A high emergence of wind energy into the electricity market needs a parallel efficient advance of wind power forecasting models. Determining optimal specific speed and drive-train ratio is crucial to describe, comprehend and optimize the coupling design between a wind turbine-rotor and an electric generator (EG) to capture maximum output power from the wind. The selection of the specific design speed to drive a generator is limited. It varies from (1-4) for vertical axis wind turbines and (6-8) for horizontal axis wind turbines. Typically, the solution is an iterative procedure, for selecting the adequate multiplier ratio giving the output power curve. The latter must be relatively appreciated to inlet and nominal rated wind speeds. However, instead of this tedious and costly method, in the present paper we are developing a novel heuristic coupling approach, which is economical, easy to describe and applicable for all types of variable speed wind turbines (VSWTs). The principle method is based on the fact that the mechanical power needed of the wind turbine (WT) to drive the EG must be permanently closer to the maximum mechanical power generated by the (WT).

This paper analyzes the operating characteristics of wind turbine and introduces the principle of maximum power point tracking control system of variable speed wind turbine. A improved maximum power tracking control strategy is proposed for large inertia wind power systems in order to achieve maximum wind power capture and increased utilization of wind energy when wind turbines is below the rated wind speed. A variable speed wind power generation system is modeled and simulated in the Simulink environment of the Matlab .The simulation results proves the correctness and feasibility of the tracking control strategy suggested in this paper.

Horizontal Axis Wind Turbines

Wind power has many benefits over other energy sources, including a high power density and an outstanding return on investment. However, there are some drawbacks, such as intermittent output power and the need for periodic maintenance. As a result, its output is substantially variable, making it difficult to predict and potentially causing system instability. Therefore, to model such a source, it is necessary to model the dynamic behavior of the wind turbine generator as well as the characteristics of the wind speed to capture the fluctuations. Furthermore, the durability and efficiency of the wind energy conversion system (WECS) are wholly dependent on the quality of the control strategy employed. In this paper, we introduced a control scheme, which makes it possible to find an optimal solution to the control problem while at the same time operating within the constraint point. Therefore, we designed the Model Predictive Controller to control and smoothly transition the wind turbine in all its operating modes while complying with its constraints. The main objective of using this control technique is to maximize power production while keeping the control action as simple as possible. The WECS used in this study is the horizontal axis wind turbines (HAWT), which are easier to control as their dynamics are not so complicated to model and, at the same time, produce maximum output power. The controller works have to adapt in the same way as the control goals are different for different wind speeds. Gain and weight scheduling strategies are used to design a control system that allows smooth transitioning between control regions. The dynamics of the wind turbine system and the controller are designed and simulated by the MATLAB / Simulink environment.

Horizontal Axis Wind Turbine

This study is aimed to optimize the conversion of kinetic wind energy into electrical energy. Wind energy is a sustainable energy that is preferred to generate electricity for its low generation cost and low CO2 emissions. The considerations of physical principles of a horizontal axis wind turbine were involved in the study. Controlling of the blade angle deviation and the turbine rotation direction was also considered. For this purpose, a complete wind turbine system was setup by using the computerized simulation software (PSCAD). The system was running at five different cases with different wind speeds and different angles of the blade. The system was successfully generating a maximum output power from the wind turbine based on the changing of the deflection angle of the blade. Also the system would shut down if there were no matching between the wind speed and its direction with the angle of the blade.
