HOME / Wind Power Prediction Based On Deep Learning Models - BeTheFuture Solar Foundation & Infrastructure
The PID (Proportional Integral Derivative) control model is the cornerstone of classical control theory, widely used for adjusting the pitch angle of wind turbines due to its simple structure, intuitive design, and ease of implementation.
Depending on historical signals from wind direction sensors, conventional yaw control methods provide general performance and may be optimized by taking advantage of wind direction prediction. This paper presents two wind direction prediction methods based on time series models.
Currently, almost all wind turbines use pitch control systems and yaw systems. The yaw drives control the alignment of the nacelle with the wind; the pitch control system is constantly adjusting the angle of attack of the rotor blades—the pitch angle—in order to achieve the greatest possible energy yield.
In order to effectively operate the yaw system of WT, a YS based on historical wind direction data and real-time wind direction prediction is proposed. After studying the wind direction variation characteristics and rules of WTs, the historical samples are analysed and combined with BPNN, and a wind direction prediction model is formed.
The implementation of this highly complex operation relies on multiple closed-loop control systems. Currently, almost all wind turbines use pitch control systems and yaw systems.
The pitch control system has been the gold standard for years when it comes to cost-efficient, robust rotor blade adjustment in wind turbines. In addition, the engineering design of the pitch systems can increase the availability of the wind turbines.
The pitch system regulates the power output of the wind turbine by adjusting the rotor blades; at the same time, it functions as the main brake. This is absolutely crucial for ensuring the greatest possible efficiency of the wind turbine and the highest possible energy yield.
While the initial investment in energy storage battery systems may be higher, they require no continuous fuel consumption and can last for more than 10 years, significantly lowering operational and maintenance costs over time.
