| Abstract |
In this paper, application and comparative analysis of anti-windup method for improving the response of voltage control of MPPT method in photovoltaic generation system is proposed. In the case of MPPT, PI control can be mainly used to control a target voltage from a reference voltage that continuously changes according to changes in the surrounding environment for optimal control of PV power production. However, its PI controller has accumulated saturation of errors in the process of integrating the errors, so it is necessary to consider the integrator windup. This problem could affect the power production efficiency when performing MPPT control, so this paper sought to verify its effect by applying the follow-up anti-windup technique to MPPT control to improve the integral windup phenomenon. It could be confirmed from the results of the presented simulation that the application of the proposed algorithm mixed is more effective to improve the control performance of the photovoltaic system. |
