Distributed State Estimator Advances and Demonstration
Proceedings of the 41st Annual Hawaii International Conference on System Sciences (HICSS 2008), 2008Present state estimator performance is not 100% reliable. Specifically, there is significant probability that the state estimators may not converge to an acceptable solution. On an industry wide basis, the probability of non convergence is about 5%. The reasons for this performance have been investigated and have been reported in earlier papers.

The previous chapter focused on Wide Area Measurement Systems, that are typically used to oscillations within the transmission systems by comparing time synchronized measurements of different locations. By contrast, this and the following two chapters focus on the use of modern monitoring technologies (compare Chap.

Distributed algorithm for SDP state estimation
2013 IEEE PES Innovative Smart Grid Technologies Conference (ISGT), 2013Smart Grid State Estimation (SE) aims at providing robust and accurate system state estimate for subsequent control operations to accommodate the disturbance of highly intermittent components. Conventional SE for AC Power Grid formulates the estimation process as a non-convex optimization problem, which may reach a local optimal and stop. To compensate

Distribution System Distributed Quasi-Dynamic State Estimator
IEEE Transactions on Smart Grid, 2016With increasing deployment of smart meters and other smart grid sensors in distribution systems, the amount of available measurements has been growing. This change enables implementation of comprehensive distribution system state estimators, a basic tool that provides the real-time model and operating conditions of the distribution network.

Distribution state estimation performances with different state vectors
2013 IEEE Grenoble Conference, 2013Electrical distribution systems of the future must be prepared to face envisaged environmental, technical and even economical constraints: increasing the number of connections of DG, changes in the voltage profile along the feeders, modifications of power losses among others.

Distributed UAV State Estimation in UTM context
2019 6th International Conference on Control, Decision and Information Technologies (CoDIT), 2019This paper proposes the application of a hybrid consensus on information (CI) and consensus on measurements (CM) algorithm, named HCMCI, to deal with the Distributed State Estimation (DSE) problem for a set of cooperating UAVs equipped with heterogeneous on board sensors and limited range communication devices.

An assessment of distributed state estimation
International Journal of Systems, Control and Communications, 2013State estimation is an important topic in the study of dynamical systems. The problem of estimation can be structured into three categories: 1 centralised scheme; 2 decentralised scheme; 3 distributed scheme. Distributed estimation is a compromise between completely centralised and decentralised versions of estimation. In this paper, we will provide an

In this chapter, we extend the decentralized state estimation and event inference techniques discussed in Chap. 9 to distributed settings. We again consider an underlying monolithic system that is modeled as a labeled nondeterministic finite automaton and is observed by multiple observation sites with different observation capabilities (i.e., each site

Distribution system state estimation
IEEE Transactions on Power Systems, 1995A three-phase distribution system state estimation algorithm is proposed in this paper. The normal equation method is used to compute the real-time states of distribution systems modeled by their actual a-b-c phases. A current based formulation is introduced and compared with other formulations.
