Power system transient stabilization and voltage regulation based on simple neuron structure

A global power system transient stabilizer and voltage regulator based on a simple neuron structure is proposed in this paper. Two independent controllers i.e. transient controller and voltage regulator are designed. To this end, a simple structure controller that consists of only one neuron is used. The proposed neuro-controller does not need any offline training and the parameters can be determined on-line. To achieve the global control action that guarantees both transient stability and voltage regulation, we used a membership function that was a function of measurable parameters of the system. The proposed global control law acts in a manner in which in the transient period, the transient stabilizer is the dominant controller and in the post transient period, the voltage controller is the dominant one. The effectiveness of the proposed global control action is demonstrated through some computer simulations on a single machine infinite-bus (SMIB) power system.
