Peer to Peer Sharing of Distributed Energy Resources
As the penetration of distributed energy resources in the residential sector
increases, the scope for sharing arrangements expands. We model a peer-to-peer
rental market for rooftop solar and energy storage in the residential sector,
with households seeking to minimize their electricity costs. For varying
adoption levels, we characterize the market rental price, quantity, and
participation rate. We find that up to 15% adoption, the peer-to-peer market
generates a surplus comparable to that attainable though a centralized sharing
model. The peer-to-peer market can incentivize an increase in total adoption in
the long run. We find that direct subsidies would be a cheaper way to increase
adoption if enabling the peer-to-peer market increases distribution grid costs
by more than a few percent. This cost increase would be related to how locally
the peer-to-peer market can match renters and owners. We compute metrics of
this localness and find that the market clears quite locally for a wide range
of adoption rates
Cloud Storage for Multi-Service Battery Operation (Extended Version)
Electrical batteries are able to provide a wide range of services to the
electricity system. However, the main barrier to their development is the cost,
which can be overcome by the provision of multiple services. This paper
proposes a multi-service framework where large-scale batteries are shared
between different users and use cases by defining operational metrics such as
multiplexing gain and probability of blocking. We apply this framework to the
specific case of sharing a battery between two services: grid congestion
management and Cloud Storage for households. The proposed Cloud Storage service
allows end users to have access to virtual storage capacities, while taking
advantage of the flexibility of cloud services. An empirical analysis of this
model based on a large set of household consumption data in California and a
real grid use case from the French Transmission System Operator (RTE) evaluates
the economic value of multi-service batteries providing Cloud Storage and grid
congestion management
