my.uniten.dspace-215562023-05-04T19:49:29Z Implementation Of Under Voltage Load Shedding And Under Frequency Load Shedding To Prevent Power System Collapse Kamali Ganesan UVLS UFLS FYP 2 SEM 2 2019/2020 Load demands have increased tremendously and this can be clarified when the amount of load demands are higher than the supply generated. Eventually, it causes an imbalance state between generation and load demands and this problem causes disturbances in power system stability such as voltage and frequency instability. Untreated disturbances in the power system will lead to a blackout or power system collapse. In the context of maintaining power system security and reliability, load shedding schemes are introduced. These schemes are introduced as the last choice when the governor is unable to trigger spinning reserve and faulty protection equipment [1] [5]. Load shedding schemes consist of two schemes which are under frequency load shedding (UFLS) and under voltage load shedding (UVLS). These schemes which are UFLS and UVLS are applied when there are significant drop below the minimal range detected in frequency and voltage respectively. For this research, both load shedding schemes are initiated to contingencies events such as N-1 and N-2 contingency. Simulation for this study is conducted using the IEEE 30-bus system in PSSE software. Power flow and dynamic analysis are introduced in this paper as well to identify the stability of the system before applying any disturbance in it. Suitable load shedding relay settings are selected and applied to the contingencies. In this paper, UVLS is initiated when there is a voltage violation in certain local buses after implementation of UFLS. At the end of this paper, UFLS and UVLS are compared in terms of voltage and frequency violations respectively to meet the objective of this paper. 2023-05-03T17:15:00Z 2023-05-03T17:15:00Z 2020-02 https://irepository.uniten.edu.my/handle/123456789/21556 en application/pdf |
