due to the increasing interest on renewable sources in recent years, the studies on integration of distributed generation to the power grid have rapidly increased. in order to minimize line losses of power systems, it is crucially important to define the size and location of local generation to be placed. minimizing the losses in the system would bring two types of saving, in real life, one is ...

In this paper, a new cascaded multilevel inverter by capability of increasing the number of output voltage levels with reduced number of power switches is proposed. The proposed topology consists of series connection of a number of proposed basic multilevel units. In order to generate all voltage levels at the output, five different algorithms are proposed to determine the magnitude of DC volta...

A molecule containing a nitroamine redox center (2'-amino-4-ethynylphenyl-4'-ethynylphenyl-5'-nitro-1-benzenethiol) was used in the active self-assembled monolayer in an electronic device. Current-voltage measurements of the device exhibited negative differential resistance and an on-off peak-to-valley ratio in excess of 1000:1.

One of the most important objectives of smart distribution networks (SDNs) is to achieve a secure and reliable network. This can be realized by optimal operation in the presence of active power sources such as the distributed generations (DGs), reactive power sources such as switched capacitor bank (SCB), active loads such as the demand response program (DRP), and various network management str...

A criterion for redox voltage tuning (0.96-2.96 V vs. Li(+)/Li) was derived from DFT calculations on quinoneazine and analogues (C/O replacing N). As rationalized through spin-charge distributions and energetic criteria, high-low voltage implying a bridge with delocalized-localized bond nature mainly originates from ring stabilization. Established guidelines serve to propose optimal derivatives.

A new output structure for class E power amplifier (PA) is proposed in this paper. A series LC resonator circuit, tuned near the second harmonic of the operating frequency is added to the output circuit. This resonator causes low impedance at the second harmonic. The output circuit is designed to shape the switch voltage of the class E amplifier and lower the voltage stress of the transistor. T...

The application of voltage reduction in medium and low grids to reduce peak power demand or energy consumption has been implemented since the 1980s using several approaches. Conservation Voltage Reduction (CVR), as one such approach, uses a control device increase setpoint on busbar, thereby reducing increasing amount active reactive supply network. regulation for CVR is always according establ...
