An emergency load shedding algorithm
2015 5th International Conference on Electric Utility Deregulation and Restructuring and Power Technologies (DRPT), 2015A new emergency load shedding algorithm is pro posed in this paper based on the state plane representation of generator speed and power angle. When the trajectory of the power system stays in concave regions, the system is stable. When the trajectory crosses though the convex regions, the system is detected as unstable state.

Comprehensive Load-Shedding System
IEEE Transactions on Industry Applications, 2010The availability of reliable electrical power supply for petrochemical industries is extremely important not only to maintain continuous production but also from the point of view of overall plant safety. The costs, caused by production losses, due to a partial or a complete blackout easily run up to millions of dollars per blackout.

Designing the Load Shedding Scheme
2017It is very important to have a clear idea about the power system we are concerning on to understand the necessity of a load shedding scheme. The parameters and their values that we use in the under frequency load shedding scheme influence in stabilizing the power system very much.

Load Shedding for Window Joins over Streams
Journal of Computer Science and Technology, 2007We address several load shedding techniques over sliding window joins. We first construct a dual window architectural model including aux-windows and join-windows, and build statistics on aux-windows. With the statistics, we develop an effective load shedding strategy producing maximum subset join outputs.

Optimal load shedding planning with genetic algorithm
2011 IEEE Industry Applications Society Annual Meeting, 2011This paper proposes a novel planning method using genetic algorithm (GA) to achieve minimization of load shedding. The frequency of a power system declines rapidly when generator outage occurs. The general solution is to install sufficient under-frequency relays to pull frequency back to normal range. In this study, a single machine infinite bus (SMIB)

Synopsis based load shedding in XML streams
Proceedings of the 2009 EDBT/ICDT Workshops, 2009Stream systems are susceptible to variations in data arrival rate. At times, data arrival rate may spike up to cause unacceptable output latencies and unpredictable system behavior. Recently, load shedding systems have been proposed to deal with this situation.

On underfrequency load shedding schemes
Proceedings of the Twenty-Second Annual North American Power Symposium, 2002The author discusses some of the factors which must be considered for testing an underfrequency load shedding scheme. Fault simulation and system separation due to faults or out-of-step conditions must be represented. This is necessary for analysis of generator behavior within the system during the abnormal conditions.

Load Shedding for Window Joins over Streams
2006We present a novel load shedding technique over sliding window joins. We first construct a dual window architectural model including join-windows and aux-windows. With the statistics built on aux-windows, an effective load shedding strategy is developed to produce maximum subset join outputs.

QoS-Driven Load Shedding on Data Streams
2002In this thesis, we are working on the optimized execution of very large number of continuous queries defined on data streams. Our scope includes both classical query optimization issues adapted to the stream data environment as well as analysis and resolution of overload situations by intelligently discarding data based on application-dependent quality
