Oh and to complete the answer to the issue: Best way to solve this is de-centralized battery storage in the endpoints where the PV is installed to soak up the midday peak and release it when the home or the EV charger needs it. And of course, avoiding the local low voltage to be configured "hot" ac

Re: [EVDL] LIVE stream 8/31/21 1540 PST A physicist consultant to power utilities on how the EV mass adoption is affecting the

The ways that the grid can't handle the amount of PV generation is typically not on national grid scale or even regional grid, although that may theoretically happen when the transmission line capacity is reached. Most likely is a problem on local scale, where you have pole pigs (25kW) serving bloc

In today's local paper is an article about FlexGen in Durham NC, they're raised $150M. They build "software that helps grids manage energy storage." Doesn't sound exactly like market and also not hardware management software. " FlexGen's energy storage solutions bridge the gap of reliability for t

Here is the daily CAISO report. http://www.caiso.com/PublishedDocuments/WindSolarCurtailmentReport.pdf It shows that the vast majority of curtailment events is due to local system congestion, and not because of demand. I expect that remotely-positioned MW-scale solar farms are much more suscepti

Are you referring to the kind of metal tanks with roofs that change height? Or are you thinking of some kind of storage in giant low pressure balloons/gas bladders, on the ground, that are anchored to the ground? Giant low ground mounted pressure balloons may be a cost effective way to store huge

Batteries on a large scale fall behind H2 storage if you have big enough tanks, and if you correctly factor in the costs of batteries and tanks. Where the lines cross is an open question. I live 10 miles from a big gas depot in Selma NC. They hold lot and are very simple, big inverted buckets that

"that the grid can't handle" is just another example of market distortion. It is a choice of the market, not to say "the grid can't handle so much generation of non-RE." There is a lag in response of the market when you build a gas plant or a nuke that can't be turned down when the cost leans towa

google ducks-back-curve. Battery storage is max value for about 2 hrs a day during the evening demand as solar shuts down and baseload power ramps up. When the grid pays battery owners their actual rate during that peak need, a battery system can completely pay for itself in about 2 yeard. bob On

RE oversupply implies discounting RE power. Whatever distortions that are applied will have to be paid for, by customers probably, because stockholders are rarely penalized. It is also possible that RE power is actually less costly, then the penalty gets paid by the customers of the non-RE generat

We have a nation wide grid and a market for power. Storage is less of a problem than cost. CA may not be selling at a price people are buying. It's also hard to raise level of pump storage when the water gets used for ag. My first guess is CA has distorted the market with subsidies, etc. It is lik
