Scanning through the article, the idea is to use a ripple frequency controller to shut off power from people’s solar system. If you have a battery system tough luck, you can’t charge your batteries or run anything else.

The knock on effect will be as the controller switches off solar power at your house, all the things at your house using solar power will now have to draw power from the grid so you might have widespread black outs.

The QLD power authority has decided to act unilaterally and its happening ( lucky there’s no government to stop them). I’m getting more batteries and will replace my gas hot water with heat pumps.

At the moment it will only be new installations or existing systems that are being upgraded so it shouldn’t affect me.

Switching control using Zellwegger tones has been around since mid last century but just because a technology is old doesn’t make it useless. A coded sequence of tones, about 1 kHz, is sent down the line and a relay at the other end interprets what action to take. Used in shedloads of electric water systems to take advantage of off-peak electricity. How that is going to add $300 to $1000 to a system cost seems a bit of cough bullshit cough to me.

Also, the new rules only applies to systems above 10 kW which will exclude the vast majority of suburban homes.

read that, I guess this is in response to high solar output messing with the usual line sag (dynamic regulation) that’s compensated for at substations I suppose, and the load for generators gets so small that it messes with what generator capacity you need online to maintain reliable supply (and efficiency related)

I mean if solar output goes up to supply nearly 100% of loads (for example) then the generator voltage minus the usual line voltage sag (loading) is going to be pushing up the line voltage

The major issue is grid stability. With the old sources of power generation came the added benefit of lots of inertia with large rotating masses. The grid jumping around with load changes was dampened by this large inertia. You don’t get that with solar inverters. if they become a large proportion of the supplied energy then step changes in load may cause a catastrophic cascading failure.

Baby steps

I grabbed a ripple frequency and made a little demonstration unit whilst an apprentice.

One controller

Two light bulbs

The first bulb came on at 11pm, the second at 11.30pm

I’d sat the controller isn’t that cheap AND it takes time to install it.

A good way to control solar output is to encourage people to install large hot water systems, the solar systems of Australia are used to heat water

You use the EXISTING ripple frequency controller to heat water when solar power is dumping power to the grid.

By encouraging people to heat water the cost of load balancing is shifted to the customer, you use existing controllers to control power usage. You encourage everyone to buy LARGE hot water tanks. When solar output is too great you start switching on power to the hot water system.

should have gone thorium

or tweaking phase relationship

You control a large LOAD to control the power grid.

That’s hard

The only way of creating a truly balanced load is to have black box that’s connected to all three phases ie you run 3 phase to the house and a black box provides power to the house maybe AFTER the service fuse.

Tweaking the phase relationship is exactly how every inverter operates to feed power to the grid, so not that difficult at all.

I meant the locking or synchronization between the power station and the inverter systems on the grid

Years ago as an apprentice they foolishly allowed me to sit in on a meeting talking about a new idea that was in its advanced stages of being implemented ( within months). The idea was the power authority would turn up and VISUALLY inspect the residence and give it the OK that everything was OK.

After listening to everything I pointed out that electrical installations can’t be tested “visually” and if someone’s house burnt down a week later after being given this bill of health the power authority would be sued / current affair.

There was a silence – I never heard of it again.

No idea

I figured that there would be existing technology though

Maybe that’s the answer

Change the nature of the load

Make a load that has the capacity to increase or decrease at will and balance the load on the phases. This expense would need to be at the customer side

Existing solar inverters already do this. They synch with the existing frequency

As much as I hate to admit it I’m glad you are here to put the correct information down.

Realistically this can only be done with NEW estates

By all means go back to all the older suburbs but it will be a draining experience

All new estates have the phase / load balancing equipment installed from new , in a new house.

At the same place I had one expert telling me the earthing system was never the metallic water pipes and refused to believe me until it was gently explained otherwise by another tech

( before we used earth electrodes the existing water pipes – the incoming pipe was OK to use as an earth electrode. After we started using electrodes, the water pipe was still connected but technically was part of equipotential bonding rather than the main official connection to earth)

With the gas heater gone the house energy requirements at least will be close carbon neutral

I’m still waiting for the next deadly hailstorm.

A hailstorm in Sydney in 1976 did $40 million in insured damage, which was a world record at the time. In 1986 it had a hail damage bill of $161 million. In 1991 it was $670 million. In 1999 it was $1.7 billion in damage with hailstones up to 9 cm in diameter.

A deadly hailstorm is not only overdue in Sydney, it’s overdue in most other capital cities as well.

It has never bothered you before.

Turns out this isn’t new

For rooftop solar households in the state, this means that all new or upgraded solar systems (with inverter capacity 5kW and below) installed on the state’s main grid, the South West Interconnected System, will be required to have the capability to be remotely switched off, and back on again, starting from Monday
