This paper investigates an alternative solution to prevent Load Shedding (LS) triggering during underfrequency and proposes a new technique to restore the frequency during emergency events. Demand response (DR) is considered as one of the most promising Smart Grid concepts that can be used to support the peak demand, whereas, LS is an existing last resort method during emergency grid situations...

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 this paper, we identify issues and present solutions developed – both theoretical and experimental – during the course of developing a data stream management system (DSMS) for applications in a sensor environment. Specifically, we summarize our solutions for CQ processing, trigger mechanisms, and Quality of Service (QoS) management in a stream data processing system. Specifically, we first p...

We consider discrete-time dynamics, for cascading failure in DC power networks, whose map is composition of failure rule with control policy. Under feasible control actions, supply-demand at the nodes is monotonically nonincreasing in magnitude. Under the failure rule, a link is removed permanently if the flow on it exceeds given thermal capacity constraints. We consider a finite horizon optima...

Recently, the number of human Q fever cases in the Netherlands increased dramatically. In response to this increase, dairy goats and dairy sheep were vaccinated against Coxiella burnetii. All pregnant dairy goats and dairy sheep in herds positive for Q fever were culled. We identified the effect of vaccination on bacterial shedding by small ruminants. On the day of culling, samples of uterine f...

MAHAJAN, NIKHIL RAVINDRA. System Protection for Power Electronic Building Block Based DC Distribution Systems. (Under the direction of Mesut E Baran) The purpose of this research has been to develop an agent based protection and reconfiguration scheme for power electronic building block based (PEBB) DC distribution systems. One of the foremost applications would be in the new zonal DC distribut...

This paper proposes a methodology for mitigating the occurrence of cascading failure in stressed power systems. The methodology is essentially based on predicting voltage instability in the power system using a voltage stability index and then devising a corrective action in order to increase the voltage stability margin. The paper starts with a brief description of the cascading failure mechan...
