A high penetration level of distributed energy resources (DER) is expected in the future smart grid. Typical examples of DER include distributed generation (DG) units such as photovoltaic panels and wind turbines, and distributed storage (DS) units such as batteries, flywheels and plug-in electric vehicles (PEVs) with vehicle-to-grid capabilities. As the integration of DER mainly takes place in power distribution systems and microgrids which are cost-sensitive in nature, establishing centralized operation and control over a large number of DG and DS units becomes infeasible. On the other hand, decentralized operation and control can be applied based on cost-effective wireless networks and computing devices, and fit well to the plug-and-play nature of DER integration. Despite all the advantages, developing decentralized operation and control schemes via wireless communications in smart grid is technically challenging due to the random output of DG units, buffering effect of DS units, and communication delays and packet losses over a wireless communication medium.****In this Discovery research program, stochastic models will be developed to assess the impact of decentralized DER operation on power distribution system, taking into account the random output of DG units and buffering effect of DS units. Based on the stochastic models, the operation of DER will be optimized to maximize the overall utilization. Moreover, low-cost short-range wireless networks will be leveraged to facilitate the information exchange among DER, based on which distributed consensus based decentralized DER control will be established to improve the stability of microgrid. Innovative networking algorithm and heterogeneous network architecture will be designed to improve the efficiency of wireless communications in microgrid. ****The interdisciplinary nature of the research will identify new opportunities for efficient and reliable DER integration in smart grid that are otherwise impossible in isolated approaches. It will generate new knowledge and train highly qualified personnel (HQP) for both information and communication technology (ICT) and electric power industries.**

未来的智能电网预计，分布式能源资源（DER）的渗透率很高。 DER的典型示例包括分布式生成（DG）单元，例如光伏面板和风力涡轮机，以及带有车辆对电网功能的电池，飞轮和插件电动汽车（PEV）等分布式存储（DS）单元。由于DER的整合主要发生在本质上具有成本敏感的电源分配系统和微电网中，因此建立了对大量DG和DS单元的集中操作和控制，这变得不可行。另一方面，可以根据具有成本效益的无线网络和计算设备应用分散的操作和控制，并且非常适合DER Integration的插件性质。尽管有所有优势，但由于DG单位的随机输出，DS单位的缓冲效果以及无线通信介质的沟通延迟和数据包损失，在技术上。在此发现研究计划中，随机评估buffers node note note note note note note note dist，通过启用型号的影响，在无线通信介质上开发了分散的操作和通过无线沟通在技术上在技术上具有挑战性，在技术上是具有挑战性的。 DS单位。基于随机模型，将优化DER的操作以最大化整体利用率。此外，将利用低成本的短距离无线网络来支持DER之间的信息交换，该网络将基于分布式共有的分散DER控制，以提高微电网的稳定性。创新的网络算法和异质网络体系结构将旨在提高微电网中无线通信的效率。 ****研究的跨学科性质将确定在智能电网中有效且可靠的集成的新机会，而这些机会在孤立的方法中是不可能的。它将产生新的知识并培训高素质的人员（HQP），以提供信息和通信技术（ICT）和电力行业。**
