面向多时间尺度稳定性提升的构网型储能分层布点策略

This article proposes a hierarchical site selection framework of grid-forming energy storage (GFM-ESS) devices. This framework enhances stability of both the device itself and the power system across multi-timescales with respect to static, dynamic, and transient stability layouts. Specifically, the first layout optimizes static voltage stability margin and system losses. The second layout evaluates small-signal stability based on the generalized short-circuit ratio (gSCR). Finally, the third layout maximizes the GFM-ESS supporting performance in response to the system dynamics. A case study based on Western China serves to validate the effectiveness of the proposed GFM-ESS site selection strategy and to prove its scalability for large real-world power systems.
