The increasing trend towards large-scale deployment of wind energy imposes numerous operational challenges regarding large integration of wind power to the transmission system including the maintenance of system stability due to the uncertain nature of wind power. Thus, the traditional way of operating and controlling wind turbines and wind power plants are becoming less acceptable. Furthermore, wind power plants are progressively being subjected to the Transmission network operators (TSO's) regulations and are required to operate as a single controllable unit, similar to the conventional power plants, to provide active power regulation. To provide such a functionality, wind turbines in a wind farm must provide more flexible output power control in a quick and safe operating manner. Additionally, the operation of the wind turbines must be coordinated so as to operate the whole wind power plant as a single controllable entity. The main goal of this thesis is to generate a wind farm Simulink model that captures all the essential dynamics for the wind farm controller design and load analysis. To achieve this main aim, a mathematic wind farm model has been developed which offers sufficiently fast simulation for iterative controller design task, and contains a suitable wind-field model that provides a suitable representation of the wind-field and wake propagation through the wind farm. The wind farm controller design with the objectives of primary frequency response and power optimisation has also been investigated.
