Tackling Sub-Synchronous Control Interactions: Ensuring Grid Stability in the Era of Renewable Energy Integration

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)).

Synchro-Waveforms: The Future of Power Systems Data Analytics

The Synchro-Waveform (a.k.a. synchronous waveforms) paper by Hamed Mohsenian-Rad and Wilsun Xu, both IEEE Fellows shows how synchro-waveform monitoring is a useful tool for power engineers. It discusses the latest developments in synchro waveform technology, power system stability, and energy economy. This paper goes over the basics of synchro waveform analysis, real-time power system monitoring, and techniques for synchronising large-scale power networks.

Puerto Rico as a warning to power grid operators

Rooftop solar is already South Australia’s largest electricity generator with about 1300 megawatts of capacity involving one in every three homes. A full picture of the grid, as it stands, is the precursor to a successful transition to a resilient, distributed grid architecture. Policy makers need to give engineers the data they need if they are to expect a successful transition.
