论文摘要
太阳能电池板等分布式能源资源（DER）具有较小的供应能力，不能直接整合到批发市场中。因此，中介的存在至关重要。中介机构可能是寻求利润的实体（称为聚合者），该实体从生产商那里购买供应，然后在批发电力市场中出售它们。因此，DER集成对批发市场价格，需求和供应有影响。本文的目的是阐明有效汇总对常规发电机市场力量的影响。首先，在有效的汇总下，我们量化了两种情况之间的社会福利差距：当传统发电机是真实的以及何时具有战略性时。当DER不存在时，我们也这样做。其次，我们表明，在没有DER参与的情况下，在DER的存在下由于发电机的市场力量而引起的差距小。最后，我们提供了差距的明确表达，并进行数值实验以获得更深入的见解。本文的主要信息是，可以通过采用有效的DER聚合模型来减轻常规发电机的市场力量。
Distributed energy resources (DERs) such as solar panels have small supply capacities and cannot be directly integrated into wholesale markets. So, the presence of an intermediary is critical. The intermediary could be a profit-seeking entity (called the aggregator) that buys DER supply from prosumers, and then sells them in the wholesale electricity market. Thus, DER integration has an influence on wholesale market prices, demand, and supply. The purpose of this article is to shed light onto the impact of efficient DER aggregation on the market power of conventional generators. Firstly, under efficient DER aggregation, we quantify the social welfare gap between two cases: when conventional generators are truthful, and when they are strategic. We also do the same when DERs are not present. Secondly, we show that the gap due to market power of generators in the presence of DERs is smaller than the one when there is no DER participation. Finally, we provide explicit expressions of the gaps and conduct numerical experiments to gain deeper insights. The main message of this article is that market power of conventional generators can be mitigated by adopting an efficient DER aggregation model.
