在美国，由独立系统运营商（iso）监督的多个电力市场计划或正在实施爬坡产品。它们旨在为安全约束下的经济调度提供灵活性，因为由于更高的风力渗透，净负荷（负荷减去不可调度的可再生能源）的不确定性更高。当传统的发电机对不可预见的风坡道做出反应时，传输拥塞就会出现。在这种情况下，储备可能无法作为电力通过网络交付。本文提出了原Midcontinent独立系统运营商（MISO）爬坡能力公式的扩展。提出的可交付斜坡能力公式的关键特征是，它根据位置识别净负荷不确定性的大小。给出了具有可交付爬坡能力的经济调度避免拥堵的实例。
Ramping products are planned or in effect in multiple power markets overseen by independent system operators (ISOs) in the United States (US). They are intended to provide flexibility in security-constrained economic dispatch, given higher uncertainty in net load (load minus non-dispatchable renewable power) due to higher wind penetration. When conventional generators respond to unforeseen wind ramps, transmission congestion can arise. In such situations, reserves may not be deliverable as power across the network. This paper presents an extension of the original Midcontinent Independent System Operator (MISO) ramping capability formulation. The key characteristic of this proposed deliverable ramping capability formulation is that it recognizes the magnitude of net load uncertainty by location. An example is given in which the economic dispatch with deliverable ramping capability avoids congestion.
