Special Issue Information

Dear Colleagues,

A conventional centrally controlled grid turns into a smart grid through the development of information and communication technologies. A smart grid includes many devices and subsystems, such as smart meters, smart appliances, distributed sensors, and intelligent energy management systems in an ICT infrastructure. Therefore, to realize a smart grid, interoperability and seamless convergence between the components should be ensured. However, this is a challenging task because the elements use different data semantic models and communication protocols. For this reason, the issues of interoperability and convergence are recognized as major barriers to the implementation of the smart grid. Therefore, it is necessary to recognize the importance of the interoperability and convergence issues in the smart grid and consequently address them. The focus of this Special Issue is on (but is not limited to):

  • Analysis of the interoperability between smart grid components
  • Review of the interoperability in a power grid
  • Designing an interoperability testbed
  • Evaluation of the level of interoperability in a smart grid
  • Common information model for interoperability in a smart grid
  • Business models supported by the interoperability concept
  • Methods for enabling and/or improving interoperability in a smart grid

Advanced smart grid technologies enable energy prosumers to trade surplus energy from their distributed renewable energy sources with other peer prosumers through peer-to-peer (P2P) energy trading. In many previous works, P2P energy trading was facilitated by blockchain technology through blockchain’s distributive nature and capacity to run smart contracts. However, the feature that all the data and transactions on a blockchain are visible to all blockchain nodes may significantly threaten the privacy of the parties participating in P2P energy trading. There are many previous works that have attempted to mitigate this problem. However, all these works focused on the anonymity of participants but did not protect the data and transactions. To address this issue, we propose a P2P energy trading system on a blockchain where all bids are encrypted and peer matching is performed on the encrypted bids by a functional encryption-based smart contract. The system guarantees that the information encoded in the encrypted bids is protected, but the peer matching transactions are performed by the nodes in a publicly verifiable manner through smart contracts. We verify the feasibility of the proposed system by implementing a prototype composed of smart meters, a distribution system operator (DSO) server, and private Ethereum blockchain. Full article

Smart grids with interoperability improve grid reliability by collecting system information and transferring it to an energy management system and associated applications through a seamless end-to-end connection. To achieve interoperability, it is required to exchange the semantic information within the different domains. The international electrotechnical commission has established the Common Information Model (CIM) tool, which is a standard application programming interface for the exchange of semantic information in power systems. CIM provides a robust framework for accurate data sharing, merging, and transformation into reusable information. However, as CIM provides a basic framework for information exchange, various practical issues arise in establishing an energy management system capable of exchanging information using CIM. This paper aims to offer a comprehensive understanding by summarizing and categorizing the research on the practical use of CIM for interoperability in smart grids. Many papers are analyzed and the issues are classified into CIM extension, harmonization, and validation to address the issues that arise when establishing an integrated information exchange system.
