SVC Placement in Unbalanced Distribution Network to Reduce the Neutral Lines Current and Ohmic Losses Using Intelligent Optimization Algorithms
Distribution Network (DN) unbalancing and their unfavorable effects such as energy losses is an important challenge in electrical engineering. The system unbalancing problem is highly regarded due to increasing energy costs in DN. In this paper, the use of SVC (Static Var Compensation) is to improve the unbalancing and reducing the energy losses in DN. To handle power flow procedure, a novel ci...
متن کاملA Comparison between Radiation and Ohmic Losses in Highly-conducting Interconnects for High-speed Applications
This paper deals with the problem of estimating the losses in highly-conducting wires, in a frequency range where the transverse dimension is comparable to the signal wavelength. In this case the standard transmission line model fails since it cannot predict high-frequency effects like radiation in the transverse plane. Here we use a recently proposed enhanced transmission line model which, alt...
متن کاملExchanging Ohmic Losses in Metamaterial Absorbers with Useful Optical Absorption for Photovoltaics
Using metamaterial absorbers, we have shown that metallic layers in the absorbers do not necessarily constitute undesired resistive heating problem for photovoltaics. Tailoring the geometric skin depth of metals and employing the natural bulk absorbance characteristics of the semiconductors in those absorbers can enable the exchange of undesired resistive losses with the useful optical absorban...
متن کاملMinimization of Ohmic losses for domain wall motion in a ferromagnetic nanowire.
We study current-induced domain-wall motion in a narrow ferromagnetic wire. We propose a way to move domain walls with a resonant time-dependent current which dramatically decreases the Ohmic losses in the wire and allows driving of the domain wall with higher speed without burning the wire. For any domain-wall velocity we find the time dependence of the current needed to minimize the Ohmic los...
متن کاملRipple Current Reduction by Optimizing Load Dependend Switching Losses Using Adaptive Current Control
In modern inverter fed drive applications the power semiconductors used are typically designed to operate at their maximum thermal operation conditions. Semiconductors worst case thermal considerations in general define the uppermost inverter switching frequency dependent on maximum load current. Fixing this frequency to a constant value, the drive will not be operated with best possible perfor...
