Abstract
The increasing tendency of installing larger wind power plants as replacement for conventional power generation into the power system leads to the responsibility of wind power plants to control the node voltages. The focus of this project is placed on the development of a wind power plant model for control analysis as well as the design and tuning process of one voltage control architecture. An exemplary wind power plant located in United Kingdom and the corresponding grid code requirements are used as a base case. First, various possible voltage control philosophes are investigated and their advantages and disadvantages characterized. Subsequently, small-signal models of a single wind turbine and the whole wind power plant are developed, being appropriate for voltage control assessment. The functionality of the wind turbine model is verified by means of Eigenvalue analysis and validated against numerical EMT simulations. The wind power plant model is validated by means of load flow simulations. The final design and tuning process of the voltage controller results in a guidance, proposed for this particular control architecture. It provides qualitative outcomes regarding the impact of system delays, grid conditions and various operating conditions of the wind power plant, with and without incorporation of STATCOMs.
