Description
Summary:Solar energy has become one of the magnificent renewable energy sources of electrical energy since it remarkably preserves the environment through its renewing capability and delivers better performance with low cost. To link the solar PV to the utility grid, a PV connected grid system with switched boost landsman converter is proposed through the ANFIS based MPPT technique. As the output voltage of PV system is not efficient, it is fed to a switched boost landsman converter, which offers improved voltage gain with minimized switching losses. Along with the solar PV, a battery system uses a bidirectional Buck-Boost battery converter to balance the power run in the proposed model. The proposed converter is controlled by using the ANFIS based MPPT technique to track maximum power from the PV system, through which the DC-link voltage is maintained as constant. The output of converter is fed to the grid through a three phase VSI, which converts the DC voltage into AC voltage. The LC filter is employed to improve the output of the VSI. With the aid of DQ theory, the switching pulses of three phase VSI are generated by comparing the reference signal with the carrier signal, through which the VSI is controlled. Thus the grid synchronization is achieved with the THD of 1.02% . This proposed strategies are implemented in MATLAB and the results were attained.
