This paper addresses day-ahead unit commitment with significant wind penetration as a multi-objective optimization problem in an uncertain environment considering system operation cost and reliability as the multiple conflicting objectives. The uncertainties occurring due to thermal unit outage, load forecast error and wind forecast error are efficiently incorporated using expected energy not served...
In the process of maintainability allocation of numerical control (NC) machine tools, many influence factors should be considered, and some of which are difficult to analyze quantitatively. In order to solve the above-mentioned problem, this paper proposed a new method for maintainability allocation, which comprehensively applied interval analysis, fuzzy comprehensive evaluation, and analytic hierarchy...
This paper presents a new comprehensive solution for maintenance scheduling of generating units in deregulated environments by applying an independent market, based on Genetic Algorithm (GA) and Monte-Carlo Simulation (MCS). In a deregulated environment each Generation Company (GENCO) desires to optimize the payoffs while independent system operator (ISO) has its reliability solicitudes. Mostly, these...
This paper proposes the method to predict a reliability index of power distribution feeders in the central area of Provincial Electricity Authority (PEA) of Thailand. Using the Weibull distribution, the time to failure data during 2002 2009 is analyzed over moving 4-year periods to determine the failure rates associated with protective devices (Breakers, Reclosers and Fuses). The next year failure...
This paper proposes a new solution for maintenance scheduling in deregulated power market by applying an independent market for maintenance scheduling based on game theory. Maintenance scheduling is one of the main issues in restructured power electricity markets, because each generation company desires to maximize its own payoffs and ISO has its own reliability and security concerns that mostly,...
Tunable diode laser spectroscopy (TDLS) can only be successfully implemented if a number of system characterization procedures and critical parameter measurements can be made accurately. These include: application of a wavelength/frequency scale to the signals recovered in time; measurement of the frequency dither applied to the laser; measurement of the relative phase between the laser power modulation...
