未来的灵活电网需要一种完全分布式的智能和控制理念，以促进低碳转型和新兴网络技术的采用。未来的电网需要可扩展的网络管理解决方案，以应对不确定性和复杂性的增加。智能系统和网络控制的基础研究将带来下一代智能电网。本文将网络管理函数形式化为分布式约束优化（DCOP）问题，特别是潮流管理问题。DCOP是在出现冲突控制决策的分散控制系统中进行谈判和仲裁的一种方法。此外，该问题将被可视化并分解为因子图，因子图是将全局函数分解为局部函数积的图形表示。此外，将应用一种消息传递算法，即最大和算法，它可以为分散的协调问题提供几乎最佳的结果，并限制计算和通信问题。
A fully distributed intelligence and control philosophy is needed for future flexible grids to facilitate the low carbon transition and the adoption of emerging network technologies. Future grids need scalable network management solutions in order to cope with the increase in uncertainty and complexity. Fundamental research in intelligent systems and network control will deliver the next generation of intelligent electricity network. This paper presents a network management function formalised as a Distributed Constraint Optimization (DCOP) problem, in particular power flow management. DCOP is an approach to negotiation and arbitration within decentralised control systems where conflicting control decisions arise. Furthermore, the problem will be visualized and decomposed as a factor graph which is a graphical presentation of factorization of a global function into a product of local functions. Additionally, a message passing algorithm, the max-sum algorithm, will be applied which can provide almost optimal results for decentralised coordination problems and limits the computation and communication problems.
