Power Generation System

Due to the defect of the traditional wind power generation equipment, the hydraulic-type wind power generation (HWPG) system has gained extensive attention. In order to study the generating stability of the HWPG system, we established the mathematic model of the off-network HWPG system in this paper; and built its simulation model by using MATLAB/Simulink to investigate the speed and power of the system with the sinusoidal input signal. The simulation results show that the output electric energy of the hydraulic type wind power is unstable. Therefore, to enhance the practical application effects of the off-grid HWPG system, we have to add a storage equipment or speed controller of the motor to improve the quality of output electric energy.

Promising Source

The rising demands for a sustainable energy system have stimulated global interests in renewable energy sources. Wind is the fastest growing and promising source of renewable power generation globally. The inclusion of wind power into the electric grid can severely impact the monetary cost, stability and quality of the grid network due to the erratic nature of wind. Power electronics technology can enable optimum performance of the wind power generation system, transferring suitable and applicable energy to the electricity grid. Power electronics can be used for smooth transfer of wind energy to electricity grid but the technology for wind turbines is influenced by the type of generator employed, the energy demand and the grid requirements. This paper investigates the constraints and standards of wind energy conversion technology and the enabling power electronic technology for integration to electricity grid.

Step Climbing

Maximum power point tracking for wind power generation system fixed step climbing algorithm prone to miscalculation and oscillation shortcomings. Adaptive improved optimal gradient method is put forward to overcome the shortcomings and optimize the existing fixed step climbing algorithm. By Controlling Buck Converter duty radio rapidly match between wind power generation system and load impedance. The simulation result shows that the anti-interference and convergence of the improved hill-climb search algorithm is better than that of the traditional one.
