in this paper, a combinational optimization algorithm is introduced to obtain the best size and location of static compensator (statcom) in power systems. its main contribution is considering contingency analysis where lines outages may lead to infeasible solutions especially at peak loads and it commonly can be vanished by load-shedding. the objective of the proposed algorithm is firstly to pr...

Under voltage load shedding (UVLS) and under frequency load shedding (UFLS) is plays vital role in the power system operation. As large disturbances are occur frequently in previous days. Generally these two methods are work independently from each other, and are not designed to integrated way to use their combined effect on load shedding. The reactive power hardly consider in load shedding pro...

this paper presents a new centralized adaptive method under frequency load shedding. sometimes, after initial frequency drop following severe disturbances, although the system frequency returns to its permissible value, however, the system might become unstable due to voltage problems. in this regard, the paper proposes a new centralized adaptive load shedding method to enhance the voltage stab...

We consider the problem of resource allocation in mining multiple data streams. Due to the large volume and the high speed of streaming data, mining algorithms must cope with the effects of system overload. How to realize maximum mining benefits under resource constraints becomes a challenging task. In this paper, we propose a load shedding scheme for classifying multiple data streams. We focus...

Among different protection schemes that save power system stability against a variety of disturbances, load shedding is considered as an effective and last-resort tool to avoid voltage instability. This paper proposes a special protection system design to minimize the load curtailments necessary to restore the equilibrium of operating point with relaxation of both steady state and dynamic restr...

We consider the optimal load-shedding problem in electric power systems where a number of transmission lines are to be taken out of service. The nonlinear power flow equations and the binary decision variables lead to a mixed-integer nonlinear program. We show that the load-shedding problem has separable structure that can be exploited by using the alternating direction method of multipliers. W...

The arrival rate of tuples in a data stream can be unpredictable and bursty. Many stream-based applications have Quality of Service (QoS) requirements that need to be satisfied by the underlying stream processing system. In order to avoid violating predefined QoS requirements during temporary overload periods, a load shedding strategy is necessary and critical for a data stream management syste...

Network monitoring applications are prone to continuous overload situations due to the extreme and highly variable data rates of network traffic, traffic anomalies and network attacks. These overload situations can have a severe and unpredictable impact on the accuracy of monitoring applications, right when they are most valuable to network operators. Load shedding via traffic sampling has rece...

Outage of a heavily loaded transmission line or tripping of large generating unit may lead the system toward collapse. Under such circumstances, compared to other measures, load shedding procedure is an efficient method to make the power system voltage stable when many system variables are out of their normal ranges and the system is driven toward collapse. This paper introduces the concept of ...
