Solar farms, wind farms and batteries in Australia’s National Electricity Market (NEM) meet the grid at a connection point. Four kinds of people answer for
As power systems evolve towards higher renewable energy (RE) penetration, engineers are increasingly encountering oscillatory phenomena that don’t fit traditional mental models. One particularly interesting
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)).
