XFLEX HYDRO demonstrators grid services assessment and Ancillary Services Matrix elaboration
Résumé
The overarching objective of the Horizon 2020 European Project XFLEX HYDRO [1] is to develop and demonstrate new technological solutions capable of being integrated in different types of Hydro Power Plants (HPP) aiming to improve their efficiency and performances regarding the provision of several Electric Power Systems (EPS) services.
Such developments are expected to actively contribute to the decarbonization of the European EPS, allowing HPP to have increased capabilities for the provision of advanced grid services in face of an evolving EPS characterized by increased shares of time variable renewable energy sources.
This paper presents the methodology and key results which enabled to establish the so-called Ancillary Service Matrix (ASM) presenting the ability to deliver the different ancillary services of each of the 6 demonstrators of the project combined with the applicable technologies studied in this analysis. These technologies include i) the variable speed technology with Doubly Fed Induction Machine (DFIM) or Full Size Frequency Converters (FSFC), ii) the Smart Power Plant Supervisor (SPPS) enabling to extend the operating range of the hydraulic units in turbine mode based on a better knowledge of the hydro unit wear and tear and associated costs over the full unit operating range, iii) the hydraulic short circuit (HSC) operation leading to simultaneous operation of pump and turbines of Pumped Storage Power Plants (PSPP) and iv) the Hydro-Battery-Hybrid (HBH) applied at Run-of-River demonstrator
