DIgSILENT Pacific Presents At The IEEE Power And Energy Society For APPEEC

IEEE Power and Energy Society (PES) Queensland chapter successfully organised a large-scale, international power electrical engineering conference for the Asia Pacific region in Brisbane, Australia in mid-November 2015.

The APPEEC (Asia-Pacific Power and Energy Engineering Conference) 2015 attracted a large number of registrations and paper submissions from Australia, China, and also countries outside the Asia Pacific region including USA and South Africa. The conference attracted a good distribution of paper submissions from students, academics and industry representatives.

As part of DIgSILENT Pacific’s commitment to the power engineering industry, we took the opportunity to participate, and presented three papers:

  • Meeting New Distribution Power System Challenges, presented by Levin Mardira.
  • Sensitivtity Studies and Calibration of Small Signal Models, presented by Joseph Leung.
  • Small Signal Sensitivity Technique for Determining Interconnector Transfer Limits, presented by Joseph Leung.

The latter two papers demonstrate the level of expertise of the DIgSILENT group and its tangible experience in the transmission system analysis. Two of the papers are part of Joseph’s ongoing work in analysing the small-signal oscillation modes and its impacts in the transfer capability of Queensland and New South Wales Interconnector (QNI).

The paper ‘Meeting New Distribution Power System Challenges’ demonstrates how modern power system analysis tools, such as PowerFactory, would help distribution utilities in meeting the challenges of the ever changing distribution power system. The rapid changes in renewables and storage technologies increased the complexity in modelling and the operation of distribution systems. Considering also the demand to accurately model power system element behaviours such as the assessment of the dynamic responses of the solar PV and battery inverters in conducting grid connection studies for large scale renewable plants, DIgSILENT Pacific took this opportunity to share the expertise in power system modelling using three recent projects undertaken in Australia and Europe.

The three papers were well received by the audience, and Joseph and Levin had the opportunity to discuss further the contents of the papers with the academics and industry representatives in the paper/poster forum following the four-minute pitch sessions.

The three papers can be accessed through the IEEE Xplore online portal.
