Comparison of MPPT strategies for solar modules

Authors

The paper studies the behavior of three different

Maximum Power Point Tracking (MPPT) strategies applied to

solar modules: three-point perturb and observe, fixed-step

incremental conductance, and variable-step incremental

conductance.

It starts with a brief description of each method and then it

compares them considering three criteria: simplicity of

implementation, capability to follow irradiance variations and

sensitivity to noise in the required measurements. Diverse

simulations have been performed and the main results are

presented.
