This paper describes a discrete event simulation model of the post-earthquake restoration process for electric power systems. The model explicitly represents the real-life restoration process, enabling development of geographically disaggregated, quantitative restoration curves with uncertainty bounds, a dynamic map showing the spatial distribution of outages changing over time, and information on how personnel and repair materials are used throughout the process. The new restoration modelling approach is applied to the Los Angeles Department of Water and Power electric power system. Simulation results for the 1994 Northridge earthquake indicate that the model is capable of accurately estimating the restoration time and spatial sequence of the recovery process. The model aims to help improve the quantitative restoration time estimates that are required to estimate economic losses due to business interruption caused by power outages, and identify and compare the effectiveness of different ways to improve the restoration process in future earthquakes.

A Kalman Filter Based Approach for Light Flicker Evaluation of Power Systems Kose, Neslihan; Salor, Ozgul; Leblebicioğlu, Mehmet Kemal (2009-01-01) In this paper, a Kalman filtering based approach is proposed to measure the light flicker of the electricity transmission systems. Analytical expressions of the instantaneous light flicker sensation are obtained beginning from a voltage waveform and these expressions are used to obtain a flicker estimation method based on the IEC (International Electrotechnical Commission) flickermeter. In the proposed method, the frequency domain components of the waveform are obtained by Kalman filtering and these compone...
Design, fabrication and implementation of a vibration based mems energy scavenger for wireless microsystems Sarı, İbrahim; Balkan, Raif Tuna; Department of Mechanical Engineering (2008) This thesis study presents the design, simulation, micro fabrication, and testing steps of microelectromechanical systems (MEMS) based electromagnetic micro power generators. These generators are capable of generating power using already available environmental vibrations, by implementing the electromagnetic induction technique. There are mainly two objectives of the study: (i) to increase the bandwidth of the traditional micro generators and (ii) to improve their efficiency at low frequency environmental v...
A self-powered integrated interface circuit for low power piezoelectric energy harvesters Chamanian, S.; Zorlu, O.; Külah, Haluk; Muhtaroglu, A. (2013-12-18) This paper presents a CMOS integrated interface circuit for piezoelectric energy harvesters (PEH). A fully self-powered circuit, based on Synchronous Electric Charge extraction (SECE) technique, is implemented for non-resonant piezoelectric harvesters generating low power, in 10s to 100s mu W range. The circuit is realized in standard 180 nm UMC CMOS technology. A switch control circuit is designed and optimized to extract maximum power independently from excitation changes of the PEH. The total power loss ...
Analysis of a Wind Energy Conversion System with Doubly-Fed Induction Generator in healthy and Fault Condition via Simulation Giaourakis, Dimitrios G.; Safacas, Athanasios N.; Tsotoulidis, Savvas (2011-09-10) In this paper, a wind energy conversion system that uses the "Cascade technology" especially the structure of Doubly-Fed Induction Generator (DFIG) is presented and analyzed. Moreover, a simulation of this wind energy conversion system under fault conditions in MATLAB/SIMULINK is done and the results are evaluated. Open-circuit faults in one IGBT or in two IGBTs are studied.
Fast simulation of muons produced at the SHiP experiment using Generative Adversarial Networks Ahdida, C.; et. al. (2019-11-01) This paper presents a fast approach to simulating muons produced in interactions of the SPS proton beams with the target of the SHiP experiment. The SHIP experiment will be able to search for new long-lived particles produced in a 400 GeV/c SPS proton beam dump and which travel distances between fifty metres and tens of kilometers. The SHiP detector needs to operate under ultra-low background conditions and requires large simulated samples of muon induced background processes. Through the use of Generative ...
