Automatic Load Frequency Control of Multi Area Power System using Hybrid Technique

In a two-area power system, with random change in load demand, the frequency varies. Load frequency control (LFC) is to minimize the transient variations and also to make sure that the steady state error is zero. To achieve this, automatic load frequency controlling strategies with Fuzzy-ANN controller are proposed. The Real time data used in this study collected from Southern Load dispatch Center, Power Grid corporation of India limited Bengaluru. The effectiveness of the controller are validated by performance parameter assessment. The development and simulation of power system components, test systems and proposed controller is modelled using MATLAB-SIMULINK Environment. The results found satisfactory and compared with other techniques.
