Abstract
In the society now, people pay more attention to the new energy, using the new energy can alleviate the current energy crisis effectively.Wind and solar power is a clean and convenient new energy sources, both of them have very strong complementary to each other in time and space, and their reserves is huge on earth.The use of solar and wind power is especially convenient in remote areas which the conventional grid cannot reach, such as mountains and islands, in this time we can make use of local abundant such as wind power and solar energy for its users provide cheap and friendly power resources . Therefore, more people pay more attention on the wind-light complementary system.
Through the access to relevant information,the design and research about the wind-light complementary system optimization is talked,on the basic of structure and working principle, it shows a deeply understand, including wind turbines, solar photovoltaic array battery, controller, inverter, and unloading bearing,the design of system is optinaled by using genetic algorithm,which improve the reliability of system and the effective utilization of energy, it shows the necessity of using algorithm to optimize system.At the same time, making modeling and simulation of wind-light complementary system with the Matlab to analysis operation and compare the waveform to know the importance of wind and solar energy complementary power generation.Finally combing the optimization scheme with the actual case, which ensure the power supply is stable and reliable, and make better for users, that realized the original target of wind-light complementary system optimization design, and increaseing the efficiency, saving construction cost and maintenance cost.
