Battery Charging Control for Wind Energy Generation System

Abstract

Most variable speed wind turbines have pitch angle control

mechanisms and one of their objectives is to extract maximum power from

available wind speed, by adjusting pitch angles of wind turbine. In this

research, the use of pitch angle control using PI controller is presented for

wind turbines equipped for a three turbines with self-exited induction

generators (SEIGs). The converters are used to extract the maximum

available power from the wind. All machines are connected to a dc bus,

Also, a bidirectional buck-boost converter designed between dc link and

battery with fuzzy logic controller (FLC) to charge/discharge battery to

make uninterrupted feeding system and maintains constant DC link voltage

to make ability of feeding dc loads, and ac loads through the inverter. A

fuzzy logic-based controller is used to control the voltage of the proposed

system. The entire proposed system is modeled and simulated using

MATLAB/Simulink software.
