摘要:

分布式可再生能源的发展使得用户逐步转变为产消者,能源社区协调本地能源分配,允许用户交易能源,为能源系统的提效降本提供了新方向。目前能源社区研究或聚焦于探索综合能源为住宅用户供能但未考虑用户间能源交易,或聚焦于用户间的能源交易但未考虑满足多种能源需求。提出一种计及能源社区产消者的综合能源优化方法,将综合能源服务商和用户作为不同利益主体,基于投标响应机制构建能源社区交易模型,以经济性最优为目标探索综合能源系统的最优设计与运行方案。案例表明,用户通过能源交易机制可有效转移负荷、降低用能成本且在交易中获益。同时,能源社区内产消者的能量交易和协调可降低对上层能源系统的依赖,减小本地可再生能源对上层能源系统的冲击。

Abstract:

The rapid development of distributed renewable energy gradually transforms energy users to prosumers. Energy communities coordinate the local energy distribution and help users to trade energy, which provides a new direction for energy systems to improve its efficiency and reduce energy cost. Most existing researches either focus on integrated energy systems (IES) design but without considering energy trading among users, or focus on energy trading but without consideration of meeting the users’ multi-energy demand. Therefore, this study proposes an optimization approach for IES considering energy communities with prosumers. Taking the integrated energy service providers and uses as different stakeholders, an energy community trading model is established based on the bid-response mechanism, and the optimal design and operation schemes of IES are studied with the aim to maximize economic benefits. The case study results indicate that users can efficiently shift the peak demand through energy trading, and reduce the energy cost and gain profits by trading within the energy community. Meanwhile, the prosumers within energy communities can reduce their dependence on the upper-level energy system through energy trading and coordination, subsequently mitigating the impact of local renewable energy generation on the upper-level energy system.
