What role might Demand Response play in a (possible) future grid featuring high levels of intermittency?
Back on 8th October, I spoke at All Energy in Melbourne on this topic. Given the questions posed after the session, it seemed that it might be of value to some WattClarity readers if...
Ramp rates, for “Unserved Demand” much higher in this future world
A quick look at how ramp rates would vary (for "Unserved Consumption") in the hypothetical "10x" high intermittency grid.
Considerable spillage, in the high intermittency “10x” scenario
Continuing our analysis of these hypothetical future scenarios to understand the shape of "unserved energy" and hence the potential contribution of Demand Response - today I post about energy spilled in a future with...
What would “demand” look like, in a “10x” intermittent scenario
Laying out the framework for the analysis I'm doing for my presentation at All Energy 2015 - about the role Demand Response might play in a future market dominated by intermittent generation
