Modelling and Simulation of Hybrid Control Systems in Solar Cell-Battery-Super Capacitor

Abstract

Solar cell technology is very suitable to be applied to the power generation system. The dynamics of the slow solar cells must be compensated through hybridization with batteries and / or super capacitors by a DCDC Converter. Solar cells are also very appropriate to be integrated on renewable energy schemes (Renewable Energy), such as wind turbines, fuel cells and so forth. This study will be designed on the feedback control method of hybrid solar cells, batteries and super capacitors in which the use of such methods is to regulate the output voltage in accordance with the desired bus at 12 volts by using three sources mentioned above, each of which possessed different physical dynamics. The design of hybrid control includes hybrid systems modelling and design of state feedback control. The results of the control design are tested through simulation and implemented in the real system. The simulation results show that the hybrid control design goes well which produces a voltage output according to the desired bus of 12 Volts which overshoot the closed loop system by 0.6% compared with the closed loop system by 1.0%.
