To keep the stable power system needs the coordination of various units, such as the generation side. For example, the power system frequency may cause rapid decline due to the connection of large loads. In the past, the conventional power plants played prominent roles in providing the residual load to the fast response to support the power system frequency. Nowadays, renewable energy power plants, such as wind power plants and solar photovoltaic power plants, are considered potential response units to participate in the power system. However, different power plants have different attributes, such as the startup time from cold status to the minimum load, from set point one to set point two. Therefore, classifying the power plants into appropriate levels is significant. In this thesis, the literature review regarding the power system's flexibility factors has been studied. The appropriate class of each power plants according to response time has been defined into primary response, secondary response, and tertiary response. Meanwhile, the typical power plants at present, such as thermal power plants, hydropower plants, wind power plants, solar photovoltaic power plants, biogas power plants, and energy storage facilities, have been researched. The average startup time and ramp rate of each power plant have been investigated. Moreover, the simple simulation of wind turbine pitch angle control based on the MATLAB/Simulink has been conducted. Finally, the classification of different power plants has been concluded based on their specific attributes. Furthermore, the solutions of improving the flexibility of conventional power plants are considered as the future work. At the moment, the outlook for the development of renewable energy and energy storage have also been described.}, language = {en} }
