In this paper. the design aspects of low-voltage DG-PV units were investigated in order to comply with LVRTC requirements. The theoretical analysis revealed how the impedance of the DG units affects the bus voltages of the distribution network after a fault occurrence. Moreover. the concept of voltage selectivity is defined. …

The properties of the most recent CIGS solar cells with conversion efficiencies up to 21.7% show a remarkable increase in Jsc. a high Voc level and improved FF when compared to former record results. The significant increase in Jsc can be explained by an optical gain through a thinner CdS …

In this paper. a novel approach has been proposed to manage and improve the quality of the grid power using a WECS equipped by a DFIG. The RSC is controlled in such a way to manage between production of maximum active power and power quality improvement without any over-rating. The …

This paper has presented a novel control of an existing gridinterfacing inverter to improve the quality of power at PCC for a 3-phase 4-wire DG system. It has been shown that the grid-interfacing inverter can be effectively utilized for power conditioning without affecting its normal operation of real power transfer. …

Fixed speed and variable speed wind generator models for power system dynamics and transient stability analysis were presented. The models are valid for the simulation of system faults and power fluctuations resulting from wind-turbulence. For estimating wind-turbulence in wind farms a stochastic turbulence model was presented considering rotational sampling. tower …

In this paper. a novel fast short circuit current detection technique is proposed for PV inverter based DGs. The proposed short circuit current detector is based on the evaluation of the slope (d dt) and magnitude of the PV inverter current. As soon as it detects a fault that is …

A comprehensive system leveraging mobile and RFID technologies. aggregation middleware and an aggregated charge-scheduling algorithm that effectively schedules charging and V2G operations for cost savings and peak load reduction has been presented. Intelligently scheduled charging yields a cost savings of 7% for enterprise commuters and 10% for drivers with variable …
