ABSTRACT

The technical evolution of wind energy conversion system is boosting the penetration of wind power as a mainstream electricity source. Its level of grid penetration and impact in the modern power systems is growing and wind energy is already competitive to traditional fossil energy sources regarding the generation costs. The cumulative installed wind power in the European Union increased from 80 GW in 2010 to expected 200 GW by 2020. It is expected that, following the current trend, the cumulative wind capacity would reach 250 GW by 2030, considering low scenario.

High-power wind turbines are considered as a future trend for industrial application. The offshore technology appears as a main driving force due to its higher wind speeds which produce more power per unit of capacity. Despite nowadays offshore wind is still at an earlier stage of development, its competitive position and lifetime extension are expected to improve as its prices fall. The initial investments (capital expenditures - CapEx) and maintenance costs (operating expenditures - OpEx) of an offshore wind farm appear as the main drawbacks of the technology, but it also presents several advantages that can compensate for its higher costs. Firstly, offshore winds are stronger and steadier, this means that the power production can be notably increased (annual energy production - AEP) in a more reliable source of energy. Secondly, offshore wind farms could be placed near densely populated coastal areas, where the land price is highly expensive, and they would help to meet those energy needs. Finally, the visual impact and noise caused by the wind turbines would be mitigated.

The increase of wind energy utilization leads to an increasingly distributed power electronic-based power system. This new scenario brings promising new architectures and also great challenges for operating the power system with high security and stability. Therefore, the new advanced control methods of power electronic converters are crucial important for keeping system safe, high efficient and high immunity to disturbances and variations.

The future WECS are expected to be grid-supportive, instead of simply grid-feeding elements. Consequently, new functionalities will be demanded by emerging grid codes in order to grant the resilience of the electrical power system and the proper grid integration of an increasingly high penetration of inverter-based generation.

The project aims to pave the road for the upcoming challenges for the grid integration of offshore wind farm. The outcome of the project will be the analysis and control strategies for the wind power converter.
