Testbench for evaluations of maximum power point tracking algorithms for solar energy harvesting

In this paper, a simple testbench is presented for quick evaluation and comparison of maximum power point tracking (MPPT) algorithms. As a large variety of MPPT algorithms appeared and spread in the last two decades, it is necessary to provide quick and relevant means of fair comparison. Thus a testbench and its MATLAB/Simulink implementation are proposed and described. In this testbench two MPPT algorithms are compared: the widespread Perturb and Observe and one based on fuzzy logic. The testbench evaluates their convergence rate, tracking capability and steady state error.
