There is a concern over large, fluctuating wind power injected into a power system, which could affect stability, frequency and power quality of the power system. A method of using three-terminal HVDC system to bundle large scale wind farms with conventional power plants is proposed to overcome this problem. The wind power fluctuation is canceled by regulating the power from the conventional power...
The different operation modes of multiterminal HVDC-VSC systems for large offshore wind farms are analyzed. Control schemes for each power converter are proposed. The wind farm VSCs inject the power to the HVDC grid and are controlled as ideal voltage sources that absorb all the incoming power in normal operation, and reduce the injected power whenever a fault occurs and the DC voltage rises. The...
A multi-terminal voltage source converter based high voltage DC transmission systems (MTDC) was used for grid-connection of large offshore wind power generation. The design of a control system was discussed. A four-terminal system was built to test the control idea. Simulation using PSCAD/EMTDC has been carried out under various load and fault conditions.
Voltage source converter multi-terminal HVDC transmission (MTDC) for the connection of large offshore wind farms to the terrestrial grid is investigated. The voltage-current characteristics of converters for MTDC are presented. A control system for a four-terminal HVDC system is designed and simulated under both normal and abnormal operating conditions.
