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.
