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.

分布式能源（DER）的高渗透水平，预计在未来的智能电网。DER的典型示例包括分布式发电（DG）单元，例如光伏板和风力涡轮机，以及分布式存储（DS）单元，例如电池、飞轮和具有车辆到电网能力的插电式电动车辆（PEV）。由于DER的集成主要发生在本质上对成本敏感的配电系统和微电网中，因此在大量DG和DS单元上建立集中式操作和控制变得不可行。另一方面，分散的操作和控制可以基于具有成本效益的无线网络和计算设备来应用，并且非常适合DER集成的即插即用性质。尽管有这些优点，但由于DG单元的随机输出、DS单元的缓冲效应以及无线通信介质上的通信延迟和分组丢失，在智能电网中通过无线通信开发分散式操作和控制方案在技术上具有挑战性。
