Providing Stacked Balancing Services using Wind-Storage systems

In order to decarbonize the electricity grid, renewable energy sources must be utilised in con- junction with energy storage to provide ancillary services, which maintain electricity supply quality, reliability and restorability, whilst remaining aordable. Due to a lack of knowledge about the potential of stacking UK ancillary services and...

Development of a Generic Model for Real-time Simulation and Assessment of the Dynamic Performance of a Large Scale Offshore Transmission Network

The Paris Agreement, which calls for countries to channel their efforts to limit global warming would require the deployment of large scale offshore wind energy in the North Sea. This includes the possibility of developing offshore infrastructure for deploying offshore wind power generation with installed capacity ranging from 70 to 150 GW by...

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...

Electrical Grid readiness for the European Energy Transition

Comparative study on the necessary upgrade in European interconnections to sustain solar and wind sources uptake in the energy mix. Grid Development for most difficult borders, and planning recommendations, to reach Paris compatible scenario by 2040.

Technical performance of different DC CB technologies for future HVDC Grids

Multiterminal dc (MTDC) network is preferred due to its reliability, security of supply and flexibility. However, MTDC network also comes with the protection challenges resulting from dc faults. Hence, the dc circuit breaker (DC CB) is imperative in such a network. In these recent years, several DC CB technologies have been proposed and...

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....

A Singular-Value-Decomposition-Based Method For Impact Assessment Of Power Electronic Interfaced Generation On The Harmonic Response In Electrical Power Systems

The connection of offshore wind turbines to the European grid has been growing in the recent years. Many European countries are adopting this renewable energy and are increasing the number of wind power plant additions into their electrical transmission networks. Due to the phase out of conventional power plants (e.g. fossil fuel fired), new...

Real time implementation for Grid-forming control of type-4 wind turbines to mitigate voltage and frequency instabilities in high renewable penetration

The increasing penetration of PE converter interfaced generation units in electrical power systems have given rise to many challenges in the power system operation. Two of the most important challenges are the voltage control and frequency control in the absence of conventional generation units. Furthermore, the PE converters can interact with...

Dynamic System Performance Analysis of a Novel Grid Connection Topology for Offshore Wind Farms Using MMC-HVDC Transmission

Recent projections estimate that the Netherlands needs circa 33 GW of offshore wind capacity in the North Sea to meet the goals of the Paris Agreement. To this end, the Dutch government has very ambitious plans to create new wind sites far from shore and integrate that power generation to the high-voltage power grid in the next years. Due to the...

Exploitation of Power-to-Gas for Ancillary Services Provision (within the Context of Synergy Action TSO 2020)

The progressive phase out of fossil fuel power plants and the integration of variable renewable energy sources, driven by environmental directives striving for the reduction of CO2 emissions, is reshaping how electricity Transmission System Operators (TSOs) plan and operate the power system. The mitigation of uncertainty, which imperils the...

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...

Testing of Fast Transfer Relay by an EMTP-based Approach

Industries such as chemical companies need a continuous power supply and the fast transfer relay Siemens 7uv68 is designed to transfer frompresent feederwhich encounters a fault to an auxiliary feeder and minimizes the transient torque of the induction motors during transfer. The relay will be installed in a DOW power plant in South Tarragona,...

Development of an adaptive intentional controlled islanding scheme and post-islanding corrective control actions

Power systems have undergone major changes the past few decades, leading to an increase in the frequency of occurrence and severity of blackouts. Intentional controlled islanding constitutes the final resort to rescue the system from a blackout by separating the network into islands in a controlled manner. Various post-separation control action...

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,...

Cost benefit analysis of different offshore grid topologies in the North

European countries are showing their willingness to reduce their greenhouse gases emissions in the coming years. For example, the Paris agreement within the United Nations Framework Convention on Climate Change (UNFCCC) is one of the most crucial steps that countries have signed recently. The aim is to cause a lower global temperature increase,...
