Frequency Regulation with Storage: On Losses and Profits

Daniel Kuhn, François Richard Vuille, Dirk Lauinger

Low-carbon societies will need to store vast amounts of electricity to balance intermittent generation from wind and solar energy, for example, through frequency regulation. Here, we derive an analytical solution to the decision-making problem of storage o ...

Vehicle-to-Grid for Reliable Frequency Regulation

Dirk Lauinger

Future low-carbon societies will need to store vast amounts of electricity to stabilize electricity grids and to power electric vehicles. Vehicle-to-grid allows vehicle owners and grid operators to share the costs of electricity storage by making the batte ...

SCCER JA-RED - Report on the performance of the implemented solutions with guidelines for subsequent implementation - D1.2.4

Luc Girardin, Luise Middelhauve

The foreseen important increase of the penetration of distributed renewable energies technologies into the electricity distribution grid is expected to lead to some major challenges. On the one hand, a large and synchronous production could lead in certain ...

Reliability and Performance of Model Predictive Control for Demand Response with Residential Heat Pumps

Frédéric Louis-Pierre Raphaël Marie Amblard

Distributed energy resources like solar panels and wind turbines are increasingly replacing fossil fuel energy sources. Due to their natural fluctuations they cause imbalance in the power grid when their production does not overlap with demand. Thus, there ...

Benefits of a Diversified Energy Mix for Islanded Systems

Christophe Ballif, Marine Dominique Cauz, Laure-Emmanuelle Perret Aebi, Lionel Benjamin Bloch, Christian Rod

Achieving energy self-sufficiency is a major challenge for remote areas, especially islands. Various technologies have recently been developed to exploit renewable resources in such areas in order to reduce dependency on fossil fuels. This work focuses on ...

Short-term energy use prediction of solar-assisted water heating system: Application case of combined attention-based LSTM and time-series decomposition

Dolaana Khovalyg, Amirreza Heidari

With improved insulation of building envelopes and the use of low-temperature space heating systems, the share of energy use for domestic hot water (DHW) production in buildings has increased significantly, and nearly become the most energy-expensive servi ...
