This book is the first of its kind to provide a comprehensive framework for connecting wind farms to weak power grids using High Voltage DC technology. Most onshore wind energy potential is located in areas that are hardly inhabited and the majority of wind energy that is being harnessed by European countries is currently offshore, both sourced from locations that lack the presence of a strong power grid. This book focuses on the many challenges the wind farm industry faces integrating both onshore and offshore wind to ‘weak’ grids using HVDC technology. Through case studies and illustrative examples the author presents a framework for theoretical and mathematical analysis of HVDC technology, its application and successful integration of onshore and offshore wind farms. Presents a unified approach for integrating onshore and offshore wind energy to existing AC systems through MTDC grids; Includes an extensive treatment of onshore wind farms connected to LCC HVDC systems; Provides a comprehensive analysis of offshore wind farms connected to VSC HVDC systems.

Power grids are changing significantly with the introduction of large amounts of renewable energy (especially wind) into the system. Integration of wind energy into the grid is challenging as, firstly it increases penetration stresses when compared to conventional generation as the wind is intermittent and fluctuates in power output. Secondly, most of the wind farms are located in offshore or rural areas which have good wind conditions. The grid in these regions is not normally strong. Most of the modern variable speed wind turbines use voltage source converters (VSCs) for grid integration. However, integrating VSCs to weak power grids will cause instability when a large amount of active power is transferred to the grid. In this thesis, the integration of wind farms to very weak power grids is investigated. A multiple input, multiple output (MIMO) model of the grid side VSC of a wind turbine is developed in the frequency domain in which the d-axis of the synchronous reference frame (SRF) is aligned with the grid voltage. Then, this model has been used as the basis for modelling the multiple parallel converters in the frequency domain. In this thesis, to improve the stability of the very weak grid connected of VSCs, a control method based on the d- and q- axis current error is introduced. This controller compensates the output angle of the phase locked loop (PLL) and the voltage amplitude of the converter. Using this controller, full rated active power transfer and fault ride-through are achieved under very weak grid connection. Furthermore, a stabiliser controller based on virtual impedance is proposed in this thesis to achieve stable operation of a very weak grid connected VSC. This stabilising control method enables the VSC to operate at full power and to ride-through faults under very weak grid conditions. Based on this principle, an external device is proposed that can be utilised and connected to a weak point of the grid to allow a large amount of VSC interfaced power generation (e.g. wind power) to be connected to the grid without introducing stability issues.

This thesis presents a comprehensive study on the operation, principles and theory of wind farms consisting of doubly-fed induction (DFIG) and fully-rated converter (FRC) wind generators working together in a hybrid arrangement. The main objective of this study is to develop control strategies for the hybrid arrangement of wind turbines in order to improve the grid code compliance of the overall wind farm by exploiting the unique characteristics of both technologies to support each other in case of a fault happening. As a result, this thesis presents a novel control strategy for fully rated converter wind generators to improve the fault ride through capabilities of DFIG wind turbines during an AC voltage sag. The developed controller enables the creation of an environment where the FRC and DFIG technologies coexist for the purpose of compliance of grid code requirements. This type of environment can be created in both new wind farm developments and in already deployed DFIG-based wind farms where the addition of FRCs results in the overall improvement of the grid code compliance of the wind farm.The novel controller developed in this thesis uses the FRC to supply reactive power to the hybrid wind farm network during faults with the objective of reducing the magnitude of the voltage dip. This has positive effects in DFIG rotor speed and DC voltage variables during and after the fault period. These variables, as explained in the thesis, play a crucial role in stabilising the dynamic fault ride through capabilities of the turbine. Additionally, the novel controller developed in this thesis does not compromise the integrity of the FRC system.This thesis also contributes to the investigation of hybrid wind farms connected to the main grid using voltage source converter high-voltage direct current (VSC-HVDC) as a mean to increase renewable energy penetration and transmission capacity without affecting voltage stability or power quality of the specific case of the Great Britain's (GB) network. One main control approach was investigated on the sending-end converter to integrate offshore wind power from hybrid network where all generated power is injected to the point-to-point DC link with a stiff AC bus at the wind farm network. Additionally, two possible connection topologies of future VSC-HVDC were investigated for steady state and transient conditions. The operation of a multi terminal DC network (MTDC) for hybrid offshore wind farms is analysed with power flow studies of a 5-terminal MTDC model regulated by droop control.Finally, this thesis investigates three VSC-HVDC connections schemes designed to transfer 2.4GW of power from two separate Dogger Bank wind farms to the GB grid, in terms of the investment costs, controllability and reliability against expected scenarios. The benefits and drawbacks of all three scenarios are highlighted. These include the benefits of auxiliary cables on AC and DC site of the multi-terminal connections.
