在非同步可再生能源（RES）大量渗透的电网中，低水平的系统惯性增加了频率不稳定的风险。在任何时候都需要提供某种类型的辅助服务，例如惯性和频率响应（FR），以便在发生大功率馈入损失时将系统频率保持在安全限度内。在本文中，我们提出了一个频率安全的优化框架，采购的惯性和FR与不同的动态，这使得应用这些服务的边际定价方案。这种定价方案，推导出一个混合的二阶锥计划（MISOCP）的配方，代表频率安全的限制，允许第一次适当的价值多速FR。
Low levels of system inertia in power grids with significant penetration of non-synchronous Renewable Energy Sources (RES) have increased the risk of frequency instability. The provision of a certain type of ancillary services such as inertia and Frequency Response (FR) is needed at all times, to maintain system frequency within secure limits if the loss of a large power infeed were to occur. In this paper we propose a frequency-secured optimisation framework for the procurement of inertia and FR with diverse dynamics, which enables to apply a marginal-pricing scheme for these services. This pricing scheme, deduced from a Mixed-Integer Second-Order Cone Program (MISOCP) formulation that represents frequency-security constraints, allows for the first time to appropriately value multi-speed FR.
