In a changing power system with increasing penetrations of distributed energy resources, traditional network tariffs might not be able to meet the underlying requirements. Therefore, it is necessary to assess suitable alternatives. We propose a new two-stage process and evaluation framework to support an informed decision process and test them in a Swiss environment. In the first stage, stakeholder interviews determine the relevant design criteria. In the second step, these are translated into a quantitative evaluation framework. The single indicators are weighted by expert weighting, following the analytic hierarchy process, to arrive at the final ranking. The application in a case study shows that the final ranking of the examined tariff structures depends on expert weighting. It is therefore vital to work on a shared understanding of the importance of the different criteria. Moreover, in a scenario with high shares of distributed energy resources, the volumetric tariff shows the lowest performance independent of expert weighting. This result stresses the importance of adapting network tariffs for a future power system with high penetrations of distributed energy sources. Our open-source evaluation tool can help with an informed and transparent decision process.

如何选择合适的网络资费？ - 评估分布式能源资源日益整合下的网络电价

在不断变化的电力系统中，分布式能源的渗透率不断提高，传统的网络电价可能无法满足基本要求。因此，有必要评估合适的替代方案。我们提出了一个新的两阶段流程和评估框架，以支持明智的决策流程并在瑞士环境中对其进行测试。在第一阶段，利益相关者访谈确定相关的设计标准。第二步，将这些转化为定量评估框架。对单项指标进行专家赋权，按照层次分析法，得出最终排名。案例研究的应用表明，所审查的关税结构的最终排名取决于专家的权重。因此，对不同标准的重要性达成共识至关重要。此外，在分布式能源资源份额较高的情况下，体积电价显示出独立于专家权重的最低性能。这一结果强调了针对分布式能源高渗透率的未来电力系统调整网络电价的重要性。我们的开源评估工具可以帮助实现知情且透明的决策过程。
