Abstract

In the recent years, the issue of the impact of wind farms integration to power system small-signal stability (SSS) has become a topic of increased interest and discussion. Results of SSS analysis of a power system of Bosnia and Herzegovina (BiH) for the base case (system without wind farms connected) and the case with 4 wind farms connected were summarized in this paper. Doubly-fed induction generator (DFIG) and direct drive synchronous generator (DDSG) wind turbine models are used. Analyses are done by computing the eigenvalues of state matrix of the power system around a stable operating point in order to determine the small-signal angular stability of the system with and without WFs connected. Also, three phase short circuits are simulated in two points in the system, with duration of 0.04 [s], in both cases. The power system models in this paper were all built using SIMULINK and the specialized application PSAT (Power System Analysis Toolbox) ver 2.1.10, a software application performed for MATLAB, which performs both, the numerical simulations and linearised eigenstructure analysis. The system responce to small disturbances for the base case (Case A) is compared to the case with WF models (Case B), and conclusions have been made in terms of the effect of addition of the wind farms (WF) into power system on the small-signal angular stability.
