Abstract

Due to its inherent intermittency and fluctuation, renewable energy represented by solar energy is not friendly to the power distribution network and connect to the grid. The molten salt solar power tower station equipped with thermal energy storage can effectively compensate for the instability and periodic fluctuation of solar energy, and a reasonable operation control strategy is essential for its peak-regulating operation mode. Based on the law of conservation of energy and conservation of momentum, the dynamic model of a 50 MW solar thermal power system is established. The traditional PID control algorithm is applied to the temperature control of the receiver and the water level control of the power cycle system. Under the disturbance of different environmental factors, including random disturbance of solar direct normal irradiation, step disturbance of molten salt temperature, flow rate, and feedwater temperature disturbance experiments were carried out to obtain the dynamic response curves under different operating conditions. The thermal inertia, tangential thermal stress, and control effect of the receiver are analyzed. The meteorological data on the Spring Equinox is used for the validation of the temperature control of the receiver. The results show that the temperature control strategy of the receiver and the water level of the power cycle system has good robustness. By temperature control, the outlet temperature of molten salt in the receiver can be stabilized at the calibration value in 138 s for a 400 W/m2 DNI fluctuation in 5 s, which reduces the thermal stress caused by large changes in the receiver. By water level control, the evaporator water level can be stabilized at zero water level in 108 s for 5% working load variation, which ensures the safe operation of the steam generation system.
