分布式能源（DER）的渗透，包括分布式发电机和灵活的需求，在世界范围内正在增加，并预计在环境政策和降低成本的鼓励下进一步增加。由于其数量庞大且空间分散，DER有效融入电力市场运营是一项复杂而艰巨的任务。此外，它们的规模相对较小，使得它们直接单独参与电力市场，虽然理论上是可能的，但非常不切实际。本文旨在通过DER Aggregator量化DER在电力市场中的聚合参与的好处。DER聚合器的交互与他的客户和批发市场建模为一个双层规划问题：上层描述DER聚合器的决策;较低的水平包括DER的决策模型和市场清算过程。几种情况下进行检查，以得出一般性的结论，在何种条件下，DER聚合是有益的DER所有者和聚合。
The penetration of distributed energy resources (DER), including distributed generators and flexible demand, is increasing worldwide and is expected to increase further encouraged by environmental policies and decreasing costs. Due to their large number and spatial dispersion, DER's effective integration into the operation of electricity markets is a complex and demanding task. Moreover, their relatively small size makes their direct individual participation in the electricity market, although theoretically possible, highly impractical. This paper aims to quantify the benefits of the aggregated participation of DER in the electricity market via a DER Aggregator. The DER Aggregator's interactions with his customers and with the wholesale market are modeled as a bilevel programming problem: the upper level describes the DER Aggregator decision-making; the lower level encompasses the DERs’ decision model and the market clearing process. Several scenarios are examined in order to draw general conclusions regarding the conditions under which DER aggregation is beneficial for DER owners and the aggregator.
