Thread: Grid can go 75% renewable

Sticking storage in on every home would help - but the cost needs to come from somewhere and no one wants to pay for it.

Limiting solar output into the grid is sorta done naturally now by the inverters which won’t bring the voltage up higher than a certain point.

Not sure what the answer is, but I know how much it is causing issues for the grid - I work with that side of things a lot and the supply authorities are basically just treading water and doing what they can.

"Detailed review of energy applications and use cases such as P2P energy trading" Bock chain is I think a solution. Large storage via Hydrogen is likley to be a short/medium term option. pumped hydro and batteries are minnows really despite the hype and billions in them. Storage of stranded/wasted resources via Hydrogen - and fuel cell power generation is on a downward cost spiral.

Some of the idea in AEMO proposals are fair in some respects. ""It'll only happen when there is congestion on the network, not at all times when you're exporting into the grid," he said."


"A survey of the German Energy Agency [18] on the views of energy decision-makers shows that near 20% believe that blockchain technology is a game-changer for energy suppliers. The survey was based on the views of 70 executives working in the energy sector including utility companies, energy suppliers, network operators, generators and aggregators. More than half of survey participants plan or have already undertaken initiatives for blockchain innovation. Several energy utility companies have taken interest in exploring the potential benefits of distributed ledger technologies (DLT)," Link

The AEMO proposal is at one level normal business. Try selling tonnes of Icream at the beach in winter is possibly a example. the Same business might be flat out in summer.

"Not a one-size-fits-all systemMr Barr said power companies could create different services that allowed people to avoid charges altogether if they exported power to the grid when it was needed.
"If customers can move around when they're using electricity, or when their power comes into the grid, they could see a benefit," he said.
People could be slugged a fee if they export when the grid was busy, but Mr Barr insisted that would not be the default position."

Why should I be paid for energy if no one needs it at that time is a reasonable question.

It allows " Energy trading

Our platform's energy tracking and trading features can be used to give consumers choice over the energy they use and facilitate the trading of electricity peer to peer. Solar P2P energy trading can deal with excess solar in the grid without subsidy.

If you have solar panels on your rooftop you can use our platform to sell excess energy to your neighbor. When coupled with batteries and our VPP platform feature, surplus solar can be stored and sold at the peak to maximize profits.

Power Ledger's platform gives security and peace of mind, by recording all transactions on the blockchain.

It is must be that I am either a bit thick, or that every thing that I have been taught, and learnt, in running generators for more years than I want to remember, is just all wrong, or I maybe I am just dreaming!

WHY are all the "experts" blaming the "grid"? It would not matter if somehow the "grid" suddenly had another million miles of cabling strung all over the country! About the only truth the following talking head speaks is "the grid is designed to carry electricity from the producer to your home".

The "grid" is NOT a frigging battery, or any other device able to "store" electricity! It is not like a water tank where you can just add another tank to increase the capacity. Neither does it just "overflow" when too much energy attempts to get put on to it.
Sorry, it is beyond this old geezer!

Low-income families back proposed solar export fees in hope of reducing power bills

Low-income families back proposed solar export fees in hope of reducing power bills - ABC News

Low-income families have welcomed proposed changes that would see solar panel owners charged exporting fees in the hope of reducing the overall cost of electricity.

The real experts aren’t blaming the grid, they’re just trying to figure out how to make it cope with so much solar and wind connected to it.

Keyboard ‘experts’ are blaming the grid. 99.99% of the population have no idea how it operates, what issues over supply of renewables causes and why, understands the physics or maths behind it, even knows what a rotating magnetic field or magnetic rotor lock is when paralleling or have a clue how to fix any of its issues.

That won’t stop them from offering their opinions though. It’s just the way it is and one reason I’ve stopped posting in certain threads and areas as I’m sick of being told I’m wrong when I’ve been doing this for a living for decades.

I just take a deep breath and move on.

How do you arrive at this?

Well, I don't know just how an "expert" is defined:

Another option is to upgrade our electricity grid infrastructure, Dr Verbic said."If you replace the existing wires with thicker ones, the over-voltage is no longer an issue," he said." But reverse power can still be a problem. This can be dealt with by replacing protection systems in the transformers."

Solar splurge hits record highs in WA as COVID-19, downturn fails to quell demand

Solar splurge hits record highs in WA as COVID-19, downturn fails to quell demand - ABC News

WA households installed a record amount of solar power in 2020, further fuelling the rise of green energy in the country's sunniest state despite the economic downturn.

The splurge helped drive demand for electricity from the state's main grid to a new low as the ever-increasing amount of solar energy displaced coal and gas-fired plants and wind farms.

Figures from the West Australian government show about 300 megawatts of solar capacity was added to household rooftops last year.

The amount installed was the highest on record and almost amounted to the capacity of WA's single biggest coal-fired power plant, the 340MW Collie generator.

There are now 1.3 gigawatts' worth of small-scale solar systems in place across WA's biggest power grid, generating the equivalent of about one third of peak demand.
