Abstract: As the world is transitioning towards highly renewable energy systems, advanced tools are needed to analyze the complex energy networks. Energy system design is, however, challenged by real-world objective functions consisting of a blurry mix of technical and socioeconomic agendas, with limitations that cannot always be clearly stated. As a result, economically sub-optimal solutions will likely be preferable. Here, a method capable of determining the continuum containing all economically near-optimal solutions is presented, moving the field of energy system modeling from discrete solutions to a new era where continuous solution ranges are available. The proposed method is applied to study a range of technical and socioeconomic metrics on a model of the European electricity system. The near-optimal region is found to be relatively flat allowing for solutions that are slightly more expensive than the optimum but better in terms of equality, land use, and implementation time.
