Power System State Estimation Containing Wind Generators

It is essential to investigate the effects which will produce on the power system when wind generators are introduced. The paper describes the steady model of wind turbines with an asynchronous generator. Based on the conventional RX model, power system state estimation containing wind generators is proposed. The slip of the asynchronous generator is utilized for the formation of expanded correction function in iterations. This method retains good convergence property as the traditional WLS method and also can be integrated to the conventional state estimation program with the consideration of wind generators. The simulation results demonstrate that the model is effective for practical use.
