The Effect Assessment Method of Design Factors on Search for High Risk Events of Power Systems

摘要

Power systems become large and complex, so the occurrence rates of a great deal of energy loss caused by faults become high. In this situation, the development of the efficient search method for high risk events of power systems is strongly required. Risk is defined as the product of energy loss and its occurrence rate, considering that the goal of power systems is the stable supply of power. This paper presents the newly developed method which can assess accurately and efficiently effects of design factors on high risk events caused by loss of transient stability of power systems. Being focused on control systems, it was applied to the model system composed of 3 generators and 9 buses. The results of application have clarified its effectiveness.
