我们提出了一个分层分布式算法来解决最优潮流（OPF）的问题，旨在调度可控分布式能源（DER）的电压调节以最小的成本。所提出的算法具有前所未有的可扩展性，大型多相配电网络，通过共同探索的树/子树结构的大型径向配电网络和结构的线性化配电潮流（LinDistFlow）模型，以获得一个分层的，分布式的实施的原始-对偶梯度算法，解决OPF。所提出的实现显着降低了计算负载相比，集中协调的实现相同的原始-对偶算法，而不损害最优性。在4,521节点的试验馈线上的数值结果表明，所设计的算法通过减少和分配计算量，使收敛速度比集中协调原对偶算法提高了10倍以上。
We propose a hierarchical distributed algorithm to solve optimal power flow (OPF) problems that aim at dispatching controllable distributed energy resources (DERs) for voltage regulation at minimum cost. The proposed algorithm features unprecedented scalability to large multi-phase distribution networks by jointly exploring the tree/subtrees structure of a large radial distribution network and the structure of the linearized distribution power flow (LinDistFlow) model to derive a hierarchical, distributed implementation of the primal-dual gradient algorithm that solves OPF. The proposed implementation significantly reduces the computation loads compared to the centrally coordinated implementation of the same primal-dual algorithm without compromising optimality. Numerical results on a 4,521-node test feeder show that the designed algorithm achieves more than 10-fold acceleration in the speed of convergence compared to the centrally coordinated primal-dual algorithm through reducing and distributing computational loads.
