This article delves into SSCI impact on frequency stability, compliance, and the risk of operational curtailment due to power quality. As renewable energy resources expand, inverter-connected installations like Utility-Scale Wind Power Sites and Commercial Solar Energy Infrastructure bring a risk of sub-synchronous control interactions (SSCI). These low-frequency oscillations, arising from interactions between inverters and compensating devices, challenge grid stability and asset lifespan.
Harmonic impedance scanning is a powerful analytical technique used in electrical power systems to evaluate system behavior across a range of frequencies. This method is particularly useful for identifying resonance conditions and assessing the impact of harmonics on the quality of supply (Power Quality (PQ)).
