This paper deals with a new method for eigenvalue region prediction of critical stability modes of power systems based on decision trees. The critical stability modes result from inter-area oscillations in large-scale interconnected power systems. The existing methods for eigenvalue computation are time-consuming and require the entire system model that includes an extensive number of states. However,...
This paper deals with the modelling of the wake effect in wind farms for use in dynamic power system simulation software. First, basic relationships describing the leeside wind speed as a function of the incoming wind speed under ideal conditions are put together. Through aerodynamic efficiency considerations the ideal power-coefficient of the turbine is then related to the actual power coefficient...
