Automatic Generation Control of Three Area Power Systems Using Ann Controllers

This paper presents the use of one of the methods of artificial intelligence to study the automatic generation control of interconnected power systems. In the given paper, a control line of track is established for interconnected three area thermal-thermal-thermal power system using generation rate constraints (GRC) & Artificial Neural Network (ANN). The proposed control has been designed for a three-area interconnected power system that two areas include steam turbines , artificial neural network (ANN) controller, which controls the inputs of each area in the power system together, is considered. The working of the controllers is simulated using MATLAB/SIMULINK package. The outputs using both controllers are compared and it is established that ANN based approach is better than GRC for 1% step load conditions. The performance of the power system is simulated by using GRC and ANN controller, separately. By comparing the results for both cases, the performance of ANN controller is better than GRC.
