A maximum power point tracking method for PV system with improved gravitational search algorithm

Photovoltaic (PV) system has gradually become research focus in the field of renewable energy power generation, and the output efficiency of PV system is the major concern of researchers. There are obvious non-linear characteristics in the output of PV system, and it will be greatly affected by external environment. For achieving the maximum output power, PV system must operate under the guidance of maximum power point tracking (MPPT) methods...
