Differential Evolution Based Optimal Tuning of Load Frequency Controller
Load Frequency Controllers (LFC) are required to maintain constant power and frequency in inter-connected power generating systems. Differential Evolution (DE) based optimal tuning of load frequency controller of two area inter-connected power system is presented in this paper. The proposed method optimizes the parameter of Integral controller by selecting the optimal gain which drives the change in frequency in the two areas and change in tie-line power flow to zero within the shortest time span. Simulation results on two networks revealed that the proposed controller dampened the frequency oscillations and restores the system frequency and tie-line power to set value after a step load disturbance.
