Experimental Investigation of Repurposed Kaplan Turbines as Variable-Speed Propellers for Maximizing Frequency Containment Reserve
Francesco Gerini, Elena Vagnoni, Martin Seydoux +2
This study explores the practical viability of repurposing aging Kaplan turbines into variable-speed propellers by employing full-size frequency converters. The motivation behind t…
Enhanced Frequency Containment Reserve Provision from Battery Hybridized Hydropower Plants: Theory and Experimental Validation
Francesco Gerini, Elena Vagnoni, Martin Seydoux +2
This paper presents a solution to address wear and tear of Run-of-River (RoR) Hydropower Plants (HPPs) providing enhanced Frequency Containment Reserve (FCR). In this respect, the…
CFD simulation for Hydraulic Short-Circuit feasibility analysis
A. Morabito, C. Wu, S. Sigali +1
Hydraulic Short Circuit (HSC) application allows the simultaneous pumping and generating operations on different units of the same pumped hydro energy storage (PHES) plants for the…
Optimal Grid-Forming Control of Battery Energy Storage Systems Providing Multiple Services: Modelling and Experimental Validation
Francesco Gerini, Yihui Zuo, Rahul Gupta +3
This paper proposes and experimentally validates a joint control and scheduling framework for a grid-forming converter-interfaced BESS providing multiple services to the electrical…
Local Effects of Grid-Forming Converters Providing Frequency Regulation to Bulk Power Grids
Antonio Zecchino, Francesco Gerini, Yihui Zuo +3
The progressive displacing of conventional generation in favour of renewable energy sources requires restoring an adequate capacity of regulating power to ensure reliable operation…
