Marinus Link and the Rise of HVDC in Australia
The “Marinus Link” is a high voltage direct current electricity interconnector proposed for the purpose of connecting the Tasmania and Victoria grid systems. This project will feature the use of undersea and underground cables as long as several hundred kilometers. There will be a...

DER Integration & Renewable Oversupply Management
It should be noted that high penetration of rooftop solar strongly impacts the current flow through the distribution network. A traditional network predominantly involved unidirectional power current with power supply from central power stations down to consumers below. Additionally, with more energy produced compared...

MV Switchgear Modernisation – Sustainability, Digitisation, and Reliability in Evolving Distribution Networks
Historically, MV switchgear was fairly passive equipment. That is, once installed and commissioned, it would be expected to function reliably for decades without much human interaction except through periodic inspection and maintenance. Though adequate within a fairly stable grid dominated by large synchronous machines,...

Medium Voltage Drives and Industrial Electrification
Medium voltage drives are VFDs intended for use with medium voltage electrical power distribution systems. The drives are generally designed for use when the voltage is above one kilovolt. The main use of medium voltage drives is to control the speed and torque characteristics...

Renewable Energy Zones and High-Voltage Transmission Build-outs
Renewable energy zones demonstrate a move away from project-by-project connections to the grid and instead entail planning at the regional level. Presently, with project-by-project connections, each generator strives to connect to the grid, and REZs come up with areas with abundant renewable energy and...

System Strength and Voltage Stability in High-Inverter Power System
Large solar, wind farms, grid-scale batteries, and DER are now interconnecting within the National Electricity Market in volumes that have grown well beyond the retirement of conventional synchronous plants. Although the imperative of this change is core to the decarbonization imperative, as well as...

Grid Stability with High Renewable Penetration
“The pace of retirement of coal-fired plants, together with record levels of investment in wind, solar, storage, and transmission, is transforming the way the system is operated at its most fundamental level. Although this is necessary for decarbonization and the long-term affordability of energy,...

Grid Modernisation Challenges and Cost Pressures in Australia
Australia’s electricity grid is currently undertaking the most significant transformation since the creation of the National Electricity Market. Driven by the rapid exit of coal-fired generation, the growth of renewable energy zones, and rising electrification across transport and industry, the transmission network is being...
