风力发电提供灵活的斜坡产品
Wind Power Providing Flexible Ramp Product
摘要：
可再生能源在电力系统中的渗透不断加深，导致对发电调度灵活性的需求不断增加。具体而言，对于短期运行，这里的灵活性表示应预留足够的斜坡容量，以应对负荷和间歇性发电的预期变化，同时也涵盖一定程度的不确定性。为了满足对灵活坡道容量日益增长的需求，坡道产品市场已经在实践中启动，例如加利福尼亚ISO和中部ISO的市场。有时，为了保证足够的斜坡容量，必须实时提交昂贵的快速启动单元。此外，随着可再生能源发电的渗透率提高，传统机组所提供的灵活性可能不够。事实上，风力发电厂在物理上能够提供灵活性，这有时对整个系统也是经济有效的。在本文中，我们的目的是探讨机制和可能性，包括风电生产商作为坡道供应商，以增加供应的灵活性。为了进行分析，两阶段随机实时机组组合模型考虑坡道容量充裕度制定。案例研究表明，如果允许风力发电提供灵活的斜坡产品，系统和风力发电商都可以受益。
英文摘要：
The deepening penetration of renewables in power systems has contributed to the increasing needs for generation scheduling flexibility. Specifically, for short-term operations, flexibility here indicates that sufficient ramp capacities should be reserved to respond to the expected changes in the load and intermittent generation, also covering a certain amount of their uncertainty. To address the growing requirements for flexible ramp capacity, markets for ramp products have been launched in practice such as the ones in California ISO and Midcontinent ISO. Some-times, to guarantee sufficient ramp capacity, expensive fast start units have to be committed in real-time. Moreover, with higher penetration of renewable generation, the flexibility provided by the conventional units might not be enough. Actually, wind power producers are physically capable of offering flexibility, which is sometimes also economically efficient to the entire system. In this paper, we aim to explore the mechanism and possibility of including wind power producers as ramp providers to increase the supply of flexibility. To conduct the anal-yses, a two-stage stochastic real-time unit commitment model considering ramp capacity adequacy is formulated. Case studies indicate that both the system and the wind power producers can benefit if the wind power is allowed to provide flexible ramp products.
