Applications of simplified models to investigate oscillation damping control on the GB transmission system

Energy and environmental issues are amongst the greatest challenges facing the world today and in the future. In response to energy needs and environmental concerns, renewable energy technologies are now considered the future technologies of choice. Renewable energy is produced from freely available and non-polluting natural sources; however, its utilization is not without challenge. There is much interest in Great Britain (GB) among generation developers in the construction of new large-scale onshore and offshore wind farms, especially in Scotland. This paper investigates both SVC and HVDC link oscillation damping control schemes. The simple models presented in this paper represent both the HVDC link and SVC as elements in the power system that exhibit acceptable interaction with other systems elements. This overall system approach is considered in order to test and demonstrate such coordinated control. The simple models, which incorporate a control system, will be useful for implementation in a reduced model of the GB transmission system.
