| dc.description.abstract | This paper proposes a strategy for performance improvement of small-scale wind turbine
systems using maximum power point tracking control (MPPT). In this study, wind-turbine systems
which use permanent magnet synchronous generators and converter devices are modeled in
Simulink-Matlab software. In order to increase the power generated, MPPT is used based on
the extended perturb and observe (PO) method. This algorithm has the ability to improve the speed
of the turbine without oscillation. To analyze the ability of the PO-based MPPT in maximizing
output power, performance examination of wind turbine systems in Simulink-Matlab software was
conducted. The study is carried out with a 3000Wwind turbine device serving various electrical loads
of 50 W, 100 W, 200 W, and 300 W, and each ohm varies with a wind speed of 4, 5, 6.5, 7, 8.5, 9, and
10 m/s. The overall turbine system performance found that the maximum increase in system output
power occurs when it is loaded with 200 W with a wind speed of 6.5 m/s. During this combination of
200 W and 6.5 m/s, there are high increments of output power at 135.62% caused by the installation of
MPPT controllers, with an average output power increase of 50.77%. The results of this study proved
that PO-based MPPT has successfully improved the performance of wind-turbine systems. | en_US |
