Pipeline energy storage in district heating systems (DHSs) has great potential to improve electricity–heat coordination and promote the accommodation of renewables in power systems. However, under a decentralized operation scheme, the DHS operator may not have the motivation to utilize pipeline energy storage because it will lead to a rise in temperature and thus increase the system's overall heat loss. To address this challenge, this paper proposes a decentralized electricity–heat coordination framework by sharing part of the benefits of renewables accommodation from a power system to a DHS. A bilevel mathematical model is proposed for a policy designer to evaluate the effects of the proposed framework and determine the best sharing ratio between the two systems. An end-to-end DHS model is developed and used in the bilevel programming to consider pipeline energy storage with an explicit relationship between heat generation and demand. Finally, a case study justifies the effectiveness of the decentralized framework and proves that its performance is almost identical to the centralized power and heat dispatch framework.

一种可再生能源分散式电力供热运行的分担成本方法

区域供热系统（DHS）中的管道储能具有改善电热协调并促进电力系统中可再生能源的容纳的巨大潜力。但是，在分散的运营方案下，DHS运营商可能没有动力利用管道储能，因为这将导致温度升高，从而增加系统的整体热损失。为了应对这一挑战，本文提出了一种分散式的电热协调框架，该框架通过共享从电力系统到DHS的可再生能源住宿的部分收益。为策略设计者提出了一个双层数学模型，以评估所提出框架的效果并确定两个系统之间的最佳共享比率。开发了端到端DHS模型，并将其用于双层编程中，以考虑在热量产生和需求之间存在明确关系的管道能量存储。最后，通过案例研究证明了分散式框架的有效性，并证明了其性能与集中式电力和热力分配框架几乎相同。
