ABSTRACT

Optimal control of PV/T module temperature is of great significance for improving PV/T system's photoelectric efficiency and photothermal efficiency. Due to PV/T system's characteristics of large inertia, large delay and complex temperature distribution, in order to stabilize PV/T module temperature at the optimal temperature quickly and accurately, this paper proposes a cascade control strategy based on DMC-PID. Firstly, DMC-PID cascade control is determined as the optimal control strategy of PV/T system according to the characteristics of PV/T module temperature. Secondly, DMC-PID cascade control is studied on PV/T system, including control system design, transfer function acquisition and model establishment, and the results of optimal control are analyzed. Analysis and comparison of simulation results show that DMC-PID has stronger anti-interference and robustness, and has better optimal control effect on PV/T module temperature.
