Abstract: A simple and computationally efficient de-centralized control design method is given for load frequency control in the interconnected power systems. This de-centralized scheme comprises of a reduced order observer and a proportional plus integral controller in each area of the power system. It ensures zero static change in area-frequency and tie-line power. Some of the features of the de-centralized scheme are de-centralized implementation of a wide choice of feedback controllers, which have been designed off-line to meet the requirement of the global system and there is no need for inter-area transfer of data, for the purpose of load frequency control. The de-centralized controls are tested on computer-base simulation of two area interconnected power system. The simulated responses show that the de-centralized control scheme gives the satisfactory performance similar to centralized control scheme.
