Photovoltaic Array Reconfiguration Strategy for Maximization of Energy Production

الملخص EN

This paper presents a dynamic reconfiguration method for electrical connections in a Series-Parallel connected photovoltaic array under partial shading conditions.

It is desirable to extract the maximum energy from the array, but it does not occur in situations where the modules have different points of operation caused by shading.

The proposed method is then characterized by the maintenance of the PV array dimensions, that is; no module is removed or added to the array.

Furthermore, the control algorithm is based on the Rough Sets Theory, which allows the fast and efficient implementation of a control system, comprising rules that identify the system optimal configuration.
