1. Local voltage control in a low voltage grid with high photovoltaic penetration
University essay from Lunds universitet/Institutionen för reglerteknikAbstract : This thesis examines how active power control (Volt-Watt control) and reactive power compensation (Volt-VAr control) can help limit voltage increases on the low voltage grid due to high photovoltaic (PV), installations. Due to the large increase in interest to install small scale PV-systems within residential areas the Distribution System Operator E. READ MORE

3. Minimising Battery Degradation And Energy Cost For Different User Scenarios In V2G Applications : An Integrated Optimisation Model for BEVs
University essay from Uppsala universitet/ElektricitetsläraAbstract : The functionality to both charge and discharge energy from and to the power grid to a Battery Electric Vehicle (BEV) is referred to as Vehicle-to-Grid (V2G). This allows the customer to buy energy when the spot price is low and sell energy when the price is high to make a profit, called energy arbitrage. READ MORE

4. Anomaly Detection in the EtherCAT Network of a Power Station : Improving a Graph Convolutional Neural Network Framework
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : In this thesis, an anomaly detection framework is assessed and fine-tuned to detect and explain anomalies in a power station, where EtherCAT, an Industrial Control System, is employed for monitoring. The chosen framework is based on a previously published Graph Neural Network (GNN) model, utilizing attention mechanisms to capture complex relationships between diverse measurements within the EtherCAT system.

5. Parallel Operation of Grid-Forming Power Inverters
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : The use of renewable energy sources has been increasing during the last few years, both to obtain a less impacting energy production, and because of the limited fossil resources. Renewable sources are connected to the grid using inverters, which can be controlled in two main modes, grid-following, and grid-forming. READ MORE
