The increasing presence of wind power in power systems will likely drive the integration of large wind farms with electrical networks that are series-compensated to sustain large power flows. This may potentially lead to subsynchronous resonance (SSR) issues. In this paper, a supplementary controller on the grid-side converter (GSC) control loop is designed to mitigate SSR for wind power system...

The simplest aerodynamic model of horizontal-axis wind turbines is the blade element momentum theory, which assumes that blades behave as airfoils, but a correct two-dimensional representation an infinite cascade lifting bodies. This study analyzes conventional and impulse forms forces on cascades airfoils at spacings pitch angles typical turbine applications. OpenFOAM software was used to simu...

This paper proposes a tabu search based method for optimal allocation of FACTS in distribution systems. Distributed generation is wildly spread to smooth operation and planning in power systems so that wind power generation units are connected to distribution systems. Although they contribute to the improvement of operation and planning in distribution systems, they often bring about difficulti...

We explore a mechanism, entirely new to the fast solar wind, of electron heating by lower hybrid waves to explain the shift to higher charge states observed in various elements in the fast wind at 1 A.U. relative to the original coronal hole plasma. This process is a variation on that previously discussed for two temperature accretion flows by Begelman & Chiueh. Lower hybrid waves are generated...

abstract in general, garmesh wind in rasht province increases the temperature by 9°c and reduces relative humidity by 47%. the direction of prevailing wind during the garmesh wind is southern and its average speed increases by 2 m/s to 5 m/s. the highest frequency of garmesh wind occurs at 09 and 12 utc in december and january. the occurrence of this phenomenon substantially increases the horiz...
