Adaptive Equivalent Models for Distribution Networks

As the power system grows more complex and active, equivalent models have become a solution for modelling parts of the network that have limited observability or are confidential or too complex to simulate otherwise. In the past decade, this topic has also made its way to distribution networks because of its transition towards an active network,...

Confronting the Threat: Analysis of the Impact of MaDIoT Attacks in Two Power System Models

The increasing penetration of Internet of Things (IoT) devices at the consumer level of power systems also increases the surface of attack for the so-called Manipulation of Demand through IoT (MaDIoT) attacks. This paper provides a comparison of the impact that MaDIoT attacks could have on power systems with different characteristics, such as...

Detection and Identification of Generator Disconnection Using Multi-layer Perceptron Neural Network Considering Low Inertia Scenario

This research paper presents a method that uses measurements of voltages angles, as provided by phasor measurement units (PMU), to accurately detect the sudden disconnection of a generation unit from a power grid. Results in this research paper have demonstrated, in a practical fashion, that a multi-layer perceptron (MLP) neural network (NN) can...

A study on the propagation of harmonics in a Power System

There has been a rapid development in the growth of Wind power generation in the last decade. This has led to wind power becoming a major contributor to the modern electrical grids. For the grids that are still based on conventional sources of energy, integrating wind power causes a serious impact on their performance. While the Windfarm must...

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....

Digital Twin Application for Congestion Management in Distribution Network

High penetration of rooftop PV generation in the distribution network increases the variability of power flows and the frequency of network and hence congestions occurs at various network locations of the network. Congestions have various defects such as it deteriorates network performance, power quality and therefore can lead to a shutdown by...

PowerFactory-Python based assessment of frequency and transient stability in power systems dominated by power electronic interfaced generation

The deployment of variable renewable energy based power plants is increasing all over the world, however, unlike conventional power plants these are mostly connected to the grid via power electronic interfaces. High penetration of power electronic interfaced generation (PEIG) has an important impact on the inertia of the system, which is of...

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,...
