8:30 – 10:00 Panel: Modelling the AC-DC Hybrid Grid
Location: 405-460. Auckland University Faculty of Engineering, 20 Symonds Street, Auckland CBD, Auckland 1010
Theme EGrid Advances: Power Electronics in Transmission and Distribution
Overview of Panel: Discussion around developing a large-scale digital model encompassing DC grids and their interface to AC grids. They will enable operational steady-state, dynamic and transient studies associated with distributed power electronic converter interfaced technologies.

10:15 – 12:00 Panel: Topologies and Protection for Hybrid AC-DC Grid
Location: 405-460. Auckland University Faculty of Engineering, 20 Symonds Street, Auckland CBD, Auckland 1010
Theme EGrid Advances: Power Electronics in Transmission and Distribution
Overview of Panel: The AC circuit topologies, means the way things are connected to form a functional circuit, presently used worldwide have been developed and refined over many years. In this panel we will explore new DC and AC/DC circuit topologies. Some of the aspects worth considering are
- a) new ways of fault detection, location and isolation ensuring safety and minimising outage
- b) curtail DC egress into AC networks and, c) ways to ensure continued stable operation post fault isolation.
This panel will also explore implications of high level of infiltration of DC in AC systems and develop mitigation measures where needed. Furthermore, to enable progressive transition we will evaluate the potential of repurposing AC infrastructure for DC applications.

13:00 – 14:30 Panel: Enabling Technologies for Hybrid AC DC Grid
Location: 405-460. Auckland University Faculty of Engineering, 20 Symonds Street, Auckland CBD, Auckland 1010
Theme EGrid Advances: Power Electronics in Transmission and Distribution
Overview of Panel: The panel will discuss proliferation of DC grids within AC grids by addressing technologies and control mechanisms for different forms of power electronic converters:
- The DC networks are connected to AC via converter terminals that essentially convert AC power into DC power and vice versa.
- DC-DC converters enable change in DC voltage levels.
- Converters utilised in ancillary circuits are DC breakers using enabling technologies.
