Linear Recursive State Estimation of Hybrid and Unbalanced AC/DC Micro-Grids Using Synchronized Measurements

Linear Three-phase State Estimation for Lv Grids Using Pseudo Measurements Based on Approximate Power Distributions

The large increase of distributed generation (DG) of photovoltaic (PV) systems in low voltage (LV) grids results in increasing voltage magnitudes and line loadings. Due to a lack of network observability in present LV grids, distribution system operators (DSOs) cannot detect and respond to any limit violations. Even with data collected by the expected rollout of smart meters, full network obser...

Synchronized Phasor Measurements in a Dual Layer Hybrid State Estimator

Original scientific paper The architecture of the proposed Dual Layer Hybrid State Estimator starts with the linear state estimator that only takes synchrophasors as inputs and calculates states of the buses with the deployed Phasor Measurement Units (PMUs) and their adjacent buses. These states are used to obtain the pseudomeasurements that are processed together with conventional SCADA measur...

State Estimation Using Quantized Measurements

In this paper we consider the problem of state estimation for linear dynamic systems using quantized measurements. This problem arises when state estimation needs to be done using information transmitted over a digital communication channel. We investigate how to design the quantizer and the estimator jointly.

Online recursive estimation of remaining life using ultrasonic measurements

This article addresses diagnosis and prognosis of evolving fatigue crack damage in polycrystalline alloy structures. It presents a statistically inspired recursive method for in situ estimation of the remaining useful life in machinery components, based on real-time measurements. The underlying algorithm is built upon (a) symbolic dynamic filtering of (online) ultrasonic sensor data and (b) Kar...
