Horizontal Axis Wind Turbine MPPT Control Research

摘要

With its clean, low cost and inexhaustible advantages, wind energy has become one of the fastest growing energy sources in the world. However, the low energy density of wind energy and its randomness and instability characteristics have brought many problems to the use of wind energy. Therefore, it is particularly important to the study the Maximum Power Point Tracking (MPPT) algorithm to improve the wind energy conversion rate of wind power generation systems. This paper summarizes the current research status of wind power maximum power tracking, summarizes the control characteristics and deficiencies of different control methods. At the same time, hydrogen energy storage and a generation system are added to the wind power generation system to improve the wind power's dissipation capacity, and the surplus wind power that cannot be absorbed by the power grid is stored by hydrogen electrolysis to produce hydrogen, thereby improving the wind power utilization rate. The simulation analysis of wind power system, maximum power tracking system, hydrogen energy storage system is performed in MATLAB / Simulink simulation platform.
