Design of Automatic Generation Control for Multi-Area Interconnected Power system using FL-PID

Abstract

In this study, a hybrid Fuzzy logic-PID controller is used to design, model, simulate, and control the AGC of a four-area connected system. It was carried out in an effort to reduce the frequency, tie line power, and power angle variations brought on by shifting loads. Since the advanced values of the traditional regulator are permanent but static for load deviation, the FL-PID takes the place of the traditional PI and PID controllers in this system. Other methods have been created to solve the drawbacks of traditional controllers. The findings demonstrate how difficult it is to regulate frequency and power anomalies brought on by continuously fluctuating loads in the absence of a governor. When compared to the control approach employed in this study, the FL-only and FL-PI control method performs poorly dynamically, resulting in a significant amount of overshoot and a lengthy settling period, even if it offers 0% stability error frequency ,tie line power and load angle deviation in the system. The results demonstrate that FL-PID controllers were used to improve efficiency and prudently regulate the range of limitations to achieve actual power regulator, as opposed to FL and FL-PI control, which is done using Matlab.
