  • Abstract Taiwan Power Company had analyzed Kinmen power system and proposed underfrequency load-shedding schemes in order to enhance reliability. Unfortunately, for the past six years there have been six outages in Kinmen power system, affecting the reliability of electricity supply. The existing power system defense plan obviously needs discussing. This project will start with analyzing Kinmen power system, including the power flow and transient stability analysis, and then propose a new power system defense plan with Kinmen power system’s weaknesses and characteristics taken into consideration. When disturbances take place, like generators tripping, we expect to reduce the scope of blackout to prevent system collapse and enhance reliability of electricity supply in Kinmen power system.
     The traditional load-shedding scheme is usually designed by a process of trial and error, which is prolix and complex. In this project, we will examine the imbalance between power supply and demand in different unit trips, and systematize to predict the frequency response of the power system. This method can reduce the number of iterations and design a power system defense plan that minimizes the scope of power failure in different events. And it will also consider the impact of the Kinmen power system characteristics and that of high penetration of renewable energy on power system defense plan. In addition, we will consider influences caused by high frequency and voltage conditions as well as low frequency in the power system defense plan. Besides, the ROCOF (Rate of Change of Frequency) relay will be adopted in this project to design a better power system defense plan which can quickly finish the process of load-shedding. We hope the new load-shedding scheme can enhance the reliability of Kinmen power system in the future.
