Electric Power System Stability

I intend to do a few essays about electric power system stability.  I aim to share some concepts about power generation and grids, and in particular how electrical stability is achieved.

Some types of generation provide grid stability, other types undermine it.  Grid stability is an essential requirement for a power supply reliability and security.  However there is insufficient understanding of what grid stability is and the risk that exists if stability is undermined to the point of collapse.  Increasing grid instability will lead to power outages.  The stakes are very high.

I will discuss various engineering concepts with readers, and I’ll try to do it in a way that is accessible.   I’ll do my best to keep the discussion reasonably simple, sticking mainly to mechanical analogies rather than maths.

Here are some of the topics that I’ll be covering:

I aim to do one of these a week.

    And for amusement you might want to post statements by Tom Koutsantonis – SA Minister for Electricity (among other things) in chronological order.
    e.g. he didn’t know it was coming.
    Yes he did, but he was misled by public servant/ weather bureau/AEMO.

    The (mothballed CCGT plant with no fuel available) didn’t start up in 30 minutes but made excuses like “we don’t have any gas”, and “we can’t start up in less than 4 hours” – see their website).
    We must have the authority to order plants to start up.

    The closure of coal fired capacity won’t effect supply
    We need to spend $A500 million to fix the problem
    Which is not our fault etc.

    Looks very interesting and much needed for the energy supply debate…..I look forward to your posts

    Very interested ,this is the type of info we need to forward the debate.
