Après avoir écumé les marchés financiers, bon nombre d’observateurs pensent que c’est maintenant au tour du marché de l’énergie. Une quantité impressionnante de chercheurs et de start-ups en tout genre se sont en tout cas lancés sur cette voie. De tous les cas d’usage possible, nous proposons d’analyser l’applicabilité et l’acceptabilité de la blockchain dans le cadre de l’échange d’énergie entre pairs (peer-to-peer energy exchange

In this context, the blockchain approach can be employed to foster this decentralized energy market. In [1], we evaluated several designs that should allow a Distribution System Operator (DSO) to accept peer-to-peer energy exchanges supported by this technology. This acceptance is based on criteria such as a strong link with the wholesale/retail market, the resilience of the consensus to approve a block, the accuracy, traceability, privacy and security of the proposed schemes. We concluded that proof-ofstake (PoS), where the choice of node that creates a block is based on a measure of its wealth, is the only method to fulfill these requirements. In the present paper, we clarify the identification and estimation of bidding models to ensure that the PoS that we are developing is a correct response to two major issues with the PoS methodology, namely the concentration of wealth and the "nothing to stake" issue.

A use case describing interactions among different players that fits the process is also presented. A pseudo-dynamic approach to Global Capacity Announcement as a way to increase penetration of Renewable Energy Sources in a distribution system is elaborated in more details.

Research paper thumbnail of Global capacity announcement of electrical distribution systems: A pragmatic approach

Sustainable Energy, Grids and Networks, Dec 1, 2015

We propose a pragmatic procedure to facilitate the connection process of Distributed Generation (... more We propose a pragmatic procedure to facilitate the connection process of Distributed Generation (DG) with reference to the European regulatory framework where Distribution System Operators (DSOs) are, except in specific cases, not allowed to own their generation. The procedure is termed Global Capacity ANnouncement (GCAN) and is intended to compute the estimates of maximum generation connection amount at appropriate substations in a distribution system, to help generation connection decisions. The pragmatism of the proposed procedure stems from its reliance on the tools that are routinely used in distribution systems planning and operation, and their use such that the possibilities of network sterilization are avoided. The tools involved include: long-term load forecasting, longterm planning of network extension/reinforcement, network reconfiguration, and power flow. Network sterilizing substations are identified through repeated power flow computations. The proposed procedure is supported by results using an artificially created 5-bus test system, the IEEE 33-bus test system, and a part of real-life distribution system of ORES (a Belgian DSO serving a large portion of the Walloon region in Belgium).

Research paper thumbnail of Blockchain: A Novel Approach for the Consensus Algorithm Using Condorcet Voting Procedure

The blockchain technology allows interested parties to access a common register, the update, and ... more The blockchain technology allows interested parties to access a common register, the update, and integrity of which are collectively managed in a decentralized manner by a network of actors. It is the consensus protocol that ensures a common and unambiguous update of transactions by creating blocks of transactions for which integrity, veracity, and consistency are guaranteed through geographically distributed nodes. Bitcoin, the first popular blockchain concept, introduced the Proof of Work consensus based on work validation, and has been extended to thousands of participants. Despite its success and its large use in other crypto-currencies, Proof of Work's disadvantages are a high latency, a low transaction rate, and a high energy expenditure, making it a less-than-perfect choice for many applications. In addition the validation of transactions is not carried out with a definite temporality. For Bitcoin, it takes on average 10 minutes to create a block. However, for certain use cases such as auctions or the exchange of energy, there is a need for this temporality. The purpose of this article is to propose a new type of consensus that is faster, less energy-consuming and that can be synchronized with a time reference. The core of the reflection is the use of the Condorcet voting mechanism to determine the miner.

First, two new stopping criteria are considered. Second, annual losses are evaluated using representative days to approximate the injection duration curve. The extensions are validated on an updated model of a real-life system. The emphasis is on the situation in the Walloon region of Belgium considered in the GREDOR project [1]. A way for a DSO to publish Global Capacity ANnouncement computation results is shortly discussed.

Research paper thumbnail of A case study to assess data management and performance of optimal power flow algorithm based tool in a DSO day-ahead operational planning platform

In order to tackle these bottlenecks, DSOs are investigating several strategies including flexibility activation.This paper looks at the performance evaluation of the Smart Operation tool in the context of flexibility activation with a focus on the day-ahead operational planning. The tool performance is evaluated based on its capability to: 1) effectively align with DSO's existing database 2)accommodate the various real-world needs like handling large network, specific time constraints to ensure proper coordination with the Transmission System Operator (e.g. sending signals before closure of market).
