Power System Security Assessment of the future National Electricity Market
The generation portfolios resulting from five
modelling scenarios have then been used as inputs to the University’s
assessment of power system security in the National Electricity Market (NEM).
Each of these scenarios features generation portfolios with increasing
penetration of Variable Renewable Electricity (VRE) sources out to 2050. Such
systems may raise security concerns since most VRE technologies do not
typically provide the so-called inertia, which has historically been one of the
main means of regulating the AC system frequency to (nominally) 50Hz.
