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

2. Centralised MPC for Long-term Voltage Stability Control of Power System
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : In a power system it is important to keep voltages at specific levels at network buses. Deviations from that can lead to reduced efficiency of transferred power or, in more severe cases, widespread power outages affecting large parts of society. There exists a variety of power system devices that have the ability to regulate the voltage levels. READ MORE

3. Reactive power compensation of the electricity grid with large-scale offshore wind farms in Sweden : Technical capabilities, grid codes and economic incentives
University essay from Uppsala universitet/ElektricitetsläraAbstract : Year 2040 the goal is to have a 100 % renewable Swedish energy system. Svenska kraftnät (Svk) predicts fully decommissioned nuclear power plants and an increased amount of connected wind power plants, especially offshore, year 2045. READ MORE

4. Voltage Stability and Reactive Power - Introduction of Intermittent Renewable Energy Sources in a Power System
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : The electricity demand increases rapidly, and in order to mitigate climate change the power production needs to be renewable and free from green house gas emissions. When solar and wind power are introduced in the system, voltage instability might become a problem. READ MORE

5. Power Electronic Enhanced Distribution Transformer : Seamless Voltage Regulation with Extended Functionalities
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : On-load tap changers and static synchronous compensators (STATCOM) are the main components for voltage regulation and power quality optimization in the power system. STATCOMs are used in both industrial applications and utility to stabilize the grid and reduce downtime. READ MORE
