Optimal power flow control remains one of the main challenges to be solved before large multi-terminal dc (MTdc) networks can be successfully developed. This article employs a novel strategy to achieve optimal power flow (OPF) control in MTdc networks for large offshore wind power plants (OWPP). The strategy, called Distributed Voltage Control (DVC), is validated on an experimental low-voltage laboratory...
The paper main objective is to provide a feasibility study for the connection of a wind turbine to a dc microgrid. The wind turbine, provided by WES, uses a squirrel-cage generator, which is a given project variable. Hence, the main aspects which determines the performance of the the wind turbine connection to the dc microgrid are related with the turbine control — such as the maximum power point...
Turbine manufactures interest in permanent-magnet synchronous generators (PMSGs) with full-scale converters is rapidly increasing, hence, it becomes important to study the stability and performance of such systems.
Estimates are that circa 40GW of offshore wind power capacity is going to be installed throughout Europe by the end of this decade. In this scenario, a pan-European offshore grid network is needed in order to efficiently integrate large amounts of offshore wind into the different European countries' transmission networks. In this paper, the dynamic model of multi-terminal HVDC (MTDC) transmission...
Doubly fed induction generator (DFIG) still shares a large part in today's wind power market. It provides the benefits of variable speed operation cost-effectively, and can control its active and reactive power independently. Crowbar protection is often adopted to protect the rotor-side voltage source converter (VSC) from transient overcurrent during grid voltage dip. But under unbalanced grid voltage...
