Viability limits of the renewable source in an electricity mix: The MIXOPTIM analysis methodology

In this article, we use a spectral and statistical analysis of load fluctuations to calculate plausible conditions that an electricity mix of power sources must satisfy to fulfill a variable power demand on a territory. These criteria can be applied to ele ...

Strengthening the Group: Aggregated Frequency Reserve Bidding With ADMM

Maryam Kamgarpour, John Lygeros, Xiaojing Zhang

In a power grid, the electricity supply and demand must be balanced at all times to maintain the system's frequency. In practice, the grid operator achieves this balance by procuring frequency reserves in an ahead-of-time market setting. During runtime, th ...

Unsupervised algorithm for disaggregating low-sampling-rate electricity consumption of households

Christophe Ballif, Lionel Benjamin Bloch, Jordan Holweger, Marina Dorokhova

Non-intrusive load monitoring (NILM) has been extensively researched over the last decade. The objective of NILM is to identify the power consumption of individual appliances and to detect when particular devices are on or off from measuring the power cons ...

Real-time optimization of an experimental solid-oxide fuel-cell system

Dominique Bonvin, Jan Van Herle, Christophe Salzmann, Zacharie Wuillemin, Alejandro Gabriel Marchetti

There still exists a large gap between simulation work and industrial applications in the context of control and optimization of solid-oxide fuel-cell (SOFC) systems. In an effort to bridge this gap, this study describes the experimental implementation of ...

Impact of Synchrophasor Estimation Algorithms in ROCOF-based Under-Frequency Load-Shedding

Mario Paolone, Asja Derviskadic, Guglielmo Frigo, Yihui Zuo

This paper investigates the impact of synchrophasor estimation algorithms in Under-Frequency Load-Shedding (UFLS) and Load-Restoration (LR) schemes, relying on frequency and Rate-of-Change-of-Frequency (ROCOF) measurements produced by Phasor Measurement Un ...

Local Energy Storage and Stochastic Modeling for Ultrafast Charging Stations

Hubert Girault, Heron Vrubel, Yorick Ligen

Multi-stall fast charging stations are often thought to require megawatt-range grid connections. The power consumption profile of such stations results in high cost penalties due to monthly power peaks and expensive linkage fees. A local energy storage sys ...

PMU-Based ROCOF Measurements: Uncertainty Limits and Metrological Significance in Power System Applications

Mario Paolone, Asja Derviskadic, Guglielmo Frigo, Yihui Zuo

In modern power systems, the Rate-of-Change-of-Frequency (ROCOF) may be largely employed in Wide Area Monitoring, Protection and Control (WAMPAC) applications. However, a standard approach towards ROCOF measurements is still missing. In this paper, we inve ...

Dispatch and Primary Frequency Control with Electrochemical Storage: a System-wise Verification

Mario Paolone, Fabrizio Sossan, Mokhtar Bozorg, Yihui Zuo

Uncertainty levels in forecasting of renewable generation and demand are known to affect the amount of reserve required to operate the power grid with a given level of reliability. In this paper, we quantify the effects on the system reserve and reliabilit ...
