摘要

With the complementary characteristics between wind and photovoltaic, wind-solar hybrid generating system take advantage of the intervals wind and photovoltaic to make the stable technology output by the control strategy of transformation, charging and storage and so on. For making maximum use of the wind and solar energy, this paper apply the Maximum Power Point Tracking control method to the global power of the wind-solar hybrid generating system according to the basic principle of the variable step perturbation tracking maximum power point algorithm. Due to the common DC/DC charging controlling unit adopted in the paper, both the whole circuit and control process are simplified to some extent. According to analyzing the mathematical models and the control strategies of the pv array, wind power generation and battery, the paper use the Simulink of the matlab software to simulate the whole Wind-solar Hybrid Generating System. The simulation results verify that the control strategy not only enable the system tracking the maximum power point very well, but bring about the little charging current float and rush.
