| Résumé | (disponible en anglais seulement)
Residential energy trading systems (RETS) enable homeowners with distributed energy resources (DERs) to participate in virtualized energy markets that have the
potential to reduce the peak demand of residential communities. Blockchains are key enablers of RETS, by virtue of providing a decentralized, self-governed network that mitigates concerns regarding privacy and transparency. However, more real-world
case studies are needed to evaluate the techno-economic viability of blockchain-based RETS to improve their positive uptake. Thus, this article develops a permissioned blockchain-based RETS, which enables homeowners to select bidding strategies that
consider the individual preferences of their DERs, and further evaluates the impact of the bidding strategies on reducing the peak demand of the community. The proposed system is implemented on the permissioned Hyperledger Fabric platform, where a
decentralized ledger is used to store all energy bids, and a smart contract is used to execute a double auction mechanism and dispatch the homeowner DERs. The proposed system is validated by conducting simulations on a 8-home community using
real-world data, and also by deploying the system to a Canadian microgrid, where the smart contract execution time is benchmarked. Simulation results demonstrate the efficacy of the proposed system by achieving a peak demand reduction of up to 48 kW
(62%), which leads to an average savings of $1.02 M for the distribution system operator by avoiding transformer upgrades. Also, the simulation results show that the execution time of the proposed smart contract is 17.12 seconds across 12 nodes,
which is sufficient for RETS. |
| Sommaire | (Résumé en langage clair et simple, non publié)
Cet article présente un système de commerce de l'énergie dans le secteur résidentiel (SCESR) reposant sur une chaîne de blocs avec permissions,
qui permet aux propriétaires de sélectionner des stratégies d'enchères qui tiennent compte des préférences individuelles de leurs DER, et évalue ensuite l'incidence des stratégies d'enchères sur la réduction de la demande de pointe de la
communauté. |
