Abstract

UK government has set the ambitious decarbonisation targets, which up to 30GW of wind generation could be connected to the GB transmission system before 2020. The majority of the new wind generation will be in the Scotland, and offshore in the UK as a whole, where the maximum levels of wind resource are available. To fully use the generated power from wind farm, the higher power transfer capacity of transmission system is required. A range of new transmission technologies such as Thyristor Controlled Series Compensation (TCSC) and embedded High Voltage Direct Current (HVDC) link are planned to reinforce the GB system in order to increase the transmission capacity and improve the oscillatory behaviours. This thesis investigates the effectiveness of this two power flow control devices to enhance the transient stability of the GB power system. A coordinated controller to maximise the effect of TCSC and HVDC link is proposed and designed. The power system can operate at optimal operational point after fault due to setting the appropriate dispatched proportion of controller. The best performance is achieved by comparing various study cases. Meanwhile, the principle to dispatch the power flow is studied and presented in the thesis.
