Abstract

There is a growing interest over the last decades in the field of autonomous island grids that is driven mainly by climate reasons. The common objective among the members of the European Union (EU) is the increase of Renewable Energy Sources (RES) penetration in the energy mixture, as well as turning the grid into a smart grid. Consequently, more and more state-of-the-art solutions are being proposed for the electricity generation and the optimization of the energy system management, taking advantage of innovations in all energy related sectors. The evaluation of all available solutions requires quantitative assessment, through the adoption of representative Key Performance Indicators (KPIs) for the projects that are related to smart grid development in isolated energy systems, providing the relevant stakeholders with a useful comparison among the proposed solutions. The evaluation approach that is described in this paper emphasizes the role of the various stakeholder groups who face the proposed solutions by different points of view. Apart from the domains of interest that are also observed in previous approaches, the proposed list also contains a set of legal KPIs, since the regulatory framework can either represent a serious barrier or grant a strong incentive for the implementation of state-of-the-art energy technology and grid management solutions in different countries.

Highlights

  • The two characteristics that make it unique as an approach lie on the facts that (a) the stakeholders are placed in a prominent position when it comes to the determination of the criteria of the evaluation and (b) the inclusion of the legal aspect as one of the Key Performance Indicators (KPIs) domains, since, to the best of our knowledge, no legal KPIs can be identified in the existing literature

  • KPIs categorized per domain with the in the framework of the the list may modified according to the specific in the of the the may be modified according to the in the framework of the of thethe listlist may bebe modified tothe thespecific specific in the framework the SMILE

Summary

Introduction

The electrification and energy provision in islands is a quite complex issue, since the need for energy sustainability poses serious environmental and technical feasibility considerations that always need to be taken into account. Several research projects and studies [1,2,3,4,5] attempt to provide a range of solutions trying to meet cases of high diversification in terms of energy requirements and state-of-the-art technologies utilized. One of the major issues faced is the current cost of island electrification, especially of small and non-interconnected islands, which is very high when compared to that of mainland grids. Most parts of the island grid infrastructure are characterized by small individual grids where new technology solutions need to be evaluated before levelling up in interconnected grids.
