The adoption of more electric vehicles (EVs) is going to pose some challenges for the grid due to the increase in demand for high-power charging. These issues will get further exacerbated with energy production moving from synchronous machines toward

The increased integration of distributed energy resources (DERs) in the distribution network with intermittent generation profiles will likely make voltage regulation a difficult task. However, DERs bring both challenges and opportunities, as they ca

This work introduces a decentralized management concept for the urban charging hubs (UCHs) where electric vehicles (EVs) can access multiple charger clusters, each controlled by an aggregator. The given day ahead schedules (DASs) and peak power limit

We describe a method for assessing the value of additional data sources used in the prediction of unwanted events (voltage dips, earth faults) in the power system. Using this method, machine learning models for event prediction using (combinations of

The recent development of EVs with high-capacity batteries and high charging power capabilities leads to an increased demand for fast-charging stations (FCS). However, FCS can cause power quality issues such as voltage drops in distribution grids wit

An ADMM algorithm is proposed for selecting structurally constrained measurement combinations as controlled variables (CVs). The CV selection is based on the self-optimizing control principle, where the goal is to choose CVs such that the steady-stat

Self-optimizing control focuses on minimizing the steady-state loss for processes in the presence of disturbances by holding selected controlled variables at constant set-points. The loss can further be reduced by controlling linear measurement combi

A fusion method for hierarchical decentralized state estimation is investigated with unknown cross-correlation. The process is divided into several local estimators for different subsystems that can operate independently from each other. Each of the
