This paper introduces a new technique for the distributed voltage and frequency control of the local ac-grid in offshore wind farms based on synchronous generators. The proposed control technique allows the connection of the offshore wind farm using a diode based HVdc rectifier. The use of microgrid control techniques allowed the system comprising the wind farm and the diode HVdc rectifier to be operated...
Power system islanding is gaining interest as a way to improve power supply security and power quality. This has been facilitated by continuing advancements in communications and digital control. For maximum flexibility, power system islands must be capable of operating with different generation and power network topologies. Furthermore, the implication of high capacities of renewable resources on...
Distributed generation (DG) is often used to export power to the utility system. Loss of main supply can cause a severe loading mismatch between DG generation and load consumption. Consequently, the voltage and frequency of the islanded system will cross the allowable limit. Due to this fact, it is essential to control the voltage and frequency in the islanding mode of operation. In this paper, control...
