Resumo
Finding the maximum power point (MPP) of a
photovoltaic (PV) system and staying close to it requires more
effort, since PV panels are often subjected to partial shading.
When this occurs, several local maxima appear on the P-V
curve, and algorithms based on local search, such as perturb
and observe (P&O) and incremental conductance (INC), are
unable to reach this point. For this type of application, global
maximum power point tracking (MPPT) algorithms are used,
such as the particle swarm optimization (PSO) technique, but
they present their difficulties. A hybrid approach using a
global search technique and a local search technique solves this
previous problem. This work proposes a hybrid MPPT, mixing
P&O and PSO techniques, applied to a two-switch buck-boost
(TSBB) DC-DC converter connected to a PV panel subject to
shading conditions. Simulation results, using PSIM software,
are presented in order to show the effectiveness of this proposal.
In this case, tests are performed to demonstrate the correct
functioning of the proposed algorithm
