A new controlling method for maximum power point tracking in photovoltaic systems by using model predictive control (MPC)

High cost of photovoltaic systems necessitate to get them in high efficiency utilization systems. Among existing methods for maximum power point tracking (MPPT), Incremental conductance method by having a relatively high speed and accuracy is unable to make a good compromise between radiation and ambient temperature. In this paper in addition to improving the Incremental conductance method, a new and robust method based on model predictive control (MPC) is presented to trace and extract the current, corresponding to the maximum power point. This method is real-time method so the results of simulation confirm the speed and accuracy of this method.
