摘要

多个微电网以自组织的方式连接成为自治实体并接入配电网运行，能够显著提高供电可靠性并降低运行成本。提出了一种针对微电网群优化运行的全分布式算法，旨在替代传统集中协调的方式，解决系统对灵活性、可靠性和经济性的要求。该方法基于点对点通信，只需要稀疏通信网络上的相邻节点交换信息，且通信负担很轻。首先介绍了微电网群优化模型，随后结合具有二阶收敛速度的分布式牛顿法和基于一致算法的信息传递，实现了微电网群运行成本的全分布式运行优化。算例结果表明，该方法具有相较一阶分布式算法更快的收敛速度，且受通信拓扑的影响更小，证明了该方法的可靠性和可扩展性。

Abstract

Integrated together in a self-organized manner

a cluster of microgrids can be connected to the active distribution grid as an autonomous entity

which significantly enhances reliability and reduces operation cost. This paper presents a fully distributed method for optimal operation of microgrid clusters without central coordination. Based on peer-to-peer communication

microgrids need only exchange information between neighbors over a sparse communication network and hence the very light communication burden. By combining the Newton-type second-order algorithm and a consensus-based information exchange

the method can achieve minimum operation cost through a few iterations. Simulation results indicate that the method has faster convergence rate than a first-order algorithm. Besides

the influences of communication networks are also discussed in numerical tests to show the method is reliable

scalable and flexible over centralized schemes.
