MVMO-Based Identification of Key Input Variables and Design of Decision Trees for Transient Stability Assessment in Power Systems With High Penetration Levels of Wind Power

Unlike synchronous generators, wind turbines cannot directly respond to large disturbances, which may cause transient instability, due to their power electronic-based interface and maximum power control strategy. To effectively monitor the influence of wind turbines, this paper proposes an approach that combines decision trees (DTs), and a...

Risk-based security assessment of transmission line overloading considering spatio-temporal dependence of load and wind power using vine copula

Location of wind power plants and demand centres are not always close by; hence, the transmission of energy puts a burden on existing grid infrastructure. This unwanted burden necessitates transmission lines to operate more and more frequently close to their operating limits. To alleviate such situations, this research addresses the advantages...

Analysis and planning of power grids: A network perspective

Electric power has become an essential part of daily life: we plug our electronic devices in, switch our lights on, and expect to have power. As the availability of power is usually taken for granted in modern societies, we mostly feel annoyed at its absence and perceive the importance of power during outages which have severe effects on the...

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...

Low Short Circuit Ratio Connection of Wind Power Plants

Primary factor for the site selection during the planning process of the large modern wind farms is the wind climate, which is usually favorable at remote and offshore locations where the public grid is not particularly strong. Among the consequences of this solution is the necessity to connect wind farms to weak points of the grid and the...

Economic and environmental impact assessment of policies promoting wind power participation in energy spot markets.

This master thesis aims at improving the understanding of the factors affecting the cost and emission impacts of wind operations using an engineering- economic (unit commitment) model and generator performance data based on actual US and other country experience, and to analyze the impact of incentive mechanisms on wind power participation in...

Wind power integration: From individual wind turbine to wind park as a power plant

As power capacities of single wind turbine, single wind park and total wind power installation are continuously increasing, the wind power begins to challenge the safety operation of the power system. This thesis focuses on the grid integration aspects such as the dynamic behaviours of wind power during disturbances, and dynamic behaviours of...

Power system operation with large-scale wind power in liberalised environments

Our society revolves around electricity. Most electricity is produced from fossil fuels, such as coal and natural gas. The disadvantages are that their supply is finite and unevenly distributed across the earth. Conventional power stations also emit greenhouse gases. Therefore, sustainable alternativees must be developed, such as wind power. The...

Using copulas for modeling stochastic dependence in power system uncertainty analysis

The increasing penetration of renewable generation in power systems necessitates the modeling of this stochastic system infeed in operation and planning studies. The system analysis leads to multivariate uncertainty analysis problems, involving non-Normal correlated random variables. In this context, the modeling of stochastic dependence is...

Connection of large-scale wind power generation to the Dutch electrical power system and its impact on dynamic behaviour

Installed wind power world wide is increasing rapidly. The increase in wind power in the European electricity grid is expected to have its impact on the system behaviour. A European study, European Wind Integration Study (EWIS), was thus set up to study the impact of wind power. This thesis was carried out in parallel with EWIS and overlaps at...

Integration of stochastic generation in power systems

Stochastic Generation is the electrical power production by the use of an uncontrollable prime energy mover, corresponding mainly to renewable energy sources. For the large-scale integration of stochastic generation in power systems, methods are necessary for the modeling of power generation uncertainty. In this thesis, new tools for the...

Impacts of wind power on thermal generation unit commitment and dispatch

Past, present and future of kites and energy generation

Turby - sustainable urban wind power from the roof top

If current trends are anything to go by, in future we will no longer produce all our electricity in large, central power stations. Small-scale local electricity generation will gain in importance. Sander Mertens, a post-doctoral student at TU Delft, developed the aerodynamic design of a wind turbine which is specifically suitable for built-up...
