Abstract: Wind, as a green energy source, has been chosen as the major energy source for sustainable development in many countries. In Hong Kong, wind is also becoming an alternative energy source to fight against energy security and environment concerns. Research into the impact of increasing wind penetration on power system stability has drawn a major attention. The most obvious obstacle of wind utilization is that Wind Energy Conversion Systems (WECS) may need reactive power support to deal with voltage sag and rotor speed increase when being subject to a grid disturbance nearby. This unique characteristic must be pay attention to so as to achieve a large amount of wind power integration. This paper evaluates the dynamics of a WECS under a relatively new stability concept, rotor speed stability. With the assistant of preliminary application, a small case study has shown that dynamic reactive power compensation outperforms those self-regulated support, which to some extent illustrates that optimized integration of large amount of wind power into the existing power system could be assisted with by rotor speed stability analysis.
