The ANALYSIS ON MAXIMUM POWER POINT TRACKING ALGORITHM FOR PHOTOVOLTAIC SYSTEMS USING GOLDEN SECTION SEARCH METHOD

Abstract

The photovoltaic (PV) module has been the interface of electrical energy generation from the solar
irradiation. The solar radiation, ambient temperature and solar cell temperature are not constant
throughout the day. So, the maximum power condition varies all the time due to which the efficiency of
PV cell decreases. To increase the efficiency of PV cell maximum power point tracking is used.
Maximum Power Point Tracking (MPPT) is an algorithm that includes charge controller that is used for
extracting maximum power available power from PV module under certain conditions. In addition to the
above conditions, the irradiance on PV module is non-uniform due to shading of trees, clouds etc., called
partial shading. Using conventional MPPT technique such as Perturb and Observe, Incremental
conductance, Hill climbing it is not possible to track maximum power condition in partial shading
condition. The main objective of the present work is to consider MPPT even during partial shading
conditions such that the overall efficiency of the system is improved.
