- Description
- This paper presents the design and implementation of a new method of under voltage load shedding in a power system incorporating the use of wind generators to maintain voltage stability following a severe disturbance. This design considers the dynamic modeling of the load as well as the dynamic model of wind turbines. This work demonstrates a method to determine the minimum amount and the most appropriate location of load shedding. The proposed technique in this research involves an iterative algorithm based on trajectory sensitivity analysis to solve the load shedding problem. The load to be shed for each iteration is set at a small amount. Furthermore, the trajectory sensitivity factor (TSF) at all load buses and aggregated wind generator buses are calculated to provide information about the bus that has the prevalent influence in enhancing the system stability. The bus with the highest TSF is then selected as the location of the load shedding. This process is reiterated until the voltages at all buses are stable. Dynamic simulations are performed with the IEEE 14 bus Reliability Test System as a case study.
