Study on US-EU integrated power and water systems modelling
Even though water and power systems are highly interdependent, currently those systems are seldom planned and managed together. This prevents us from taking advantage of synergies between the systems and leads to underestimation of risks involved. This study is a model-based analysis of the impact of climate change on water availability and water temperature for the power system and its functioning; for this purpose, a hydrological (HBV) and two power system models (PRIMES-IEM and ENTIGRIS) were developed, adapted, and integrated. The developed soft linkage of models maps future hydro-climatic... projections into future power system operation, and allows to quantify the vulnerability of the power system to changes in the hydrological system due to climate change. Water availability under different climate change scenarios was provided to the energy models to test the resilience of the future power system under changed climatic conditions. The study has analysed three macro-regions in Europe: the Iberian Peninsula, the Danube river basin and the Alpine region with a focus on Switzerland. A further micro-region study of the Adda river basin performed a soft-linkage between the two system models (hydrological and power system) to analyse feedback loops and mimic real time performance. Results show that climate change and renewable energy penetration will have significant and diverse effects on the reliability and vulnerability of the energy system in the different regions also impacting energy prices.
