  • 摘要:

    In this paper a new robust load frequency controller for two area interconnected power system is presented to quench the deviations in frequency and tie line power due to different load disturbances. The dynamic model of the interconnected power system is developed without the integral control. The area control error is also not included. The frequency and derivatives are zero under normal operation and after the disturbance effects are died. Then the problem is restructured as the problem of state transfer from the initial steady state to final steady state without oscillations in less time. The Genetic algorithm (GA) controller designed here consists of two crisp inputs namely deviation of frequency and the other is derivative of frequency deviation. The output of the Genetic algorithm controller is the control input to each area. The studies power system is subjected to a wide range of load disturbances to validate the effective ness of the proposed Genetic algorithm controller. The simulated results are obtained for different configurations of the Genetic algorithm controller like placing in area 1 only and placing area 1 and area 2 for different options of load variations. The digital results prove the present Genetic algorithm controller over the other control studies presented in earlier work in terms of fast response (dead beat response for certain configuration of Genetic algorithm controller) with very less undershoots and negligible overshoot with having small state transfer time to reach the final steady state with zero frequency.
