A Review of Maximum Power Point Tracker in Photovoltaic Systems

Abstract

Fossil fuels used for electric power generation has created several problems on the environment including global warming and greenhouse effect. This has led to an era in which the increasing demand of power has to be met by Grid connected system that are based on renewable on sources such as wind, solar and hydro power that are renewable in nature. Generating electrical power from solar energy is very popular. The generation of electricity from photovoltaic (PV) arrays has been increasingly considered as a prominent alternative to fossil fuels. However, the conversion efficiency is typically low and the initial cost is still appreciable. A required feature of a PV system is the ability to track the maximum power point (MPP) of the PV array. Besides, MPP tracking (MPPT) is desirable in both grid-connected and stand-alone photovoltaic systems. There are many studies aiming at increasing the efficiency and designing simpler systems. Electrical power generated by PV cells depends on solar irradiances, ambient temperatures and electrical loads. To transfer maximum available power from PV cells to the grid, Maximum Power Point Tracker (MPPT) algorithms have been developed and implemented to make it better. In this Article, we studied the existing literature on Maximum Power Point Tracker in PV System.
