Most countries have automatic rules in their tax-and-transfer systems that are intended, at least partly, to stabilize economic fluctuations. We measure how effective these automatic stabilizers are in a modern business-cycle model. We consider the effect of the stabilizers on aggregate demand, on the incentives to work and save, and on the distribution of income across households, all of which...

This paper proposes a novel optimization technique for simultaneous coordinated designing of power system stabilizer (PSS) and static VAR compensator (SVC) as a damping controller in the multi-machine power system. PSO and chaos theory is hybridized to form a chaotic PSO (CPSO), which reasonably combines the population-based evolutionary searching ability of PSO and chaotic searching behavior. ...

this paper introduces an indirect adaptive fuzzy sliding mode controller as a power system stabilizer for damping local and inter-area modes of oscillations of multi-machine power systems. this controller is designed based on the combination of sliding mode controller and the fuzzy logic systems. the fuzzy systems are used to approximate the unknown functions of power system model. generator sp...

A variety of factors are causing an increase of slow frequency oscillations in power systems. These oscillations reduce the stability of the system, limit power transfers, and can potentially lead to loss of synchronism and widespread blackouts. These oscillations typically involve variables from distant areas accross the system; therefore, conventional local damping controllers such as power s...

The statistical operation is necessary to validate the analytical procedure since most important common comparison of result data quantify accuracy and precision. In this paper, a process proposed ensure impact power system stabilizers (PSSs) in 202-bus, 40-machine MEPE test system. eigenvalue analysis utilized for detecting lowest damping modes evaluating ratio oscillation, these are applied a...

The design of a conventional power system stabilizer (PSS) based on linearized model cannot guarantee its performance in practical operating, so some intelligent techniques have been used. However, the parameters cannot update online in most of these mehods, thus the performance cannot be further improved. This paper adopts the design method of adaptive neural-fuzzy based power system stabilize...

Power system oscillation is a serious threat to the stability of multimachine power systems. The coordinated control of power system stabilizers (PSS) and thyristor-controlled series compensation (TCSC) damping controllers is a commonly used technique to provide the required damping over different modes of growing oscillations. However, their coordinated design is a complex multimodal optimizat...
