论文摘要
在本文中，我们介绍了一种在灵活性协调方案（FCS）中进行灵活性聚合的性能量化的方法，重点是保留层次结构FCS的隐私。量化基于两个性能指标：聚合误差和聚合效率。我们介绍了一种提供单元（FPU）的一种复杂类型的灵活性类型的模拟框架，即储能系统（ESS）。 ESS引起的灵活性协调的跨颞约束，导致聚集误差，以防灵活性来自FPU的异质组。我们确定一个导致聚合误差的参数是ESS的功率与能量比。证明使用其功率与能量比的相似性进行FPU进行了分组，以提高协调性能。此外，我们描述了灵活性需求时间工程对聚合错误的影响，得出结论认为，聚合错误的未来评估应考虑多个代表性的需求时间，这是一项非平凡的任务。最后，我们讨论了开发方法对较大系统大小的方案的适用性。
In this paper we introduce a method for performance quantification of flexibility aggregation in flexibility coordination schemes (FCS), with a focus on privacy preserving hierarchical FCS. The quantification is based on two performance metrics: The aggregation error and the aggregation efficiency. We present the simulation framework and the modelling of one complex type of flexibility providing units (FPUs), namely energy storage systems (ESS). ESS cause intertemporal constraints for flexibility coordination that lead to aggregation errors in case flexibility is aggregated from heterogeneous groups of FPUs. We identify one parameter responsible for the aggregation error to be the power-to-energy ratio of the ESS. A grouping of FPUs using similarity in their power-to-energy ratios is shown to improve the coordination performance. Additionally, we describe the influence of flexibility demand timeseries on the aggregation error, concluding that future assessments of aggregation errors should consider multiple representative demand timeseries, which is a non-trivial task. Finally, we discuss the applicability of the developed method to scenarios of larger system size.
