Abstract
Advanced in technologies for the decentralization of applications have enabled micro-grid energy systems that do not rely on central control and optimization but are controlled by their owners. This may eventually enable consumers or intermediaries to specify concrete and diverse conditions on the supply that not only concern throughput, price and stability but also elements as provenance (e.g. that energy is produced from renewable sources) or locality among others. Blockchain technologies have emerged as a possible solution for the integration of the stream of events generated by smart meters and networks, providing tamper-proof ledgers for offerings, transactions and traces. However, that requires languages for expressing conditions that might become complex and have to be executed locally. In this paper, we review the state of decentralization in micro-grids and its requirements, and discuss the role of ontologies as support for expressing constraints in those networks.

Smart grids equipped with bi-directional communication flow are expected to provide more sophisticated consumption monitoring and energy trading. However, the issues related to the security and privacy of consumption and trading data present serious challenges. In this paper we address the problem of providing transaction security in decentralized smart grid energy trading without reliance on trusted third parties. We have implemented a proof-of-concept for decentralized energy trading system us...

Through a proof of concept in SWI-Prolog, this paper demonstrates a business transaction model by which the trading partners can derive their own, personal perspective from shared data. The demonstration is an innovative formalisation of the Resource-Event-Agent (REA) ontology as it allows for switching viewpoints in real-time between one trading-partner’s perspective and that of a trading-partner with an opposing view (i.e. customer or supplier), or a trading-partner independent perspective (e....

The modernization of the distribution grid addresses the need to build an intelligent, reliable, resilient and secure grid that enables consumers to actively participate and benefit from greater and more diverse market opportunities and services. Building this intelligent grid requires not only a robust foundational grid but also pervasive monitoring, protection, automation and control capabilities (including at grid edge), which are beyond the functionalities traditionally available in distribu...

In this paper, we investigate the use of decentralized blockchain mechanisms for delivering transparent, secure, reliable, and timely energy flexibility, under the form of adaptation of energy demand profiles of Distributed Energy Prosumers, to all the stakeholders involved in the flexibility markets (Distribution System Operators primarily, retailers, aggregators, etc.). In our approach, a blockchain based distributed ledger stores in a tamper proof manner the energy prosumption information col...

Generation from distributed renewable energy sources is constantly increasing. Due to its volatility, the integration of this non-controllable generation poses severe challenges to the current energy system. Thus, ensuring a reliable balance of energy generation and consumption becomes increasingly demanding. In our approach to tackle these challenges, we suggest that consumers and prosumers can trade self-produced energy in a peer-to-peer fashion on microgrid energy markets. Thus, consumers and...

Metadata repositories and services support the key functions required by the curation of digital resources, including description, management and provenance. They typically use conventional databases owned and managed by different kinds of organizations that are trusted by their users. Blockchains have emerged as a means to deploy decentralized databases secured from tampering and revision, opening the doors for a new way of deploying that kind of digital archival systems. In this paper we revie...

We present an architecture for peer-to-peer energy markets which can guarantee that operational constraints are respected and payments are fairly rendered, without relying on a centralized utility or microgrid aggregator. We demonstrate how to address trust, security, and transparency issues by using blockchains and smart contracts, two emerging technologies which can facilitate decentralized coordination between non-trusting agents. While blockchains are receiving considerable interest as a pla...

Purpose With the increasing spread of ontologies in various domains, units have gradually become an essential part of ontologies and units ontologies have been developed to offer a better expression ability for the practical usage. From the perspectives of architecture, comparison and reuse, the purpose of this paper is to provide a comprehensive survey on four mainstream units ontologies: quantity-unit-dimension-type, quantities, units, dimensions and values, ontology of units of measure and un...

Blockchain technology is regarded as highly disruptive, but there is a lack of formalization and standardization of terminology. Not only because there are several (sometimes propriety) implementation platforms, but also because the academic literature so far is predominantly written from either a purely technical or an economic application perspective. The result of the confusion is an offspring of blockchain solutions, types, roadmaps and interpretations. For blockchain to be accepted as a tec...
