Currently available power storage systems, such as those used to supply power to microelectronic devices, typically consist of a single centralized canister and a series of wires to supply electrical power to where it is needed in a circuit. As the size of electrical circuits and components become smaller, there exists a need for a distributed power system to reduce Joule heating, wiring, and t...

one of the new methods for electrical powering of the bridge health monitoring systems is applying energy harvesting systems using bridge vibration. in this method, the piezoelectric material is employed for converting mechanical energy into electrical energy. the advantage of this method is based on not implementing the battery charging system. in previous research, some studies have been done...

in this paper, a study and design of energy conservation actions and the obtention of energy efficiency titles, according to the italian ministerial decree 20th july 2004, applied to lighting and electrical systemsin a school district managed by perugia province (italy), is presented.specifically, the analysis regarded the replacement of neon lamps with high efficiency ones, and the power facto...

voltage fluctuation is one of the important types of power quality aspects originated from heavy fluctuating loads. this phenomenon can influence the behavior of induction motors, produce excessive vibration and increase the ohmic losses. in this paper a simplified model to evaluate the electrical characteristics of three phase induction motors under voltage fluctuation conditions will be prese...

in our present paper, we present the effectiveness of the controller's electrical power f low Universal (unif ied power f low controller UPFC) w ith the choice of a control strategy. To evaluate the performance and robustness of the system, w e proposed a hybrid control combining the concept of neural networks with conventional regulators vis-à-vis the changes in characteristics of the transmis...

Power quality issues are becoming a serious concern for electrical power users considering the negative influence that these phenomena can have on the electrical equipment and the utility bill. That is why more solutions are required for measuring the power quality parameters. This paper presents a lowcost approach based on an inexpensive RISC microprocessor and frequency analysis for constant ...

We investigate the performance of a linear electromechanical oscillator as an energy harvester of finite-bandwidth random vibrations. We derive exact analytical expressions for the net electrical power and the efficiency of the conversion of the power supplied by the noise into electrical power for arbitrary colored noise. We apply our results to the important case of exponentially correlated n...

The use of renewable energy in power generation and sudden changes in load and fault in power transmission lines  may cause a voltage drop in the system and challenge the reliability of the system. One way to compensate the changing nature of renewable energies in the short term without the need to disconnect loads or turn on other plants, is the use of renewable energy storage. The use of ener...
