Abstract

It has been prime objective of any power producer and distributor to supply uninterruptible power to the consumer at its premises with best quality, high reliability and most economy. To ensure quality, reliability and economy, the frequency (f) and voltage of the power supply system should remain constant. If for any reason there is increase in load, or generator outage, or tie line trip there will be inequilibrium between generation and load demand. For this purpose Load Shedding Schemes (LSS) are important and powerful tools in present day power systems (PS) to maintain system stability. They are also quite important where there is lack of adequate spinning reserve margin and shortage of tie line capacity to make up for the lost generation. In this paper critical study of underfrequency LSS (UFLSS) is discussed. The parameters studied include: Static and Dynamic UFLSS. Using DIgSIENT PowerFactory an example of IEEE 009 bus system is also presented.
