European Economic impacts of cutting energy imports from Russia: A computable general equilibrium analysis

Marc Vielle, Sigit Pria Perdana

The recent economic sanctions against Russia can jeopardise the sustainability of the European Union's (EU) energy supply. Despite the EU's strong commitment to stringent abatement targets, fossil fuels still play a significant role in the EU energy policy ...

Designing and assessing solar energy neighborhoods from visual impact

Jérôme Henri Kämpf, Amarasinghage Tharindu Dasun Perera, Giuseppe Peronato, Pietro Florio

The optimal diffusion of Building Integrated PhotoVoltaics (BIPV) in cities requires diligent planning to arrange temporal and spatial distribution of energy, while preserving the aesthetics of city landscapes. Benefitting from an increasing quality of 3D ...

Towards a digital workflow to assess visual impact of solar modules and their operation within energy-hubs

Jean-Louis Scartezzini, Silvia Coccolo, Amarasinghage Tharindu Dasun Perera, Pietro Florio

This study proposes an integrated methodology to assess the BIPV potential of existing urban neighborhoods, including social acceptance and grid infrastructure management issues; as a demonstration, a case study in Geneva, Switzerland is considered. In par ...

Aspects of the energy transition and their effects on power systems

Laurent Vincent Pagnier

Most European countries are committed to an energy transition which consists in the substitution of conventional CO2 emitting energy sources by new renewable energy sources (RES), in particular wind and solar power. As opposed to conventional energy source ...

Scenario modelling and optimisation of renewable energy integration for the energy transition

Victor Codina Gironès

A large number of countries have engaged themselves in an energy transition towards more re- newable energy in their energy systems. Motivations stem mainly from the need to reduce CO2 emissions, and from a desire of their population to phase out technolog ...

Energy integration of CO2 networks and Power to Gas for emerging energy autonomous cities in Europe

François Maréchal, Luc Girardin, Raluca-Ancuta Suciu

The concept of urban CO2 networks has been developed to deploy heat pump based district heating and cooling systems in dense urban areas. The use of the CO2 phase change reduces the cost of the heat distribution while allowing to recover waste heat that is ...

Not if, but when? Simulating the impact of timing the nuclear phase-out in Switzerland

Matthias Finger, Reinier Verhoog, Paul Adrianus Van Baal

Swiss electricity companies are faced with uncertainty with regards to the future operation of nuclear power plants in the country. After Fukushima in 2011, the government decided on a gradual phase-out, but only provided a tentative planning. Hence, no ne ...

Potential contributions of wind power to a stable and highly renewable Swiss power supply

Michael Lehning, Annelen Kahl, Albertus Christiaan Kruyt

Using data from two measurement networks, we analyse the following aspects of wind speeds over Switzerland to assess the possibility of high wind power penetration: spatial correlation, persistent low wind power conditions and the diurnal and seasonal wind ...

Assessing the potential increase of seasonal energy storage to mitigate the impact of climate change in Switzerland: Case study of the Grande Dixence dam

Anton Schleiss, Pedro Filipe De Almeida Manso, Jérôme François Sylvain Dujardin

The total storage capacity of the reservoirs in Switzerland represents only 42% of their annual production of electricity, but secures approximately 100% of hydropower’s contribution to the winter electricity supply. In order to avoid spilling, the storage ...

Intra-day electro-thermal model predictive control for polygeneration systems in microgrids

François Maréchal, Mario Paolone, Ramanunni Parakkal Menon

This paper is framed within the context of intra-day optimal control of polygeneration systems and storage connected to microgrids. In particular, the paper proposes an optimal control strategy that accounts for both electrical and thermal processes taking ...

Coupled energy economic model framework for analyzing Swiss electricity markets in changing policy environments

Sophie Maire

Energy policy needs to rely on the proper understanding of the interactions between policy instruments, consumer preferences, investment behavior, market structure, electricity supply, and the wider policy environment. This asks for appropriate modeling to ...

Impact of Storage on the Efficiency and Prices in Real-Time Electricity Markets

Jean-Yves Le Boudec, Dan-Cristian Tomozei, Nicolas Gabriel Gast

We study the effect of energy-storage systems in dynamic real-time electricity markets. We consider that demand and renewable generation are stochastic, that real-time production is affected by ramping constraints, and that market players seek to selfishly ...

An Agent-Based Approach to Virtual Power Plants of Wind Power Generators and Electric Vehicles

Matteo Vasirani

Wind power is gaining in significance as an important renewable source of clean energy. However, due to their inherent uncertainty, wind generators are often unable to participate in the forward electricity markets like the more predictable and controllabl ...

Toward a Multi-Agent Architecture for Market Oriented Planning in Electricity Supply Industry

Edgard Gnansounou, Jun Dong

The liberalization of the electricity supply industry has shifted the analyses and modelling activities from planning to operation. However, project studies and investment appraisal still require medium and long-term anticipation of the electricity market ...
