam turbine 3 to do work after the heat absorber 2 absorbs enough heat.
The specific circulation mode is as follows: the low-temperature water in the low-temperature water storage 5 is delivered to the heat absorber 2-1.

As shown in fig. 7 and 8, in the case of insufficient solar light at night, rainy day, etc., the energy storage and power generation system of the present invention can enter the energy release working mode, and the high temperature medium stored in the high temperature and high pressure water storage and heat storage 7 before drives the generator 6 to work through the steam turbine 3. The specific cycle pattern in this case is: when the valve 26 is opened, the high-temperature water stored in the high-temperature high-pressure water storage and heat storage device 7 enters the steam turbine 3 from the upper part of the high-temperature high-pressure water storage and heat storage device 7 through the balance steam storage tank 40 in the form of steam, and the steam is generated to drive the generator 6 to work.
