Which Flexibility Options Facilitate the Integration of Intermittent Renewable Energy Sources in Electricity Systems?

Purpose of Review
In the last decade, the growing penetration of renewable energy sources has induced an increasing research interest in the analysis of flexible energy systems. In particular, the integration of intermittent renewable energy sources, as wind and photovoltaic energy, requires flexibility to compensate the imbalances between energy demand and supply. The objective of the paper is to provide a comprehensive literature review about the role of flexibility options in different electricity systems with focus on Europe and selected countries.
According to the present analysis, it can be pointed out that the portfolio of flexibility options and the interdependencies between them are based on the prevalent energy system in a country or region.
The research on flexibility measures is mainly driven by the observed energy system characteristics as well as the pursued climate protection strategy. Additionally, it is not possible to cover the prospective flexibility needs with one flexibility option. Moreover, the optimal portfolio of flexibility measures depends on the type of flexibility provision required, the cost-effectiveness and whether the considered energy system is on a national or transnational level.

This article aims at explicitly identifying and quantifying the system integration costs of low-carbon generation technologies in the context of the future, largely decarbonised UK electricity system. As the electricity system of UK is only weakly connected to other countries, it has to provide its balancing needs by a large share by its own, so that this country is of special interest for quantifying system integration costs.Google Scholar
