Distribution system multi-domain simulation tool for wind power analysis

Abstract

This paper develops an integrated multi-domain simulation tool for distribution systems designed specifically for applications in wind power analysis. The proposed tool consists of steady-state, electromechanical transient, and electromagnetic transient models of voltage sources, transmission lines, transformers, capacitor banks, fixed-speed wind turbines (FSWTs), and wide-slip wind turbines (WSWTs). The test circuit used to demonstrate the multi-domain simulation approach is the IEEE four-node test feeder with a wind turbine connected at the feeder end. The simulation is performed for a one-day period. During this period, wind speed changes every ten minutes, a capacitor is switched on and off, and a temporary single-line-to-ground fault occurs. The results show that the proposed multi-domain simulation tool is able to simulate and analyze long-term power system phenomena.
