Nexus-e: A platform of interfaced high-resolution models for energy-economic assessments of future electricity systems

Energy systems are transitioning toward sustainable power generation largely due to new policies that motivated by climate and renewable targets. This transition is felt throughout the entire economy affecting long short term operations of energy system. In last decade, research community has made significant efforts model its impacts. Typically, these models focus on a limited subset different components energy-economic system, including investments in centralized distributed generation, electricity markets, electric grids, security supply, macro-economic effects. However, there questions require analysis how aspects connected each other they may interact. Therefore, stressed need leverage across domains enhance capabilities robustness their results. Due partly high complexity combining developed tangential domains, few attempts have been full interactions among interdependent The Nexus-e: interconnected modeling platform aims show this gap can be filled demonstrating an interdisciplinary set integrated framework linking them through structured interfaces. combines four bottom-up capture system one top-down represent much broader scope as compared traditional stand-alone approaches. paper, we study benefits limitations interfaces established modules Nexus-e with reference Swiss European context.
