System modeling and stability analysis is one of the most important issues of inverter-dominated microgrids. It is useful to determine the system stability and optimize the control parameters. The complete small signal models for the inverterdominated microgrids have been developed which are very accurate and could be found in literature. However, the modeling procedure will become very complex...

The power system stabilizer is used to damp out the low frequency oscillations that improve the small signal stability of the power system. If ignored these low frequency oscillations may lead to cascaded failure of the complete power system. This paper presents the comparative study of conventional power system stabilizer (CPSS) with newly proposed Adaptive Fuzzy Logic Controlled Power System ...

The objective of this paper is to study the small-signal stability of congested TCP networks. The starting point for this analysis is a fluid model describing the interaction of TCP-controlled traffic with congested routers. Assuming integral action in the active queue management scheme, we compute the network’s equilibrium point about which we determine the network’s small-signal dynamics. Spe...

The paper investigates the small-signal stability of a 270V DC power system for a more electric aircraft, which employs switched reluctance generator technology and multiple distributed power electronic converters for flight control surface actuation, environmental control, and numerous DC and AC loads. Non-linear state space models for the complete system have been established and the eigenval...

In this work, we obtain sufficient conditions for the “stability” of our recently proposed algorithms, modified-CS (for noisy measurements) and Least Squares CS-residual (LS-CS), designed for recursive reconstruction of sparse signal sequences from noisy measurements. By “stability” we mean that the number of misses from the current support estimate and the number of extras in it remain bounded...

A synchronous generator may sometimes be able to withstand a large impact but it may fail to retain synchronism under a small impact due to growing oscillations, leading to instability. This is called dynamic instability. It occurs for specific operating conditions and network configurations, particularly in presence of fastacting excitation control. The paper presents techniques of small signa...

In this paper, a synchronized control strategy of double fed induction generator that can provide reserve capability and primary frequency support for microgrid is firstly developed. The microgrid based small signal stability performance is investigated under multiple operating conditions. The effect of three categories of key controller parameters on dominant eigenvalues is studied by sensitiv...
