The maximum power point tracking for stand-alone photovoltaic system using current based approach

This paper presents the maximum power point tracking for stand-alone photovoltaic system using current based technique. This method mitigates the disadvantage of conventional perturb and observe (P&O) technique in term of both transient and steady-state responses. The simulation results show that the proposed current based MPPT technique can provide the maximum power point value closed to the corresponding maximum power of photovoltaic for each irradiance. Both transient and steady state responses are better than those of conventional P&O technique.
