STANDARDS ASSESSMENT OF BUSINESS USE CASES PROPOSED IN TDX-ASSIST

The Transmission System Operator and Distribution System Operator information exchange has been identified as a key subject to improve the performance of power systems. The standard assessment of the business objects needed to improve this exchange of information is illustrated in the paper. The standard assessment is based on the pertinent business and system Use Cases identified in European project TDX-ASSIST and on EC Core Standards as defined in IEC 63097 Technical Report Smart Grid Roadmap. These standards are considered as standards having an enormous effect on any Smart Grid application and solution. They are seen as a backbone of a future Smart Grid. The used methodology based in three main steps is detailed and some examples of the standard assessment are described.European Union’s Horizon 202

Towards Software-Defined Protection, Automation, and Control in Power Systems: Concepts, State of the Art, and Future Challenges

Nowadays, power systems’ Protection, Automation, and Control (PAC) functionalities are often deployed in different constrained devices (Intelligent Electronic Devices) following a coupled hardware/software design. However, with the increase in distributed energy resources, more customized controllers will be required. These devices have high operational and deployment costs with long development, testing, and complex upgrade cycles. Addressing these challenges requires that a ’revolution’ in power system PAC design takes place. Decoupling from hardware-dependent implementations by virtualizing the functionalities facilitates the transition from a traditional power grid into a software-defined smart grid. This article presents a survey of recent literature on software-defined PAC for power systems, covering the concepts, main academic works, industrial proof of concepts, and the latest standardization efforts in this rising area. Finally, we summarize the expected future technical, industrial, and standardization challenges and open research problems. It was observed that software-defined PAC systems have a promising potential that can be leveraged for future PAC and smart grid developments. Moreover, standardizations in virtual IED software development and deployments, configuration tools, performance benchmarking, and compliance testing using a dynamic, agile approach assuring interoperability are critical enablers. © 2022 by the authors

Developing Enhanced TSO-DSO Information and Data Exchange based on a Novel Use Case Methodology

Copyright: © 2021 Radi, Taylor, Cantenot, Lambert and Suljanovic. The growing penetration of Renewable Energy Sources (RES) in the electrical power sector has increased the amount of Distributed Generation (DG) units connected at the distribution system level. In this context, new balancing challenges have arisen, creating the need for a novel Use Case methodology to enable an active role at the distribution system level such that Transmission System Operators (TSOs) can coordinate with Distribution System Operators (DSOs) with regard to connected resources for balancing purposes. In this paper, the exploitation of the DSO connected resources for balancing purposes in a market environment is proposed and evaluated via a novel Business Use Case (BUC) methodology based on the categorisation of IEC 62913-1. More specifically, in order to address different balancing market situations, two scenarios are considered with regard to the BUC. The first one represents the data exchange between the TSO, the DSO and the Balancing Service Provider (BSP). The second one, represents an alternative scenario where data are exchanged directly between the TSO and the DSO, where the DSO also take on the role of the BSP. The proposed BUC was also developed in order to validate the required data modelling and exchange mechanisms between DSOs and TSOs in order to exploit DSO connected resources for overall system balancing purposes across different time scales.European Union’s Horizon 2020 research and innovation programme, grant agreement No.774500: TDX-ASSIST project

Management of End-to-end Quality of Service

This document is the result of activity AC1.1 and is a key deliverable of the MESCAL project. It comprises three principal components. The first component is the business model, which defines the principal actors in QoS-based service delivery across multiple domains. The second component is the functional architecture, which identifies the key functional blocks required to support inter-domain QoS delivery. The third component is a set of three solution options that provide QoS-based services, each of which is in accordance with the functional architecture
