Abstract:
The penetration of the electric vehicle (EV) has increased rapidly in recent years mainly as a consequence of advances in both transportation and electricity sectors and in response to global pressure to reduce carbon emissions and limit fossil fuel consumption. Large-scale EV integration in power systems has modified the nature of the traditional electric load such that it should be controllable. Moreover, uncertain power sources and demand pose challenges in electricity transmission grid, leading to significant impact on power system security and stability. Therefore, it is timely that a com

Abstract:
Transient stability of electric energy grids is defined as the ability of the power system to remain in synchronism during large disturbances. If the grid is not equipped with controllers capable of transiently stabilizing system dynamics, large disturbances could cause protection to trigger disconnecting the equipment and leading further to cascading system-wide blackouts. Today’s practice of tuning controllers generally does not guarantee a transiently stable response because it does not use a model for representing system-wide dynamic interactions.

碩士<br>義守大學<br>電機工程學系碩士班<br>98<br>This thesis presents preventive control strategies to improve the electric power system transient stability. Critical clearing time is employed to identify the transient stability. The preventive control strategies include generation rescheduling, load shedding, network reconfiguration, and their combinations. The preventive control strategies are applied to ten operating scenarios of a power system which has ten machine and thirty-nine buses. Computer simulation results show the effectiveness of the presented method.

Abstract:
碩士<br>國立海洋大學<br>電機工程學系<br>89<br>Stability study is important and indispensable for power system planning and operations. Load characteristics have the same significance as those of generation and transmission systems. The load characteristics can be represented with load models. However, it is not an easy task to construct an appropriate load model due to the variety of model types as well as the acquisition of load model parameters. A fuzzy model is a set of fuzzy IF-THEN rules for describing system behaviors. The method of fuzzy modeling is able to represent the relationships betw
