Storage can be part of supply, demand or even transmission and this matters greatly because where you put the storage also determines the regulations you have to follow. If you develop storage as supply you may end up in the regulatory regime for qualify facilities (Order 872) MISO, CAISO, & SPP are discussing "storage as transmission" - think of it like one of those zipper machines that...
Energy storage is pure energy conversion process. In one phase it is a demand, while in another it is production. Multi benefits have been provided through the process , the main is the storage of excess cheep energy , to utilized when it will be needed badly. Other byproducts are increasing resilience and robustness of the power systems.
Hi Eitan: My answer is that a definition does not really matter, Fundamentally, if we are going to put fossil fuels as an energy source to bed for good, there needs to be a massive amount of energy storage available. The solar and wind power options presently available are at best intermittent. To create a landscape of baseline dispatchable renewable energy, we are going to need to see...
Insights on how to integrate production, transmission and distribution systems with demand management?
Currently there is an array of design solutions on the demand side that can be applied to reduce the peak capacity (and energy) requirements from the grid.
It is hard to be effective , even in case it is achievable . The integrated power system ( generation , transmission and distribution) looks as The Central Bank of State , while all demands are spot markets of different goods. Does the fluctuations of some good prices affect the CB policies ?
I believe we manage the grid according to peak load because, in part, we are limited by the technology we have today. To manage against real-time demand, we would probably need: * Generation sources that can come line and go offline rapidly. Natural gas fired turbines cannot do this. Probably need storage with every generation source to do this.
What plans are being made to integrate load management with dynamic electric grid performance requirements?
Unfortunately the comments to this interesting question seem to follow the unfortunate, but typical path from online discussions of stating the opponent as more or less stupid and cause of all problems. The question and the challenges deserve better. No doubt, we're facing challenges with the implementing of non-controlable DER's and EV charging stations. But for a nation that is able to...
The grid problems are the result of too much erratic and unreliable energy being shoved into the grid. As the problem is caused by renewable energy, then renewable energy needs to solve the problem. Fundamentally, those who cause problems need to be responsible for fixing the problems they create. Somewhat annoying that the article holds those responsible as apparently blameless.
I would say that the grid will morph into a grid of microgrids, where the 110Vac/60Hz only exits locally, maybe only at the individual appliance level, the upper levels being (HV-)DC to maximize power throughput on the existing wires.

FERC's opt-out rule has created a stalemate for distributed energy resources and demand response programs
"A new standalone power system that produces energy with solar panels, batteries and generators..." Great. A solar array capable of producing 36.5 kW of nominal power, located in a canyon forest, will produce 1-2 kW of actual power - useless, except for the dubious purpose of greenwashing propane-powered generation. Is this fraud an...
This sounds like it definitely makes sense in areas where that biomass waste is readily available-- what was being done with that product previously, was it going to a landfill? Being composted/incinerated in some way?
