Distributed estimation of oscillations in power systems: An extended Kalman filtering approach

CSEE Journal of Power and Energy Systems, 2019
Online estimation of electromechanical oscillation parameters provides essential information to prevent system instability and blackout and helps to identify event categories and locations.

Accounting for model error in Tempered Ensemble Transform Particle Filter and its application to non-additive model error [PDF]

, 2019
In this paper, we trivially extend Tempered (Localized) Ensemble Transform Particle Filter---T(L)ETPF---to account for model error. We examine T(L)ETPF performance for non-additive model error in a low-dimensional and a high-dimensional test problem. The

A Complex-Valued Stationary Kalman Filter for Positive and Negative Sequence Estimation in DER Systems

Mathematics
In medium- and low-voltage three-phase distribution networks, the load imbalance among the phases may compromise the network voltage symmetry. Inverter-interfaced distributed energy resources (DERs) can contribute to compensating for such imbalances by ...

Distributed Robust Kalman Filtering with Unknown and Noisy Parameters in Sensor Networks

Discrete Dynamics in Nature and Society, 2018
This paper investigates the distributed filtering for discrete-time-invariant systems in sensor networks where each sensor’s measuring system may not be observable, and each sensor can just obtain partial system parameters with unknown coefficients which

Dual-Regulating Feedback Optimization Control of Distributed Energy Storage System in Power Smoothing Scenariox Based on KF-MPC

IEEE Access, 2020
Taking the photovoltaic (PV)-hybrid energy storage system (HESS) composed of the distributed PV power generation and the distributed energy storage as the research object, under the scenario of smoothing PV power fluctuation, a dual-regulating feedback ...

Distributed Fusion Kalman Self-turning Filter

Proceedings of the 2nd International Conference On Systems Engineering and Modeling, 2013
This paper puts forward an optimal and distributed fusion Kalman filter based on the Riccati equation, optimal and distributed fusion The Kalman filter has fewer calculated dimensions and less calculated amount than the centralized global optimal Kalman filter. Therefore, it has greater effect in the practice.

Variational Bayesian‐based adaptive distributed fusion target tracking with unknown sensor measurement losses

IET Radar, Sonar & Navigation, 2022
A new variational Bayesian‐based adaptive distributed fusion unscented Kalman filter (ADFUKF‐VB) algorithm is proposed for the problem of state estimation in a distributed fusion target tracking system with unknown sensor measurement losses.

Distributed Monitoring of Robot Swarms with Swarm Signal Temporal Logic

, 2020
In this paper, we develop a distributed monitoring framework for robot swarms so that the agents can monitor whether the executions of robot swarms satisfy Swarm Signal Temporal Logic (SwarmSTL) formulas.

A mollified Ensemble Kalman filter

, 2010
It is well recognized that discontinuous analysis increments of sequential data assimilation systems, such as ensemble Kalman filters, might lead to spurious high frequency adjustment processes in the model dynamics.

Measurement Sensitivity and Estimation Error in Distribution System State Estimation using Augmented Complex Kalman Filter

Journal of Modern Power Systems and Clean Energy, 2020
Distribution state estimation (DSE) is an essential part of an active distribution network with high level of distributed energy resources. The challenges of accurate DSE with limited measurement data is a well-known problem.
