Abstract

Digital era of technology transforms communication and information systems in a revolutionarily way, which makes our applications more integrated, more connected and smarter. However, conventional energy systems do not adequately benefit from opportunities of digital revolution, yet. Interdisciplinary works in the scope of smart grids grow our expectations from electricity grids such as increase of domestic renewable energy utilization, application of active load management in residences. One of challenging tasks for the digital era of energy systems is the transforming traditional static consumer concept to the active user concept, namely prosumers, who exhibit renewable energy generation potential and share own generation by the energy webs. A major problem for the implementation of practical energy webs is the management of energy balance in grid due to the fact that prosumers lead to the high uncertainty and volatility in generation and demand. Authors suggest that hierarchical tree topology as grid architecture can facilitate energy balance management and energy dispatching mechanisms for future energy webs. Because, acyclic structure and scalability of hierarchical tree (HT) topology present advantages of defining family relationships on the node hierarchy of grids. This property can improve accessibility and controllability of the smart grid and facilitates energy dispatches on the grid. This study gives a discussion on advantages of HT topology for smart grid applications and projects for some opportunities on the way of future energy webs.

面向能源网:未来智能电网的分层树状拓扑结构
数字技术时代以革命性的方式改变着通信和信息系统,使我们的应用程序更集成、更连接、更智能。然而,传统能源系统尚未充分受益于数字革命的机遇。智能电网领域的跨学科研究增加了我们对电网的期望,如提高国内可再生能源的利用率,在住宅中应用主动负荷管理。能源系统数字化时代的挑战之一是将传统的静态消费者概念转变为主动用户概念,即产消费者,他们展现出可再生能源发电的潜力,并通过能源网络分享自己的发电量。由于产消者导致了发电和需求的高度不确定性和波动性,电网的能量平衡管理是实现能源网的一个主要问题。作者认为,分层树结构的网格结构可以促进未来能源网的能量平衡管理和能量调度机制。由于层次树拓扑的无循环结构和可扩展性,在网格节点层次上具有定义族关系的优势。这种特性可以提高智能电网的可及性和可控性,便于电网的能源调度。本研究讨论了HT拓扑在智能电网应用中的优势,以及未来能源网发展道路上的一些机遇。
