Maximum Power Point Tracking Based on Sliding Mode Control

Abstract EN

Solar panels, which have become a good choice, are used to generate and supply electricity in commercial and residential applications.

This generated power starts with the solar cells, which have a complex relationship between solar irradiation, temperature, and output power.

For this reason a tracking of the maximum power point is required.

Traditionally, this has been made by considering just current and voltage conditions at the photovoltaic panel; however, temperature also influences the process.

In this paper the voltage, current, and temperature in the PV system are considered to be a part of a sliding surface for the proposed maximum power point tracking; this means a sliding mode controller is applied.

Obtained results gave a good dynamic response, as a difference from traditional schemes, which are only based on computational algorithms.

A traditional algorithm based on MPPT was added in order to assure a low steady state error.
