A Novel Methodology for the Scalability Analysis of ICT Systems for Smart Grids Based on SGAM: The InteGrid Project Approach

Abstract

Information and Communication Technology (ICT) infrastructures are at the heart of emerging Smart Grid scenarios with high penetration of Distributed Energy Resources (DER). The scalability of such ICT infrastructures is a key factor for the large scale deployment of the aforementioned Smart Grid solutions, which could not be ensured by small-scale pilot demonstrations. This paper presents a novel methodology that has been developed in the scope of the H2020 project InteGrid, which enables the scalability analysis of ICT infrastructures for Smart Grids. It is based on the Smart Grid Architecture Model (SGAM) framework, which enables a standardized and replicable approach. This approach consists of two consecutive steps: a qualitative analysis that aims at identifying potential bottlenecks in an ICT infrastructure; and a quantitative analysis of the identified critical links under stress conditions by means of simulations with the aim of evaluating their operational limits. In this work the proposed methodology is applied to a cluster of solutions demonstrated in the InteGrid Slovenian pilot. This pilot consists of a Large Customer Commercial Virtual Power Plant (VPP) that provides flexibility in medium voltage for tertiary reserve and a Traffic Light System (TLS) to validate such flexibility offers. This approach creates an indirect Transmission System Operator (TSO)—Distribution System Operator (DSO) coordination scheme.

Intelligent Street Lighting in a Smart City Concepts—A Direction to Energy Saving in Cities: An Overview and Case Study

“…There is a growing interest in this topic in scientific publications. Recent research focuses on how to optimize the consumption of street lighting [46], which is consistent with the solutions already presented (case studies), technological innovations are also implemented, including [86]. Much attention is also given to aspects of general energy supply and modern solutions [87].…”

Functional Scalability and Replicability Analysis for Smart Grid Functions: The InteGrid Project Approach

“…The use of clustering in the SRA enabled an evaluation of the interdependence (and dependability) between tools and functions and their impact in the overall system performance, in particular, the impact of observability in MV and LV grid operation, which represents a more realistic scenario. Moreover, this methodology also provides a relevant dataset to study other domains of SRA (i.e., ICT, economic, and regulatory), enabling a more detailed analysis of the requirements and main barriers (see [30] for the ICT domain). Regarding the potential replicability of the different tools by other stakeholders, this work provided a simple step-process for the possible success or failure when replicating the tools.…”

“…These HLUCs have their individual requirements and one or more objectives [27]. Hence, the SRA in InteGrid is developed based on 4 focus areas [28][29][30], mapped to the SGAM in Figure 1. The description of these focus areas is as follows:…”

ICT Scalability and Replicability Analysis for Smart Grids: Methodology and Application

“…Additionally, the ICT SRA approach proposed in [8,9] was based on the qualitative evaluation of the different ICT attributes (reliability, computational resources, and manageability) of components and communication links by stakeholders. The main issue with this method is its reliance on stakeholders' assessment; the level of cooperation must be very high and stakeholders must decide the importance and effect of each attribute for the analysis, which can lead to biased input, particularly from ICT providers, when the number of stakeholders is small.…”
