ABSTRACT
In this chapter, the performance of different controllers in improved unified power quality conditioner devices for a wind energy conversion system (WECS) is discussed. Here, conventional proportional–integral–derivative (PID) and fractional order PID controllers are used to improve the power quality of the system by reducing different power quality issues. For analysis purposes, some practical power quality issues such as voltage dips, swells and harmonics are incorporated into the system at various time instances to analyse the work. In this study, renewable energy sources are examined as a potential solution to the problem of inadequate supply of conventional energy and the necessary increase in load. Among all renewable energy sources, WECS is prioritised because of its advantages. In this chapter, a conventional PID controller is developed, and then a FOPID controller is designed. The models are designed using the MATLAB/SIMULINK software, and the simulations are compared.
