In this paper, the mathematical model of type-4 wind turbine topology is developed to represent its dynamic behavior. The main objective of a type-4 wind turbine is to deliver active power to the system, but to perform this action; it must absorb reactive power from the power network, causing disturbances and stress in the rest of the power system. Through the dynamic control system used in the back...
A model suitable for small-signal stability analysis and control design of multi-terminal dc networks is presented. A generic test network that combines conventional synchronous and offshore wind generation connected to shore via a dc network is used to illustrate the design of enhanced voltage source converter (VSC) controllers. The impact of VSC control parameters on network stability is discussed...
In recent years there have been plans to develop large scale offshore wind farms in the North Sea. Dealing with variability of power from such wind farms is an important issue and should be addressed properly in the project developments. An HVDC connection between the offshore wind farm and Norway grid enables the offshore wind farms to benefit from the large hydro generation capacity of Norway for...
