Model predictive current control for maximum power point tracking of voltage source inverter based grid connected photovoltaic system

<p>Due to the high demand of grid connected photovoltaic systems, there is a need track maximum power point PV system. As output system dc, should be converter, acting as medium between and dc bus capacitor at all loads. Usually boost converter link duty cycle insulated-gate bipolar transistor in 0 1 for loads during tracking (MPPT). To make stable, balance bus. If voltage constant, will stable. Then transfer just depend on current. For this purpose, active current reference signal generated by setting up across Here generate current, PI controller used taken according peak inverter voltage. The proposed control strategy was evaluated three-phase linked supplied system, which working under varying irradiation conditions.</p>
