    摘要:

    能源互联网是基于智能电网和可再生能源发展而来的多种能源共享系统。作为能源互联网的关键设备,由信息流控制的能量路由器(ER)可以较好地实现分布式可再生能源所发电能的高效优化传输。详细介绍了现有ER的结构、功能和设计要求,并考虑了能源互联网中引入ER后电能传输路径的优化选择问题。随着电力市场的放开,分布式能源参与电力市场化交易,使得能量流在能源互联网中灵活双向流动。传统调度方式难以区分能量流的源和方向,也不能保证能量流按照合同路径传输,因此提出一种基于撮合交易的最小网损路由算法,并应用于未来能源互联网。该算法考虑了电能质量的差异性及电力传输的异步性和实时性,同时将阻塞管理直接考虑进优化算法中。最后,通过仿真验证了所提优化算法的有效性。

    Abstract:

    Energy Internet is a kind of energy sharing system based on smart grids and renewable energy. As a key equipment of Energy Internet, the energy router(ER)controlled by information flows can better realize the efficient and optimal transmission of electricity generated by renewable energy. Therefore, the main structure, functions and design requirements of existing ERs are reviewed. Besides, the optimal selection of transmission routing is considered after the ER is introduced into Energy Internet. With the opening of power markets, the distributed energy is involved in power market transactions, which makes the energy flow flexibly and bi-directionally in Energy Internet. It is hard for conventional power dispatch method to distinguish the source and specific direction of power flows, and it is not guaranteed that the power is transmitted by contract path. Therefore, a minimum loss routing algorithm based on matchmaking tradeoff competition mechanism is put forward and applied to the future Energy Internet. Among those, the power quality difference, the asynchrony and real-time of power transmission are considered. Meanwhile, the congestion management is directly taken into consideration in the optimization algorithm. Finally, the effectiveness of the proposed optimization algorithm is verified by simulations.
