论文摘要
为了使电力部门脱碳，未来英国（GB）的电力系统将在很大程度上以非同步可再生能源为主导。这将导致低水平的惯性，这是可能导致频率恶化的关键参数。因此，对包含频率偏差的辅助服务的需求将大大增加，尤其是考虑到不久的将来，大型核电站可能会增加最大损失的规模。在本文中，使用惯性依赖性随机单位承诺（SUC）模型来说明在低惯性系统中连接惯性和频率响应提供的好处。我们证明，如果在采购频率响应时未明确考虑惯性水平，则在GB中采购辅助服务的成本可能会增加165％。这些结果凸显了需要重新思考辅助服务市场的结构，如今在GB中，该市场提前一个月在交货中举行。
In order to decarbonise the electricity sector, the future Great Britain (GB) power system will be largely dominated by non-synchronous renewables. This will cause low levels of inertia, a key parameter that could lead to frequency deterioration. Therefore, the requirement for ancillary services that contain frequency deviations will increase significantly, particularly given the increase in size of the largest possible loss with the commissioning of large nuclear plants in the near future. In this paper, an inertia-dependent Stochastic Unit Commitment (SUC) model is used to illustrate the benefits of linking inertia and frequency response provision in low-inertia systems. We demonstrate that the cost of procuring ancillary services in GB could increase by 165% if the level of inertia is not explicitly considered when procuring frequency response. These results highlight the need to re-think the structure of ancillary-services markets, which in GB are nowadays held one month ahead of delivery.
