<span lang="EN-US">In recent years, huge developments in wind energy production and meet consumer demand. Numerous researchers have focused on maximum energy generation techniques for the wind system. The main reason for this work is to compare the different smart controllers for the maximum power generation techniques in the wind system. In this article, we developed and modeled a 250-watt wind power system in a MATLAB environment and simulated it in different weather conditions. Based on the simulation results, two intelligent controllers, such as fuzzy and ANFIS, were proposed and compared to obtain the maximum energy generation techniques in the wind system. Finally, the optimal smart controller was chosen based on performance.</span>

The wind power generation system have strong nonlinear characteristics with many uncertain factors, which was hard to be controlled exactly by traditional controllers and the sliding mode control was proposed, the sliding surface was selected, the equivalent controller and sweithcing controller was designed. The wind power generation system was analyzed and the mathematical models of aerodynamics, drive train and electromagnetic subsystem were created. The control strategy was applied into wind power generation system with MATLAB/Simulink platform, and the simulation result shows this model is of more important significance on researching the power characteristic and control performance for power generation system, the sliding mode control with high power tracking performance, which can effectively implement maximum energy capture.

This article focuses on the topics of cascaded wind power generation system with Variable Speed Constant Frequency (VSCF). It consists of four key components, including the wind turbine, dual-rotor motors, low-speed synchronous motor and inverter. This paper summarizes and compares multiple topology form of cascade wind power system, and through the study of the relevant working mechanism, structure and layout of the form, the applicable conditions and scope of the new system are expounded in detail. In particular, as the superiority of cascade system, it makes a synthesis of variable speed and constant speed power generation into reality, thereby the cascaded systems comprehensive operational efficiency are improved.

Using renewable resources, such as solar and wind energy for generation presents technical challenges in producing continuous and controllable power. Since it is difficult to predict and control the output of the renewable resources, an extra Energy Storage System (ESS) is needed to enable a proper management of the uncertain power production. The ESS acts like an energy buffer such that the renewable output power can be regulated to suit the operational requirements of the network. To reduce the capital investment for the storage devices, it is important to estimate reasonable storage capacities. This report proposes an integration of solar and wind energy to form a hybrid power generation system. The goal is to reduce the capacity of the ESS so as to maximize the economic benefit that can be obtained from energy captured from the hybrid renewable sources. In the project, the studied hybrid solar-wind power system is compared with a solar power system and a wind power system. Results show that the proposed hybrid scheme is feasible to reduce the ESS capacity, by taking advantage of the complementary nature of solar vs. wind generation.

With the development of economy, the energy demand is becoming bigger and bigger, the development of wind energy is one of the main ways to solve energy crisis. In terms of energy utilization, high power wind power connected to the grid is currently one of the most effective ways of wind energy utilization. The wind power generation system connected to the grid plays the role of the changing wind energy into mechanical energy by wind turbines, and then converts mechanical energy into electrical energy by a generator. Because CSCF wind turbine works with the gearbox, which is low efficiency, noise and mechanical loss. And it has not been able to meet the needs of the times. Therefore, the direct drive wind power technology capable of tracking the maximal power point of wind power at rated wind speed has become one of the hot spots in the present research. This paper introduces the converter of the direct drive wind power system and analyzes the working principle of the direct driven permanent magnet synchronous wind power system.
