This letter applies a feedforward neural network trained in an unsupervised fashion to the problem of optimizing transmit powers centralized radio access networks operating on cell-free basis. Both uplink and downlink are considered. Various objectives entertained, some leading convex formulations that do not. In all cases, performance proposed procedure is very satisfactory and, terms computat...

When power systems are expanded and connected together with weak tie lines, the low-frequency oscillations are increased and the stability margin of the power system decreases. Therefore, when designing the transmission system to be used, it is necessary to maintain the dynamic stability of the power system, and to make sure to have the most possible stability margin. SSSC is a FACTS device con...

The Sliding mode control theory is applied to a sinusoidal output voltage boost inverter with linear load. The boost inverter is intended to be used in UPS design, whenever an AC voltage larger than the DC link voltage is needed, with no need of a second power conversion stage. Operation, control strategy, simulation and experimental results are'included in this paper.

Abstract— Reduction of the Harmonics is one of the major needs for Power System & it is demanded that source should provide a balanced & pure sinusoidal three-phase voltage of constant amplitude to the loads. But, due to excessive use of Power Electronics, a complex power quality problem evolved characterized by the voltage and current harmonics. Active power filters have been developed to solv...

The doubly-fed generators (DFIG) have clear superiority for the applications of large capacity and limited-range speed control case due to the partially rated inverter, lower cost and high reliability. These characteristics enable the doubly-fed wound rotor induction machine to have vast applications in wind-driven generation.In this paper Combined Vector and direct power control (CVDPC) strate...
