Doubly-fed induction generator (DFIG) based wind turbines with traditional maximum power point tracking (MPPT) control provide no inertia response under system frequency events. Recently, the DFIG wind turbines have been equipped with virtual inertia controller (VIC) for supporting power system frequency stability. However, the conventional VICs with fixed gain have negative effects on inter-ar...

The avian pineal gland contains circadian oscillators that regulate the rhythmic release of melatonin. We have developed a dissociated chick pineal cell culture system in order to begin a cellular analysis of this vertebrate circadian oscillator. Dissociated pineal cells maintained in cyclic light conditions (LD 12:12) released melatonin rhythmically. The release of melatonin was elevated durin...

The interline power flow controller (IPFC) is a concept of the FACTS controller for series compensation which can inject a voltage with controllable magnitude and phase angle among multi lines. This paper proposes a novel IPFC-Based Damping Neuro-control scheme using PSO for damping oscil‌la‌t‌i‌o‌ns in a power system to improve power system stability. The add‌i‌tion of a supplementary controll...

This paper proposes a robust control framework for power system stabilizer to improve system dynamic performance based on model predictive control (MPC). The effectiveness of the proposed power system stabilizer is validated by a simple power system composed of a synchronous generator connected to an infinite bus through a transmission line. A comparison between power system responses at variet...

We investigate both experimentally and theoretically disorderinduced damping of Bloch oscillations of Bose–Einstein condensates in optical lattices. The spatially inhomogeneous force responsible for the damping is realized by a combination of a disordered optical and a magnetic gradient potential. We show that the inhomogeneity of this force results in a broadening of the quasimomentum spectrum...

FACTS technology has considerable applications in power systems, such as; improving the steady stateperformance, damping the power system oscillations, controlling the power flow, and etc. STATCOM is oneof the most important FACTS devices used in the parallel compensation, enhancing transient stability andetc. Since three phase fault is widespread in power systems, in this paper STATCOM is used...

Complex nonlinear phenomena are investigated in a basic power system model of the single-machine-infinite-bus (SMIB) with a synchronous generator modeled by a classical third-order differential equation including both angle dynamics and voltage dynamics, the so-called flux decay equation. In contrast, for the second-order differential equation considering the angle dynamics only, it is the clas...

When we research the suppression problem of subsynchronous oscillation based on time domain simulation method, we find the appropriate parameters for phase compensation and amplitude gaining links are important to the damping effect of the additional damping controllers, supplementary excitation damping controller(SEDC) and subsynchronous supplementary damping controller(SSDC). Some scholars at...
