Wind energy has emerged as a dominant alternative power generation source. Conventional energy resources are depleting and their increasing cost cannot be ignored. Wind energy has taken an important ...role in replacing fossil fuels and nuclear energy. However, optimal exploitation of wind energy systems has remained a thought-provoking problem due to the nonlinear behavior of the wind speed. Distribution generation system and isolated micro-grid (MG) are mainly used in a wind energy system in order to utilize maximum potential of wind through the maximum power tracking algorithm based on DC-DC boost power electronic converter. In this paper, authors propose a technique which is effectively workable, highly reliable, of low cost and induces less mechanical stress on the wind generator system (WGS). Experimental results of the proposed system verify that the effectiveness near optimal WGS output power increased approximately up to 50%. Thus, better exploitation of the available wind power is obtained under low wind speeds.
When compared with other renewable energy resources (RER), the wind energy share in the global energy production is increasing rapidly. Currently, the Government of Pakistan (GoP) is moving towards ...RER, specifically wind and solar energy. In this paper, the wind energy potential of Tando Ghulam Ali, Sindh, Pakistan is explored. For this purpose, one-year wind speed data is considered at various heights through various probability distribution functions (PDFs). Statistical comparison of Rayleigh, gamma, generalized extreme value (GEV) and lognormal PDFs have been done with two methods, namely root mean square error and (R^2) in order to select the best PDF. Results showed that the Rayleigh distribution function is the best at the above mentioned area for finding various factors like site selection and wind power cost per kWh.

Finally, it is designed and implemented on MATLAB/Simulink software to get optimum outcomes.
The development of wind generator dynamic model is of great interest nowadays. This manuscript presents the nonlinear characteristics of wind-generator system based on the squirrel cage rotor. The ...dynamic system becomes unstable due to uncertainty of wind speed circumstances. Therefore, a complete dynamic wind-generator modeling is carried out through the feedback control techniques, which plays a significant role in power system stability and control. The proposed control model consists of a 3-phase squirrel cage induction generator and implemented in the MATLAB software for the simulation in order to regulate the output parameters of the wind-turbine system. However, the proposed control design process has broadened prospectus of applications and developments. However, the simulation output response of proposed system yields a satisfactory performance.

Renewable energy integration has attracted widespread attention due to its zero fuel cost, cleanliness, availability, and ease of installation. Among various renewable energy sources, photovoltaic ...(PV) and wind turbines (WT) have become very attractive due to the abundant local availability in nature, technological progress, and economic benefits. The hybrid combination of both distributed energy resources eliminates mutual intermittences due to their adverse nature; therefore, the reliability of the system will be improved. The basic key objective of this project is to generate electrical energy by using renewable and clean energy with minimum pollution. We use a hybrid system to overcome the drawbacks of renewable free-standing generation system. The working model of the solar-wind hybrid energy generation system successfully operated. By considering the cost and effectiveness of the system, it is suggested for all the rural community members to use the solar-wind hybrid system for the generation of electricity.
The present paper formulates the state space modeling of doubly fed induction generator (DFIG) based wind turbine system for the purpose of the stability analysis. The objective of this study ...is to discuss the various modes of operation of the DFIG system under different operating conditions such as voltage sags with reference to variable wind speed and grid connection. The proposed control methodology exploits the potential of the DFIG scheme to avoid that grid voltage unbalances compromise the machine operation, and to compensate voltage unbalances at the point of common coupling (PCC), preventing adverse effects on loads connected next to the PCC. This methodology uses the rotor side converter (RSC) to control the stator current injected through the machine and the GSC to control the stator voltage to minimize the electromagnetic torque oscillations. Extensive simulation results on a 2MW DFIG wind turbine system illustrate the enhanced system performance and verify the effectiveness of the controller.
