Fast modelling with Real-Time Simulation

The increasing penetration of renewables has led to a rapid rise in the amount of power electronics connected to the grid. Renewable energy sources like solar, wind, and tidal power all connect to the grid via inverters. Of course, all the positive changes enabled by power electronics do not come without risk. Since power electronics have closed loop control systems there is potential for resonance to be amplified – and with so many power electronics in the system converting and controlling the flow of electricity, the potential system impact of harmonic resonance has grown dramatically. Making sure all the power electronics on your system work together properly is more important than ever before.

PSC supports commissioning of world’s first VSC Bipole HVDC link

HVDC’s ability to send large amounts of electricity over long distances with low electrical losses has historically made it a technology of choice for long-distance bulk power transmission. HVDC, particularly VSC (Voltage Source Converter) technology, is increasingly the method of choice for overcoming the challenges associated with accessing remote renewable energy resources that require subsea electrical transmission and the interconnection of asynchronous AC grids, providing efficient, stable transmission and control capability.

Power System Dynamics in Distribution Systems

Historically, in large electricity grids, generation is rarely found within the distribution system, but is rather connected remotely via a high voltage transmission network. With the trends seen in the transformation of the grid, generation embedded in the distribution system is now becoming the norm, rather than the exception, and can include wind, solar, and batteries, as well as conventional diesel and hydropower units.

Detailed Testing, Modelling and Compliance in the Snowy River Mountains

Snowy Hydro is a dynamic energy company supplying electricity to more than one million homes and businesses. Since the days of their pioneering past, Snowy Hydro has grown into the fourth largest player in the Australian energy market. Snowy Hydro not only operates the mighty Snowy Scheme (nine power stations including pumped storage at Tumut 3 Power Station and Jindabyne Pumping Station), it also operates gas and diesel peaking assets in New South Wales, Victoria and South Australia. They have a total generation capacity of 5,500 megawatts (MW) and offer energy insurance and other products that provide supply security and price certainty to customers in the energy market...

PSC Sponsors Electric Bicycle Competition

It has been a busy few months for a team of students at Scots College in Wellington New Zealand as they build an electric bicycle for the Evolocity electric vehicle school competition. The team’s electric bicycle recently competed in the Wellington regional competition in September.

The competition included several different courses and challenges for their bike to compete in as well as incorporating two technologies that improves the driving and control of their bike.  The team contacted PSC due to our involvement in EV vehicles and we are pleased to provide sponsorship for this project. The students have had to explore innovative ways to engineer the design, in a test of problemsolving, teamwork and skill.
