This paper explores the evolution of wind power plant (WPP) control strategies, from simple approaches aimed at optimizing the operation of individual wind turbines to the development of more complex systems that manage WPPs as single integrated entities. Particular attention is paid to the key requirements for WPP control systems and the analysis of WPP structure, especially in the context of their integration into the overall power system. The main objectives of WPP control systems have been studied.

The paper presents the results of the calculation of technical and economic performance of various wind farms WTG with wind turbines for the real wind conditions in Ukrainian Carpathian region to choose the optimal equipment.

The conditions of the point of common coupling choice of wind power plants are shown schematically and the conditions that must be met for their joint operation as a part of the power systems are described. The effects of integration of wind power plants into the power systems at the local and general levels are analyzed. The requirements of the international Grid Codes to the frequency control of the power systems with wind power plants are considered.

The paper presents the study results on renewable energy hybrid system within a micro grid which is tied to bulk power system. The voltage variations character has been analyzed considering mode of wind generator reactive power control. Optimal reactive power control requirements are shown in consideration of voltage variation mitigation.

The differential equation of wind-wheel rotational motion under the influence of aerodynamic and resistance moments was built on the basis of the simplified kinematic scheme of horizontal axis wind turbine and with the help of Lagrange second-order equations. The determination of motion parameters and the construction of appropriate time diagrams were realized taking into consideration time dependencies of wind-flow speed.
