Zeolites have been used in many more industrial applications; the most recent one that has caused a big revolution in control of NOx reduction is as selective catalytic reduction (SCR) catalysts to control auto emissions. The special porous structure lets the zeolite material suitable for selecting the molecules of certain size. Unfortunately, this porous property coupled with a charge imbalanc...

Voltage control is one of the imperative issues in the smart distribution control system. While traditional distribution network is equipped with communication and monitoring equipment, the online voltage control can be perfectly achieved. With using these smart grid technologies, the distribution voltage control schemes should carry out intelligently and cover the undesirable effect of high pe...

This paper presents exhaustive review of various concept of voltage instability, main causes of voltage instability, classification of voltage stability, dynamic and static voltage stability analysis techniques, modeling, shortcomings, in power systems environments. It also reviews various current techniques/methods for analysis of voltage stability in power systems through all over world. This...

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...

Low inertia, nonlinearity and a high level of uncertainty (varying topologies operating conditions) pose challenges to microgrid (MG) systemwide operation. This paper proposes an online adaptive Koopman operator optimal control (AKOOC) method for MG secondary voltage frequency control. Unlike typical data-driven methods that are data-hungry lack guaranteed stability, the proposed AKOOC requires...

Low voltage microgrids including sensitive loads often face unbalanced load conditions. Therefore, a compensation procedure should be carried out in order to balance and restore sensitive load’s voltage. In this paper, an effective voltage control strategy has been proposed for the autonomous operation of microgrids, under unbalanced load conditions.  The proposed strategy balances single-phase...

This paper presents a method to control both the dc boost and the ac output voltage of Z-source inverter using neural network controllers. The capacitor voltage of Z-source network has been controlled linearly in order to improve the transient response of the dc boost control of the Z-source inverter. The peak value of the line to line ac output voltage is used to control and keep the ac output...
