| Résumé | (disponible en anglais seulement)
Distributed voltage regulation schemes within active distribution networks (ADNs) are receiving plenty of attention because they reduce latency bottlenecks.
However, previous schemes often employ a trusted moderator to govern agent communication, thereby exposing potential trust issues that may affect agent performance. Blockchain technology can avoid the need for intermediaries, since it is a fully
decentralized network that is governed by agents using distributed consensus mechanisms. Thus, this paper proposes a blockchain-based system for voltage regulation in ADNs that provides a competitive marketplace wherein agents can rationally bid for
voltage regulation services. The proposed system utilizes a smart contract that i) enables asynchronous negotiation between agents to mitigate multiple violations simultaneously using the extended contract net protocol (ECNP), and ii) maintains a
credit score that reflects the trustworthiness of an agent in resolving voltage violations. The proposed system also develops a bidding and pricing scheme for voltage regulation services that considers both active and reactive power contributions. A
permissioned blockchain implementation is used to ensure that only known agents are permitted to access the system. The proposed system is implemented on the Hyperledger Fabric platform, where simulations executed on a 69 bus system demonstrate the
system's ability to mitigate multiple voltage violations simultaneously. As demonstrated by the simulation results, the highlight of the main contribution of the paper is the ability of the proposed system to mitigate multiple voltage violations
simultaneously via the ECNP, thereby utilizing less bidding cycles to resolve voltage violations as compared to the original contract net protocol. |
| Sommaire | (Résumé en langage clair et simple, non publié)
Cet article propose un système reposant sur une chaîne de blocs pour la régulation de la tension dans les réseaux de distribution actifs, qui
constitue un marché concurrentiel dans lequel les agents peuvent faire des offres rationnelles pour les services de régulation de la tension. Selon l'article, la principale contribution est la capacité du système proposé à atténuer plusieurs tensions
hors limites simultanément via l'ECNP, utilisant ainsi moins de cycles d'appel d'offres pour résoudre les tensions hors limites par rapport au protocole de réseau contractuel original. |
