A Decentralization Method for Hybrid State Estimators
Göl, Murat (Institute of Electrical and Electronics Engineers (IEEE), 2018-03-01)
Hybrid state estimation determines the states of systems monitored both by conventional SCADA measurements and PMUs. This paper proposes a decentralization method in order to improve the computational performance of hybrid state estimators with minimum loss of accuracy. The proposed method utilizes sensitivity matrix that relates measurement errors to state estimates in order to form the so-called isolated bus groups and observable subislands. Although the proposed decentralization method can be applied to ...

The concept of partially observable Markov decision processes was born to handle the problem of lack of information about the state of a Markov decision process. If the state of the system is unknown to the decision maker then an obvious approach is to gather information that is helpful in selecting an action, This problem was already solved using the theory of Markov processes. We construct a nonlinear programming model for the same problem and develop a solution algorithm that turns out to be a policy ite...
A two-level iterative scheme for general sparse linear systems based on approximate skew-symmetrizers
Mehrmann, Volker; Manguoğlu, Murat (2021-01-01)
We propose a two-level iterative scheme for solving general sparse linear systems. The proposed scheme consists of a sparse preconditioner that increases the norm of the skew-symmetric part relative to the rest and makes the main diagonal of the coefficient matrix as close to the identity as possible so that the preconditioned system is as close to a shifted skew-symmetric matrix as possible. The preconditioned system is then solved via a particular Minimal Residual Method for Shifted Skew-Symmetric Systems...
A Mixed integer programming method for integrated discrete time-cost trade-off and manpower resource leveling problem
Tatar, Ali Can; Sönmez, Rifat; Atan, S. Tankut; Department of Civil Engineering (2016)
Construction projects have to meet all of the objectives of scope, quality, schedule, budget simultaneously. These objectives, however, cannot be considered as independent of each other. For example, an increase in direct resources will usually lead to shorter activity durations. A shorter project duration results in lower indirect costs, whereas the additional resources cause an increase the project’s direct costs, in general. This phenomenon is defined as time-cost trade-off problem (TCTP). Nevertheless, ...
A Simulink Nonlinear Model for LSRA Control Scheme Analysis
Pestana, Luis M.; Calado, M. do Rosario A.; Mariano, Silvio S. (2011-09-10)
This paper addresses the nonlinear model implementation of a Linear Switched Reluctance Actuator (LSRA) in the MATLAB/ Simulink simulation package. The model is based in an already implemented motor model for the rotating machine, which was improved and adopted to be applied in the analysis of a linear actuator. Both the magnetic information from experimental data and results obtained from Finite Element Analysis (FEA) were used to perform that study. The model is used in the assessment of several control s...
