Optimized Blade Angle Controller to Enhance Wind Speed Variability Impacts

Abstract

—This paper discusses the negative impact of wind farm penetration on the grid. This bad impact in this study is caused by wind farms due to wind speed variability. As wind turbines depend on wind speed to capture energy, this wind energy is assumed to be unpredicted due to the stochastic nature of wind. The paper focuses on that problem, wind speed variability, showing the most common solutions to overcome it. The paper presents pitch angle control as one of the most practical techniques experienced to overcome the wind speed variability challenge. Also, it illustrates the PID controller based on both Harmony Search Optimization and Whale Optimization Algorithms. First, the paper compares the effect of applying optimized PID control on blade angles with both HSA and WOA in one season of the year. Then; it studies the most effective algorithm among them and applies it to the rest of the year seasons.
