A Novel Multi Input DC-DC Converter for Integrated Wind, PV Renewable Energy Generated System

––The objective of this paper is to propose anovel multi-input power converter for the gridconnected hybrid renewable energy system in order to simplify the power system and reduce the cost. The proposed multiinput power converter consists of a Cuk fused multi-input dc–dc converter and a fullbridge dc– ac inverter. The incremental conductance method is mainly used to accomplish the maximum power point tracking (MPPT) algorithm for input sources. The operational principle of the proposed multi-input power converter is explained. A multi-input power converter (MIPC) which operates in four modes: first an operation type wherein power is delivered to dc Bus from hybrid renewable energy sources; second a single type wherein only one renewable energy source supplies power to the dc Bus; third an inverter typewherein power is delivered to dc Bus from ac grid viainverter module, and forth a battery type whereinpower is delivered to dc Bus from batteries withoutrenewable energy source. The integration of the dc Busand a hybrid renewable power supply system isimplemented and simulated usingMATLAB/SIMULINK. A hybrid renewable powerenergy which integrates the solar energy, wind-power.
