Power quality issues are becoming a major concern of today's power system engineers. Shunt active power filter (SAPF) is one of the effective means for harmonic current compensation in electrical power system. The performance and dynamic characteristics of a three-phase SAPF with a simple control algorithm is presented and analyzed in this paper. This algorithm operates at fixed switching frequ...

As a form of energy storage with high power and efficiency, flywheel system performs well in the primary frequency modulation grid. In this study, three-phase permanent magnet synchronous motor was used as drive system, simulation study on control strategy conducted based wind power. The speed current double closed-loop start-up phase, double-closed-loop were compensation phase. model reference...

The paper deals with the comparison study of harmonic detection methods for a shunt active power filter. The %THD and the power factor value at the PCC point after compensation are considered for the comparison. There are three harmonic detection methods used in the paper that are synchronous reference frame method, synchronous detection method, and DQ axis with Fourier method. In addition, the...

This paper proposes a novel transmit power allocation combined with the phase compensation for OFDM system. This technique consists of adapting the power allocation and the phase compensation in the frequency domain depending on the channel variations. Optimization process is based on the optimality of the global Bit Error Rate (BER). Simulation results show significant performance gains can be...

This paper first presents a simple control technique for active filters to compensate current harmonics and reactive power of nonlinear loads. This method is usable for both single –phase and three –phase systems. Then a new method for load balancing and reactive power compensation for unbalanced sinusoidal load currents is presented. Finally by combination of two methods an active filter contr...

The wind suddenly blown to the side of car (i.e, cross-wind effect) is considered as one major lateral disturbances, which causes unstable motion vehicle and persistent driving fatigue for driver who tracks desired travel path. In particular, a commercial having large area greatly affected by this effect. Therefore, many related automotive/car manufacturers still wish equip their Advanced Drivi...

A coordinated-control scheme with a compensator for a fossil-fuel power plant is presented. The compensator is intended to reduce the interaction effects among the control loops to ease control during wide-range normal operating conditions. Placed between the controllers and the power plant, the compensator only introduces compensation factors among the control signals; preserving the direct co...

We investigate CEO compensation for completing M&A deals. We find that CEOs who have more power to influence board decisions receive significantly larger bonuses. We also find a positive relation between bonus compensation and measures of effort, but not between bonus compensation and deal performance. CEOs with more power also tend to engage in larger deals relative to the size of their own fi...

In this paper, an adaptive control strategy is proposed for the inverters of renewable energy source (RES) to simultaneously control the load voltage, grid current and the amount of instantaneous injected power to the grid in the presence of grid voltage distortions and nonlinearity of load current. In the proposed control strategy, the power quality of the local load can be settled based on th...
