Abstract
A fast method based on the phase trajectory to compute DSR is developed. Firstly, the phase trajectory sensitivity has more linear effect than power angle sensitivity. According to the phase trajectory boundary function, controlling unstable equilibrium generators could be identified. The PDSR is finally obtained by the sensitivity analysis between the phase and generators’ active power. Test results on the New England 10-genrator 39-bus system are presented and prove the effectiveness of this approach.
