The integration of large-scale wind generation has brought great challenges to the small-signal stability analysis of power systems, due to the output uncertainty of wind farms. To solve this problem, this paper extends the conventional concept of small-signal stability region (SSSR) to a concept of robust small-signal stability region (R-SSSR), which is capable of dealing with the effects of uncertain...
The interconnections and mutual impacts between the real-time market update process and the physical response of the power system will bring about new stability issue. This paper presents a more realistic discrete-time pricing model including congestion management, then models the coupling dynamics of the power systems and markets as a nonlinear hybrid system. And based on the locally sampling theorem,...
Droop-controlled distributed generation (DG) units are widely used in microgrids for rural electrification applications. In these microgrids, power quality is vulnerable to voltage and frequency instabilities due to limited generation capacities of DG units. More importantly, droop-controlled rotational and electronic DG units have different frequency dynamics, making a comprehensive stability analysis...
