Dynamic Stability Analysis on a DC Powered Propulsion System: A Power System With Uncontrolled Rectifiers

Royal IHC is known for building large dredging vessels which collect soil from the seabed. The vessel needs to remain in position, called dynamic positioning, which is done by large thrusters. These are mostly electrically powered thus the total amount of required power can range up to 50 MWs. Royal IHC wants to investigate the possibility of a...

Optimal Tuning of Active Power Gradient Control in Multi-Energy HVAC-HVDC Power Systems

Power systems nowadays are experiencing a significant energy transition characterized by the progressive increment of power electronic interfaced units. Voltage source converters are extensively utilized to interconnect renewable energy sources at various transmission levels, facilitate the asynchronous interconnection of system areas through...

Impact of high penetration of solar PV generation on transient- and voltage stability of the Dutch high voltage grid

The last decade has seen an immense growth in solar PV systems (both large-scale solar PV systems and distributed solar PV systems). It is expected that this growth will continue due to environmental concerns. Since conventional generators are defined by their physics and control, and solar PV systems are defined solely by their control...

Validation of Dynamic Power System Models using Synchrophasor Measurements

A dynamic power system model cannot perfectly predict the behaviour of a physical power system. Model validation tries to answer the question whether the model predicts the behaviour of the physical system sufficiently. This study evaluates if and how a dynamic power system model of the Dutch power grid can be validated using PMU measurements....

Integrated Control System for Frequency and Voltage Support via Type-3 Wind Turbines equipped with Energy Storage System

During previous centuries, humanity had relied on fossil fuels to generate the demanded energy. Nowadays, the extensive use of oil, gas and coal for energy production is becoming a major problem which concerns modern society. Global warming and climate change are the biggest challenges the scientific community has faced. The main factor which...

Feasibility Of Demand Side Response From Electrolyzers To Support Power System Stability

The search for new sources of ancillary services and the projected demand for hydrogen as a medium of energy storage has aroused considerable interest in the use of large scale electrolysers for power system ancillary services. As the number of large scale electrolysers is projected to grow, it is important that the dynamics of these plants are...

Modelling Regional Power Grids for Large-Disturbance Stability Studies

Due to the shift in electrical energy generation from thermal synchronous generators towards various renewable sources, power system stability will become a more pressing issue in the near future. In this thesis, we explore possible improvements to the dynamic grid model currently used by TenneT TSO for large-disturbance stability studies,...

Impact of Large Amounts of Photovoltaic Installations in Low-Voltage Networks on Power System Stability During Transmission System Faults: A German Case Study

It is expected that the share of renewable energy sources will increase to meet rising demand. One of the challenges integrating this distributed generation (DG) into the power system is the behaviour of low voltage connected DG in case of a transmission system fault. This research aims to give recommendations for low voltage (LV) grid codes to...
