Artificial Neural Network for coordinated control of STATCOM, generator excitation and tap changing transformer

Control of voltage in a power system under varying load conditions can be achieved by varying the generator excitation, changing the tap position of transformers and by varying the reactive power injection or absorption at the shunt compensated buses. Proper coordination of these controllers is essential for the effective operation of the power system. This paper deals with the development of Artificial Neural Network which gives the voltage controller settings, such that the voltage deviations at the load buses are minimum.
