Insight into Your Electricity Power Grid at your Fingertips
By Phil Kreveld The brave new world of 50% power plus penetration of renewables in traditional AC grids requires reimagining legacy engineering and above all, a millisecond, synchronised view of network events. Synchronous generation is making way for asynchronous power generators, which connect via inverter-based resources (IBR). The inbuilt capacity for reactive power of synchronous …
No Renewable Systems without Millisecond MonitoringRead More
by Phil Kreveld Australia is leading the way in the quest for a renewable electricity grid. Being at the forefront comes with its challenges — the most pressing of which is maintaining network stability. This in light of a reduction in baseload and a reduction in traditional generation that supplies a stable voltage and frequency. …
Obvious Solutions for Grid Stability during the Renewable Energy TransitionRead More
“There was grid stability in the past, we still have it mainly now, and of course we’ll have it in the future”. That statement is heard often enough. “As the generator and load buses become more ‘dynamic’, we’ll adapt the grids organically—we’ll do whatever needs to be done to keep the system stable as there …
How the current crisis could hail a new era in renewable energy, and the dangers that come with it. Author: Dave Jones My analysis for Carbon Brief shows that electricity demand in Europe has fallen by 14% as a result of the crisis, with most major economies imposing widespread restrictions. This has resulted in lower …

Why the solar-powered grid needs to smarten up to meet the challenges of the COVID-19 pandemic. Western Australia’s Distributed Energy Resources (DER) Roadmap puts the region out front in the race to achieve a grid primarily powered by the sun. Described by an energy expert as a ‘laboratory experiment in the uptake of solar’, the …

Power transformers require consistent testing and maintenance to assess their condition and to uncover the issues that threaten the network. Maintenance engineers are a critical link in building power grid resilience and stability. A range of tools and technologies exist to assist engineers in their quest, with most investigations requiring a combination of devices to …
Overcoming the limitations of Power Quality Field Investigation with OTELLORead More
At 8:15am on 9 December 2017 the Gauteng suburb of Boksburg was rocked by a double explosion that shattered windows half a kilometer away. Almost immediately a column of black smoke rose into the sky and a rolling blackout left 25,000 households without power.
The importance of reliable, high-quality electrical power continues to grow as society becomes ever more reliant on digital circuitry for everything from e-commerce to industrial process controllers to the onboard circuitry in toasters and televisions.
With this shift to a digital society, business activities have become increasingly sensitive to disturbances in the power supply. Such disturbances not only include power outages (the complete absence of voltage, whether for a fraction of a second or several hours), but also power quality phenomena (all other deviations from perfect power, including voltage sags, surges, transients, and harmonics).
