The Impact

This paper uses the L indexes to analyze the impact of large-scale wind power penetration on the static voltage stability of the power system. First it presents some common indexes in analyzing voltage stability. Then, it introduces the principle of the L index. After that, Simulation based on the L Index of a typical power system interconnected with large-scaled wind power shows the grid alternatives have a considerable impact on the voltage stability. Finally it gives the conclusions.

Point Estimation Method

The static voltage stability of power system with wind farm is simulated by fuzzy simulation. This method is able to calculate not only the expectations and standard deviations of diagonal elements of Jacobian reduction matrix with the uncertain parameters but also the static voltage stability indicator based on the credibility theory. The method is characterized in that the impact of the assumptions of distribution function type of uncertain parameters and parametric statistics is avoided by this method. The calculated results are impacted only according to the actual changed range and the types of membership functions of uncertain parameters. Finally the calculation results based on that method are compared with the calculation results based on two-point estimation method and Monte Carlo simulation method. The results show that the superiority and accuracy based on the method is proved.
