The largescale integration of Power Electronic Converters (PEC) into many of today’s power networks is already causing significant system impacts. In the Australian NEM, Tasmania included, the uptake in Renewable Energy (RE) continues apace and presents escalating challenges in power system management.
In the past, HVDC systems represented by far the largest PEC connections to power grids and real time simulators were used to test them before grid connection was allowed. The management of modern grids, which now accommodate other large PEC sources such as solar and wind, will also benefit from the insights only possible with RTS.
TasNetworks recognised the high risk posed to its network by additional HVDC Interconnectors and has therefore invested in its own RTDS in readiness for their connection. Given the already high penetration of PEC in Tasmania, it has been necessary to develop a highly accurate RTDS model of the power system so that dependable “hardware-in-the-loop” testing of these future HVDC systems will be achievable.
This presentation will highlight the main challenges, developments, achievements and insights that TasNetworks has found on this journey so far.
