The paper deals with the development of the dynamic model of wind by modeling the longitudinal component of wind speed. Statistical description of turbulent wind component using Kaimal’s function is represented. All necessary parameters for model performing are calculated. The results of modeling in the form of dynamic characteristics are presented.

The present work focuses on the development of control systems of wind-diesel power plant with DC-bus, which provide generation static stability for a given operation conditions. The article describes the operating modes of generating units and conversion devices, by which the maximum power output and static stability of the wind-diesel system are realized. Independent controllers setting for each generation source is proposed, making possible a modular extension of the hybrid power plant. The controllers are tuned for wind and diesel generation sources. Two optimization methods are used: linear and modular. By quality indicators analysis of the transients and logarithmic frequency responses the optimal structure and parameters of the regulators are selected. The regulators developed are implemented and used for existing power equipment. The control systems test experimental data obtained confirm the adequacy, reliability and performance of the developed solutions.
