In this article, an effective method to control a power system during emergency conditions is presented. Based on Fuzzy Linear Programming (FLP), a new technique is developed to solve the Load Shedding and Generation Reallocation (LSGR) optimization Problem. The objective function consists of terms of load curtailments and deviations in generation schedules. The constraints are power system var...

In distributed stream processing environments, large numbers of continuous queries are distributed onto multiple servers. When one or more of these servers become overloaded due to bursty data arrival, excessive load needs to be shed in order to preserve low latency for the query results. Because of the load dependencies among the servers, load shedding decisions on these servers must be well-c...

As most data stream sources exhibit bursty data rates, data stream management systems must recurrently cope with load spikes that exceed the average workload to a considerable degree. To guarantee low-latency processing results, load has to be shed from the stream, when data rates overstress system resources. There exist numerous load shedding strategies to delete excess data. However, the cons...

The purpose of the paper is to analyze the transient stability of an industrial cogeneration system in Hsin-Chu Science-Based Industrial Park using ETAP software. The cogeneration system is installed two 161kV/161kV high-impendence transformers with tap-changer to connect with TPC for decreasing the short-circuit fault current and increasing the fault critical clearing time. The transient stabi...

The load shedding problem is vital to a Data Stream Management System (DSMS). This paper presents the design, implementation, and evaluation of a load shedding method under the guide of the feedback control theory, in order to solve practical problems in medical environment. Thus, the using of operator selectivity, which has been proven not stable enough, is avoided. This paper focuses on the r...

In this demo, we show that intelligent load shedding is essential in achieving optimum results in mining data streams under various resource constraints. The Loadstar system introduces load shedding techniques to classifying multiple data streams of large volume and high speed. Loadstar uses a novel metric known as the quality of decision (QoD) to measure the level of uncertainty in classificat...

A real-time two-way direct load control (TWDLC) of central air-conditioning chillers in 10 wide area is proposed to provide demand response. The proposed TWDLC scheme is designed to 11 optimize the load shedding ratio of every customer under control to ensure the target load to be 12 shed is met at every scheduling period. In order to overcome the load reduction uncertainties of 13 TWDLC, an in...

The reactive nature of traditional under-frequency load shedding schemes can lead to delayed response and unnecessary loss load. This work presents a proactive framework for power system frequency stability. Bayesian filters synchrophasors are leveraged produce predictions after disturbances detected. By being able estimate the future state corrective actions be taken before reaches critical co...
