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...

Modelling and Assessment of Restoration in Electrical Power Systems with High Penetration of Power Electronic Converters

Power outages can damage severely critical infrastructures such as telecommunication networks, financial services, water supplies and hospitals and completely shutting down production at companies. While most power blackouts usually last from some minutes to few hours, some can last days or even weeks. Furthermore, it is likely that these kinds...

Modelling, control and stability analysis of the COBRAcable project integrated in the Dutch transmission system: Evaluation of the performance of the controllers

The COBRAcable project is one of the major interconnectors being constructed in the North Sea, connecting the Netherlands with Denmark. It is a 325 km submarine cable which will have the ability to transfer 700 MW. The importance of the interconnector is manifold: to facilitate the exchange of renewable energy coming from the onshore Danish...

Operational strategies for HVDC transmission in smart grids: the security versus markets dilemma

Over the last decades, the European transmission system has made many profound changes in the network and has focused on three main concepts: i) flexibility, ii) integration, and iii) sustainability to increase the technological innovations, and to improve the market design. The currently used method<br/>by transmission system operators (TSOs)...

Fundamental Study of Small-Signal Stability of Hybrid Power Systems

In the modern world, the load demands on the electrical grids are increasing at a very high rate. Due to increasing power demands and deregulation of the electrical power, the power systems are operated to their maximum capacities.<br/>Many renewable sources are integrated to the conventional grids to meet the increasing load demands. The HVDC...
