Electrical master planning for the fourth industrial revolution

Smart cities, driven by the fourth industrial revolution (4th IR), seems to be the buzzword in infrastructure development and procurement today – but what informs these decisions, and are we making smart ones? Existing methodologies are outdated and not sufficient to address long-term planning for the ever-changing power system. A modern methodology for developing a […]

Connecting world’s largest offshore wind farm to the grid

ABB has been selected by energy companies SSE Renewables of the UK and Equinor of Norway to supply its high-voltage direct current (HVDC) Light converter systems to connect the world’s largest offshore wind farms in the Dogger Bank region of the North Sea to the UK electricity transmission network. In the first ever use of […]

Embedded generation adds value to municipal grids

Microgrids and distributed energy resources (DERs) represent the grid of the future. So says Schneider Electric’s Poonam Lutchman. Speaking at the recent AMEU Convention in Cape Town, Lutchman said that municipalities need to become autonomous and secure sustainable revenue by getting ready for DER. The integration of DERs into grids makes these grids more complex […]

Deep disparities in the global energy system

Deep disparities define today’s energy world: The dissonance between well-supplied oil markets and growing geopolitical tensions and uncertainties; the gap between the ever-higher amounts of greenhouse gas emissions being produced and the insufficiency of stated policies to curb those emissions in line with international climate targets; the gap between the promise of energy for all […]

Choosing a variable frequency drive or soft starter

When accelerating an AC motor to full speed using a full voltage connection, a large inrush current may be required. Additionally, the torque of the AC motor is mostly uncontrolled and can shock the connected equipment, potentially causing damage. Variable frequency drives and reduced voltage soft starters can reduce inrush currents and limit torque thereby […]

The digitalisation of PV operations

All eyes are on digital technology as European PV plant operators continue to seek meaningful reductions in asset management and operations and maintenance (O&M) costs. Digitalisation promises to slash operational expenses and boost efficiency by automating many tasks that currently have to be done by hand, and by improving asset managers’ ability to rapidly identify […]
