大多数可再生能源（RES）不提供任何惯性响应。它们在电网中的集成意味着系统惯性的高度降低，这导致频率性能的恶化。因此，为了保持频率安全性，对频率响应的要求显著增加。可替代地，来自辅助源的惯性的增强提供可以缓解该问题。然而，惯性条款的好处还没有得到充分的理解。在本文中，惯性相关的随机机组组合（SUC）工具被应用到量化的惯性的经济价值。结果表明，提高提供的惯性将导致显着的经济节省，虽然这些节省不同的系统条件下。这些结果应该引起市场经营者和投资者的注意，以便为惯性辅助服务市场的设计和惯性辅助服务的投资提供信息。
Most renewable energy sources (RES) do not provide any inertial response. Their integration in a power grid implies a highly reduced level of system inertia, which leads to a deteriorated frequency performance. Then, the requirement for frequency response is significantly increased in order to maintain frequency security. Alternatively, enhanced provision of inertia from auxiliary sources may alleviate this problem. However, the benefits of inertia provision are not yet fully understood. In this paper, an inertia-dependent Stochastic Unit Commitment (SUC) tool is applied to quantify the economic value of inertia. The results demonstrate that enhanced provision of inertia would lead to significant economic savings, although these savings vary under different system conditions. These results should be brought to the attention of both market operators and investors, in order to inform the design of an ancillary-services market for inertia and the investment in auxiliary provision of inertia.
