Wind energy is inexhaustible nature of a renewable clean energy. Scientific, rational and effective use of wind energy has important ecological and economic value, is an important issue of China’s national economy in transition. However, due to the wind by a variety of factors of weather, terrain and season, the use of electricity from the wind with a lot of randomness and volatility, unstable power output, power quality is poor, this energy and power generation will power grid caused a great deal of impact is not directly grid for users, it is this volatility of wind power, which directly affect the large-scale application of wind power. To solve this problem, it is necessary to find a way to stabilize fluctuations in wind energy.This paper presents a new type of large-scale feng shui and solar power generation technology. Storage of water to replace the battery energy storage for wind energy, wind energy, the excess energy water can be temporarily stored when wind energy is small, the stored water can is converted into electrical energy, the formation of wind hydro and solar power generation, stable power will eventually be conveyed to the user. In order to meet the output power of the wind hydro and solar power generation system is almost constant and the use of fuzzy control technology.Using wind speed data to the Weibull probability density function fitting and in MATLAB structures Weibull distribution model, the establishment of wind power generation subsystem; established the fuzzy interface and fuzzy rules, and then integrated within the MATLAB integration of fuzzy inference and clear interface algorithm fuzzy control module; and water storage part of the relevant integral simplifies and feng shui hybrid generating fuzzy control system model, and finally Simulink toolbox in MATLAB software of the system was built imitate true, and achieved good results. Simulation results show that wind hydro and solar power generation system based on fuzzy controller can be a good solution to the problem of large wind power volatility, able to solve the difficulties of cross-regional large-scale the wind and water complementary power control for large-scale application of wind power provides a feasible solutions.
