Multi-Service Battery Operation with Cloud Electricity Storage

摘要

We propose a multi-service framework where large-scale batteries are shared between different users and services. New operational metrics such as multiplexing gain and probability of blocking are defined to assess its efficiency. 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 (100k households) in California and a real grid operation data evaluates the economic value of this special multi-service case. Importantly, this empirical evaluation requires estimating the household behavior under the counterfactual of access to battery; for this, we propose a structural approach leveraging the geographical and temporal price discontinuity in the data.
