Design and Simulation of 500kw Wind-solar Complementary Microgrid

This Faced with the energy and environmental problems facing the world today, renewable energy with many advantages has gradually entered people's field of vision. Among them, solar energy and wind energy are the most prominent. Wind and solar power supply can solve the problem of electricity use in remote areas and improve. The environment has an important impact on further improving China's energy structure.This paper is mainly to simulate the wind power part and photovoltaic part and maximum power tracking in 500kw wind-solar complementary microgrid system, and explain the development of renewable energy; the basic concept and significance of micro-grid; Detailed description of the distribution of wind energy and solar energy resources, wind energy and solar energy in China; a brief introduction to the research status of wind and solar complementation; the system introduces the working characteristics and principles of wind turbines, photovoltaic cells and batteries; for wind turbines and photovoltaic cells The maximum power tracking control of the wind and solar hybrid system is described in detail.Finally, use Matlab/Simulink to build the corresponding maximum power tracking model, fan model, photovoltaic model, etc., and simulate it. The final result shows that the wind-solar complementary microgrid system designed in this paper can reach the maximum under standard test conditions. Power, changing conditions can also react quickly for maximum power tracking.
