Furthermore, we find that when transmission capacity increases, the proposed bilevel model will still reduce the system cost, whereas the myopic strategy may incur a much higher cost due to over-scheduling of VRES in the day-ahead market and the lack of flexible conventional generators in real time.

To reduce the impact of excessive scarcity prices, we present a new market mechanism, which consists of a Penalty payment for lost load, a supply Incentive, and an energy price Uplift (PIU).

A proper insurance design needs to resolve the following two challenges: (i) users' reliability preference is private information; and (ii) the insurance design is tightly coupled with the renewable energy investment decision.

We also show that the proposed contracts can reduce the system social cost by over 30%, compared with no storage investment benchmark.

In our simulation results, the proposed storage virtualization model can reduce the physical energy storage investment of the aggregator by 54. 3% and reduce the users' total costs by 34. 7%, compared to the case where users acquire their own physical storage.
