This is supposed to be a least cost model. Solar reaching up to 4.3 times capacity. I would expect that much of the curtailment would be replaced by “flexible loads” controlled by the grid, most of which would be hydrogen generation. The hydrogen could be stored and used for longer term storage/generation and/or transportation fuel.

2020-09-03 Distributed Generation And Islanding

There is a lot of concern for safety when DGs (distributed generators) are connected to the power grid. The grid operators must ensure that none of the DGs feed back into the grid when the grid generator is not operating. They go through several scenarios in this article. https://electrical-engineering-portal.com/protection-impacts-intentional-islanding-distributed-generation From what I see the DG
