Definition and Classification of Power System Stability - Revisited & Extended

Nikos Hatziargyriou et al.

Summary: Since 2004, the dynamic behavior of power systems has changed due to the increasing penetration of converter interfaced generation technologies, loads, and transmission devices. In response to this change, a Task Force was established in 2016 to re-examine and extend the classic definitions and classifications of basic stability terms to incorporate the effects of fast-response power electronic devices. This paper summarizes the major results of the Task Force's work and presents extended definitions and classifications of power system stability.

Modeling and Optimal Tuning of Hybrid ESS Supporting Fast Active Power Regulation of Fully Decoupled Wind Power Generators

Chenrui Zhang et al.

Summary: This paper investigates the improvement of frequency response of fully decoupled wind power generators by introducing ultracapacitors and hybrid energy storage systems in real-time simulations, and discusses the trade-off between frequency performance and cost through optimization. The results show that fast UC power injection enhances the frequency response speed, with virtual synchronous power providing faster frequency support compared to other control strategies.
