基于交替方向乘子法的动态经济调度分散式优化
Decentralized Optimization for Dynamic Economic Dispatch Based on Alternating Direction Method of Multipliers
摘要
Abstract
Following the advances in convex optimization, this paper proposed a decentralized method based on the alternating direction method of multipliers (ADMM) for the dynamic economic dispatch (DED) problem to overcome the difficulties arising from the traditional centralized dispatch method using in smart grid. Inspired by the modeling idea of CIM in IEC 61970 standard, which decomposes the power grid into devices, terminal and connectivity node, a decentralized model of power grid was obtained. Each device exchanges simple messages with its neighbors in the network, and solves the individual sub optimization problem by itself in parallel pattern. No global coordination and synchronizing iterations are needed in the proposed method, which possess the self-healing and plug-in features. Moreover, the convergence of the proposed method is guaranteed since the device objective function and constraints are convex. Numerical simulations on some systems confirm the extremely efficiency and good convergence of the algorithm. It offers a new idea for development of future power grid.关键词
