A robust algorithm is developed for jointly controlling the power and rate of flow in a distributed wireless network. The dynamics of the network is modelled as a discrete-time state-delayed system with uncertainties and the proposed algorithm achieves better SIR performance than a conventional power control scheme. keywords: Robust estimation, congestion control, power control, rate control, w...

Today, the electricity power system is the most complicated engineering system has ever been made. The integrated power generating stations with power transmission lines has created a network, called complex power network. The reliability estimation of such complex power networks is a very challenging problem, as one cannot find any immediate solution methods in current literature. In this pape...

This paper presents a new system-wide harmonic state estimation method with the capability to identify harmonic sources with fewer meters than state variables. Note there are only a few simultaneous harmonic sources among the suspicious buses. By extending the concept of observability, the underdetermined system can be observable when considering the sparsity of harmonic sources. We formulate h...

Hierarchical state estimation algorithms are usually employed in large-scale interconnected power systems, where state estimation usually involves very tedious communications and computations. This paper presents 1) a modified coordination technique that is based on Kalman Filtering, derived from hierarchical state estimation; and 2) a time complexity analysis and experimental implementation to...
