Multi-terminal HVDC transmission technology using voltage source converters is proposed for integrating large offshore wind farms with transmission grids. Different DC voltage control and power dispatch strategies are proposed to demonstrate the flexibility and capability of such a transmission system in integrating large-scale variable wind generation. Various options for ensuring satisfactory ride...
The paper addresses a novel scheme for the control of variable wind energy and energy storage plant such that the generation and energy storage can deliver a smooth and constant power as demanded by the grid load. In addition, the wind energy generators are assumed large compared to the local grid rating and will contribute to the voltage and frequency regulation of a grid using adaptive frequency...
This paper considers the formal design for the grid frequency control in an offshore wind farm connected with LCC HVDC link. The control paradigm is based on using the grid frequency control to regulate the HVDC rectifier firing angle or DC-link current and hence control the power flow in the system. The dynamic behaviors of the system are verified by comparing the response from derived transfer functions...
