Original abstract

Hydropower (HP) has played an important role in Europe in recent decades, offering a unique combination of safe, low-cost and clean power generation. Today, it is still one of the largest renewable energy sources (RES), accounting for about 35% of RES electricity generation and its share is estimated to reach 50% by 2025. However, grid stability is threatened by the increasing amount of unregulated energy (wind and solar). Flexibility and dynamics such as energy storage and rapid response are urgently needed to achieve EU policy goals. In such a context, HP can play a key role, not only as a provider of regulated renewable energy, but also due to its ability to balance a renewable energy system in the short term (seconds to minutes) and in the medium/long term (months or even years) through the use of pumped storage technology. All these aspects underline the new role of hydropower, which aims to strengthen grid stability and power supply resilience, and to enable higher penetration of volatile RES. The study provides an overview of the preliminary results obtained by the working groups of the COST Pen@hydropower action. In particular, it presents a first assessment of the flexibility offered by hydropower today at the European level, focusing on different geographical areas, and confirms the key role of hydropower in future scenarios (30% of the flexibility demand at all time scales met by hydropower). An overview of the digitalization solutions and innovative technologies that support the growth of a new generation of sustainable hydropower and the modernization of existing hydropower plants is also provided.

Czech abstract

Vodní energie hraje v posledních desetiletích v Evropě důležitou roli, protože nabízí jedinečnou kombinaci těchto vlastností bezpečné, levné a čisté výroby energie. V současné době je stále jedním z největších obnovitelných zdrojů energie. (OZE), které se na výrobě elektřiny z OZE podílejí přibližně 35 % a odhaduje se, že jejich podíl dosáhne do roku 2020 50 %. 2025. Stabilitu sítě však ohrožuje rostoucí množství neregulované energie (větrné a solární). Pro dosažení cílů EU je naléhavě zapotřebí flexibilita a dynamika, jako je skladování energie a rychlá reakce. politických cílů EU. V tomto kontextu může HP hrát klíčovou roli, a to nejen jako poskytovatel regulované energie z obnovitelných zdrojů, ale také díky své schopnosti vyrovnávat systém obnovitelné energie v krátkodobém horizontu (vteřiny až minuty) a v krátkodobém horizontu (vteřiny až minuty). střednědobém/dlouhodobém horizontu (měsíce nebo dokonce roky) díky využití technologie přečerpávacích elektráren. Všechny tyto aspekty podtrhují novou úlohu vodní energie, jejímž cílem je posílit stabilitu sítě a dodávky energie. odolnost sítě a umožnit vyšší penetraci nestálých OZE. Studie poskytuje přehled předběžných výsledků získaných pracovními skupinami COST. Pen@hydropower. Představuje zejména první hodnocení flexibility, kterou vodní energie nabízí. na evropské úrovni, se zaměřením na různé zeměpisné oblasti, a potvrzuje klíčovou roli vodních elektráren. v budoucích scénářích (30 % poptávky po flexibilitě ve všech časových měřítcích uspokojí vodní energie).
