SIMULATION OF INCREMENTAL CONDUCTANCE MPPT WITH DIRECT CONTROL METHOD USING CUK CONVERTER

PV Module Maximum Power Point Tracker (MPPT) is a p hotovoltaic system that uses the photovoltaic array as a source of electrical power supply. Every photovoltaic (PV) array has an optimum operating point, called the maximum power pwhich varies depending on cell temperature, the insulation level and array voltage. The function of MPPT is needed to operate the PV array at its maximum power point. The design of a Maximum Peak P ower Tracking (MPPT) is proposed utilizing a cuk co nverter topology. Solar panel voltage and current are continuously monitore d by a MPPT, and the duty cycle of the cuk converte r continuously adjusted to extract maximum power. The design consists of a PV array, DC-DC cuk converter and many such algorithms have been proposed. However, one particular algorithm, the Incremental Conductance method, claimed by many in the literatu re to be inferior to others, continues to be by far the most widely used method in commercial PV MPPT’s. The general model was impl emented on Mat lab, and accepts irradiance and temperature as variable para meters and outputs the I-V characteristic and P-V c
