The reliable operation of a power system depends on maintaining frequency within predetermined limits around the nominal operating frequency 50 Hertz (Hz). Frequency response is defined as the automatic corrective response provided towards balancing demand and supply. The frequency response characteristic of any system varies depending upon various factors such as the time of the day, season of the year and size of the interconnection. Load Rejection Test is very important to be done for new IPP that will start the commercial operation of their plant and before the IPP station commissioned in the grid system. In this thesis, system fiequency-responses related impacts of power plant load rejection tests are analysed. In this project, several dynamic studies were done to investigate the effect on system frequency if the load rejection test is conducted during peak load period, low load period and for various cases of different load demand, generation capacity and spinning reserve. This study will be used as a guideline to Sabah Load Despatch Centre (SLDC) to make a proper decision before executing Kimanis and SPR Power Plant Load Rejection Test to reduce the impact of interruption to the consumer. The results fiom the PSSE simulation were then compared and analyzed. After that, recommendation was made based on the simulation. The simulation and study were performed using Siemens-PTI PSSJE Version 32 software Power System Simulator for Engineering (PSSIE).
