On the pooling of hydro assets and grid-scale battery energy storage systems

With increasing relevance, grid-integrated renewable generation affects the operational characteristics of existing networks because of the stochastic nature of the sources. As a result, in countries with high renewable energy in-feed, a shift from downstream power delivery to bi-directional load and information flows can be detected. The transition towards a more sustainable electricity supply requires a more flexible and smarter power infrastructure, prepared to cope with the massive growth in renewable generation. This paper explores an innovative solution to mitigate the impacts of increased renewable energy penetration on the grid.
