Abstract

This paper analyses the influence of intermittent wind power generation on the oscillation of a power system considering different load levels. The fluctuation in the eigenvalues and the eigenvectors resulting from intermittent wind power generation are calculated using Monte Carlo simulation with Latin hypercube sampling via modal analysis. An index known as “probability of stability” is used to determine the level of stability of the power system at different load levels due to variation in electromechanical modes resulting from changes in wind speeds. One of the key results shows that the load level of a power system has significant effects on the small signal stability of a power system consisting of wind generators. The result is validated using time domain simulation.
