A New Maximum Power Point Tracking Algorithm for the Photovoltaic Power System

The use of maximum power point tracking (MPPT) techniques is widely discussed and employed for photovoltaic array in micro-grid systems to optimize the PV output power transferred to the load. There are various types of converter models are employed as MPPT circuits such as buck, boost or buck-boost converters. The MPPT circuit is becoming an intermediate component between the load and the PV panel. In this paper, the MPPT boost converter is selected and a new control algorithm for the MPPT controller, namely new hill climbing method, is introduced. This method is also compared with an existing popular MPPT algorithm (P&O) to confirm its superior performance by using the MATLAB simulation.
