Study the effect of partial shade on photovoltaic arrays with different connection topologies in MATLAB-Simulink

Abstract EN

In this paper, detailed studying of the effect of partial shade on photovoltaic (PV) arrays, which represent one of the most well-known problems that affect this field of renewable energy, due to that matter, this paper discusses this issue and makes a detailed discussion for different connection topologies that used to increase the efficiency of the PV system under partial shade.

This paper using MATLAB/Simulink to analyze three different connection topologies of PV modules under partial shade conditions (PSCs), these topologies are the series-parallel (SP) connection, total-cross-tie (TCT), and bridge linked (BL).

The results in the study help the workers in this field to choose the best connection topology for PV power system and reach to that; the TCT topology is the best
