分布式能量管理系统（DEMS）状态估计分布式异步迭代算法

A Distributed Asynchronous State Estimated Algorithm for Distributed Energy Management System (DEMS)

考虑ＤＥＭＳ数据信息通信延迟的不可预测性，在导出ＤＥＭＳ分布式状态估计可观测条件的基础上，构造了ＤＥＭＳ状态估计分布式异步迭代算法，得出了状态估计分布式异步迭代算法的收敛性定理，设计并实现了分布式异步迭代算法在局域网上的模拟计算，最后以ＩＥＥＥ－３０节点系统为例对所构算法的有效性进行了验证。

By taking the unpredictability of DEMS communication time delay into account,DEMS distributed state estimation asynchronous iteration algorithm was firstly proposed. The observability condition for DEMS distributed state estimation and the convergence condition of the asynchronous iteration algorithm were derived. The simulation Of distributed asynchronous iterative computation on a local area network was also carried out,and the test results have shown the effectiveness ofthe algorithm proposed.
