Electrification is a primary strategy to achieve carbon neutrality. The expected surge in future electricity demand by battery electric vehicle (BEV) necessitates the reinforcement and construction of transmission and distribution (T&D) network. This study aims to evaluate the spatial...

We often take electricity for granted, expecting it at the flick of a switch. Yet behind the scenes, 11.3 million Km of electricity lines and cables bring electricity to 266 million customers. Combating climate change and enhancing the EU's energy independence requires a modernised electricity...

The ongoing transition of our energy systems implies a rise of distributed generators, batteries, and new consumers, including electric vehicles and heat pumps. Previous studies have found that distributed flexibility may substantially benefit wholesale electricity markets, but have neglected...

Heterogeneous interconnections, which link regulated electricity markets to liberalised ones, are becoming increasingly important. Several such interconnections are set to be established in the near future especially between European and North African countries (e.g., Tunisia-Italy,...

Das vorliegende Kurzpapier analysiert die mögliche globale Kostenentwicklung strombasierter Energieträger bis 2050 mit einem Fokus auf die Bereitstellungskosten in Deutschland. Hierzu wurden Studien der letzten fünf Jahre zusammengetragen und deren Ergebnisse für eine vergleichende grafische...

Der Übertragungsnetzausbau erfordert eine Verdreifachung der Netzinvestitionen und wird zu steigenden Netzkosten von heute 10 auf rund 30 Mrd. Euro bis 2045 führen. Die Übertragungsnetztbetreiber haben einen Eigenkapital-Engpass und können den Eigenkapitalbedarf von etwa 70 Mrd. Euro bis...

The ongoing transformation towards a sector-coupled energy system based on renewable generation leads to more complex grid-based energy system models. It is a crucial task to reduce the models' complexities in order to keep optimisation problems tractable while at the same time generating...

The concept of smart grid (SG) was made real to give the power grid the functions and features it needs to make a smooth transition towards renewable energy integration and sustainability. This was done by automating and digitizing the grid to give it the right amount of flexibility and...

The Smart Grid Interoperability Laboratory (SGIL) is situated in two sites of the Joint Research Centre of the European Commission, namely Ispra (Italy) and Petten (The Netherlands). The lab belongsto the Energy Security, Distribution and Markets Unit and the activities vary from energy...

This study analyses the present and future of the European electricity and gas infrastructure, exploring production capacity scenarios and their impact on the electricity system (including the role of interconnections, transmission and distribution grids, prosumers, and storage). It also...

Adopting electric vehicles (EVs) and implementing variable electricity tariffs increase peak demand and the risk of congestion in distribution grids. To avert critical grid situations and sidestep expensive grid expansions, Distribution System Operators (DSOs) must have intervention rights,...

Die Umgestaltung der Stromnetze im Zuge der Energiewende erfordert den Ausbau lokaler und regionaler Netze sowie die Digitalisierung von Prozessen, basierend auf Daten, um erneuerbare Energien zu integrieren und den Anschluss von Verbrauchern wie Elektrofahrzeugen und Wärmepumpen zu...

Due to the ongoing expansion of renewable energies and the increasing energy demand of household consumers, e.g., due to the electrification of the mobility and heating sectors, grid bottlenecks and voltage band violations in low-voltage grids in Germany are expected to occur more frequently in...

A smart grid is the superposition of one physical electricity network on an information system. "Digitalization" (the growing application of information and communication technologies across the economy) enables electricity to break away from exclusive and centralized generation, opening it up...

Given the great influence of artificial intelligence (AI) in people's daily lives due to the key role it plays in digital transformation through its automated decision-making capabilities, ENISA aims to raise awareness of cybersecurity and privacy threats related to various scenarios using...

The transition towards smart grid introduces the potential for revolutionary changes in the present energy management systems. It provides the grid with the necessary functionalities to transform into a decentralized energy system, and integrate large-scale variable renewable energy sources with...

The state of the Ghana Power System reflects a story of progress, challenges, and future potential. Ghana has experienced significant milestones and achievements in its power system, including the development of major infrastructure projects such as the Akosombo Dam and initiatives to expand...

The smart grid (SG) research has continued unabated; however, some challenges, such as stability and security, cause us to focus on sustainable SG, which benefits society. Sustainable SG is complicated and covers many topics that should be summarized systematically. This paper uses CiteSpace to...

Recently, the Indian Prime Minister Appeals to switch off the Light by people during the corona outbreak for 9 min. It also provides a significant challenge to the Indian power grid. A small malfunction of the power system may lead to a huge disaster that may worsen the daily activity of the 100...

This paper uses a whole-system approach to examine different strategies related to the future role of the gas grid in a low-carbon heat system. A novel model of integrated gas, electricity and heat systems, HEGIT, is used to investigate four key sets of scenarios for the future of the gas grid...

The number of prosumers -consumers equipped with decentralized production- is expected to increase following the revised Renewable Energy Directive (2018/2001) and the rising energy prices. The economic literature suggests there is room for demand-side storage that can take two forms:...

Renewable energy communities involve various agents who decide to jointly invest in renewable production units and storage. This paper examines how these communities interact with the energy system and can decrease its overall cost. First, we show that a renewable energy community can contribute...
