Abstract

In order to study the influence of system parameters on the stability and dynamic performance of combination-configuration microgrid based on droop control, small-signal model is established at the point of steady state. By calculating the eigenvalues of state matrix, the small-signal stability of combination-configuration microgrid can be directly analyzed. Based on sensitivity analysis, the key parameters influencing on each eigenvalue are found out. Using root locus method, the ranges of key parameters and their influence on dynamic performance are determined. Analysis result shows the presented method provides the basis for the optimization design of key parameters, and is helpful to improve the stability and dynamics performance of islanding microgrid.
