基础设施的空间分布在塑造未来能源系统的社会接受水平方面发挥着关键作用。在这里，我评估了在完全可再生的欧洲电力系统中，当基础设施的发展在各个国家和地区之间更均匀地共享时，成本影响和系统构成的变化。我故意偏离资源导致的成本最优，转向在发电方面更公平和自给自足的解决方案。该分析采用开放优化模型 PyPSA-Eur。我表明，纯粹的成本最优解决方案会导致产能分布非常不均匀，但可以在国家层面上实现更统一的扩张计划，而额外费用只需低于 4%。然而，在各种技术成本假设下，没有电力传输的完全自给自足的解决方案似乎成本更高。
The spatial distribution of infrastructure plays a key role in shaping the levels of social acceptance in future energy systems. Here, I evaluate the cost impact and changes in the system composition when development of infrastructure is more evenly shared among countries and regions in a fully renewable European power system. I deliberately deviate from the resource-induced cost optimum towards more equitable and self-sufficient solutions in terms of power generation. The analysis employs the open optimization model PyPSA-Eur. I show that purely cost-optimal solutions lead to very inhomogeneous distributions of capacities, but more uniform expansion plans can be achieved on a national level at little additional expense below 4%. However, completely autarkic solutions, without power transmission, appear much more costly across a variety of technology cost assumptions.
