Modal analysis of power systems to mitigate harmonic resonance considering load models
Esmaili, Masoud; Ali Shayanfar, Heidar; Jalilian, Alireza - In: Energy 33 (2008) 9, pp. 1361-1368
To detect and alleviate harmonic resonance in a power system have been a delicate issue. In this paper, the effect of load modeling on resonance behavior of power systems employing eigenvalue sensitivity analysis is investigated. The most influencing parameters to mitigate resonance modes are...

Cycles in basic innovations
Franses, Philip Hans; de Groot, de Groot, E.A. - Faculteit der Economische Wetenschappen, Erasmus … - 2005
Basic innovations are often believed to be the drivers of economic growth. It has been widely documented that economic growth follows cyclical patterns of varying length. In this paper we examine if such patterns are also present in basic innovations. For an annual time series of count data...
