The AGC performance is compared with intelligent fuzzy logic control with conventional controllers like PI, PID and PR under step load Disturbance. The conventional controller Gains for PI and PID(kp, ki,kd) is obtained by analyzing the transfer function using Ziegler Nicholas Methods. The intelligent fuzzy controller simulation is run to observe the performance of the system During 1% step load disturbance. The simulation result show that the fuzzy controller is better than the conventional PI, PID and PR controllers in terms of Better Dynamic response and steady error.

Optimizing the AGC system of a three-unequal-area hydrothermal system based on evolutionary algorithms
This paper focuses on expanding and evaluating an automatic generation control (AGC) system of a hydrothermal system by modelling the appropriate generation rate constraints to operate practically in an economic manner. The hydro area is considered with an electric governor and the thermal area is modelled with a reheat turbine. Furthermore, the integral controllers and electri...
متن کاملLoad frequency control of two-area interconnected power system using fuzzy logic control approach
Power systems are composed of power units that are constantly connected to each other and the electric power flux is constantly moving between them. All systems must be implemented in such a way that not only under normal conditions but also unwanted inputs or disturbances, are applied. It also remains stable or returns to a stable name at the earliest possible time. The fundamental factors...

The study of the battery charge process as the only power storage agent in off-grid systems is of significant importance. The battery charge process has different modes, and the battery in these modes is dependent on the amount of charge. In order to charge the battery in off-grid systems, two charge controllers including Pulse Width Modulation (PWM) and Maximum Power Point Tracker (MPPT) are c...

In this paper, load frequency control in two-area multiunits interconnected hydro thermal power system has been investigated. When an interconnected power system is subjected to heavy load disturbances, the system frequency and tie-line power flow are disturbed which leads to system instability. To stabilize the system frequency oscillations and tie line power flow variations, a PID controller ...
