The goal of this paper is to study the impact of the dynamic nature of bus voltage magnitudes and phase angles, which constitute the state of the power system, on the phasor measurement unit (PMU) placement problem. To facilitate this study, the placement problem is addressed from the perspective of the electrical structure which, unlike existing work on PMU placement, accounts for the sensitiv...

This paper summarizes the utility of some low-power design (LPD) methods based on architectural and implementation modifications, for FPGA based systems. Power consumption is becoming one of the mayor design trade-off in today electronic. In this work, the contribution of spurious transitions to the overall consumption is evidenced and main strategies for its reduction are analyzed. Empirical r...

Accurate modeling of the wind energy conversion system is necessary to design and implementation of the control loop for the generator and the frequency converter, in order to extract maximum power from the wind and to investigate the effects of interconnection between wind farms and power system. In this paper the combination of a permanent magnet synchronous generator loaded with a diode rect...

the modern state is a renewable and evolutionary phenomenon and it cannot be evaluated so that it has single cause. therefore none of the fields of the human sciences alone cannot fully explain the emergence of the modern state without interaction with other disciplines. political superstructure in various countries, primarily influenced by the social and cultural systems of communities as the ...

The widely used method of least squares for state estimation is revisited. The commonly used least squares philosophy is based on the L 2 Hölder norm. The L 1 and L 8 norms are considered for applications in power engineering. The effects of outliers in measurements and multicolinearity on state estimation are studied. An application in parameter estimation for synchronous generators is given a...
