Analysis of time varying load for minimum loss distribution reconfiguration
… the switching patterns as a function of time. Either seasonal or daily time studies may be performed. Both manual and automatic switches are used to reconfigure the system for seasonal studies, whereas only automatic switches are considered for daily studies. An algorithm for load …

A Method for the Combination of Stochastic Time Varying Load Effects
… under the combined action of a number of time varying load processes is studied. Loads arrive at points in a Poisson process and are modeled by deterministic shapes for static effects and by continuous random processes for dynamic effects.

Electric Distribution Reliability Analysis Considering Time-varying Load, Weather Conditions and Reconfiguration with Distributed Generation
… with iterators, assuming a single failure at a time. A reconfiguration for restoration algorithm is also created to enhance the accuracy of the reliability evaluation, considering multiple concurrent failures. As opposed to most restoration simulation methods used in reliability analysis, which …

An Enhanced Signal Processing Toolbox for Electrical Energy Monitoring
A nonintrusive load monitor (NILM) aims to perform power system analysis with a minimally invasive sensor profile. A wealth of literature exists for load identification and energy disaggregation under ideal, healthy conditions. However, a significant value proposition of nonintrusive load …

Peak load estimation using load research data
Peak load estimation is a critical element in utility decision making. An electric utility must construct, maintain, and operate equipment sufficient to meet the peak, or maximum demand level. Electric utilities have utilized several methods of analyzing energy consumption which have yielded …

Power System Reliability Analysis with Distributed Generators
… calculations have been performed for static load models and inherently make the assumption that system reliability is independent of load. The study presented here evaluates improvement in reliability over a time varying load curve. Reliability indices for load points and the overall system …

Development of advanced modal methods for calculating transient thermal and structural response
… structures subjected to thermal and mechanical loading. A unified method is presented for deriving successively higher-order modal solutions related to previously developed, lower-order methods such as the mode-displacement and mode-acceleration methods. A new method, called the force derivative …

Mitigating the Cost, Performance, and Power Overheads Induced by Load Variations in Multicore Cloud Servers
<p>Load variations whether in space or time pose a significant challenge to system designers. These load variations may induce inefficiencies such as load imbalance and over-provisioning, resulting in performance/power/cost overheads. The goal of my research is to mitigate such variation-induced …
