‘N^^N_NIL_3’ constraint equation

Bye X5, Hi X5

From 16th March 2023 the infamous ‘x5 constraint’ has been split into two. We quickly showed previously that the design of the Left Hand Side (LHS) does not vary. In today’s article, valued guest author Allan O’Neil takes a look at what is different.


Splitting the ‘X5 constraint’ into two … double trouble?

From 08:00 (NEM time) this morning, the old ‘X5 constraint’ (i.e. formerly formally known as ‘N^^N_NIL_3’) has been split into two (i.e. addressing separately risk of tripping of either/both Bendigo to Kerang 220kV line and Bendigo to Shepparton 220kV line). Here’s a first quick look…
