Evaluation of generation efficiency and voltage deviation in residentail clustered PV voltage control

2011 37th IEEE Photovoltaic Specialists Conference, 2011
Installation zero-emission power sources, including photovoltaic power systems (PV), is necessary to cut greenhouse gasses to reduce global warming. In Japan, the target capacity for installed PV in 2020 has been set at 28 GW, which is 20 times the 2005 capacity. PV should be installed in 70 percent of new houses to reach this target.

Maximum photovoltaic access capacity considering voltage deviation

2017 2nd International Conference on Power and Renewable Energy (ICPRE), 2017
Distributed PV has developed rapidly with the advantages of less geographical limit, large capacity, cleanness and pollution-free. And the increasing grid-connected PV capacity also causes an important impact on the voltage of distribution network. Aimed at the maximum photovoltaic access capacity, this paper studied two typical topologies of open ...

Influence of Threshold Voltage Deviations on 90nm SRAM Core-Cell Behavior

16th Asian Test Symposium (ATS 2007), 2007
Nanoscaled SRAMs are now becoming more and more prone to device parameter deviations. In this paper, we consider threshold voltage (Vt) deviations in 6T core-cells designed with 90 nm technology. Static faults (transition and read destructive) but also dynamic faults (dynamic read destructive) are obtained as resulting faulty behaviors.

Voltage Stability Index and Voltage Deviation Improvements using Intelligent Algorithms for Capacitor Sizing and Placement

2018 IEEE PES Asia-Pacific Power and Energy Engineering Conference (APPEEC), 2018
Voltage stability of each bus of an electrical distribution system along with the deviation of voltage magnitudes from the tolerance limits are two of the most common but significant issues in the present day distribution networks. This work is carried out with the objective of identifying the optimal location and ideal sizes of capacitors to be used ...

Influence of Neutral-Point Voltage Deviation of PWM Converter on Insulation Monitoring in Medium-Voltage Networks

IEEE Transactions on Power Delivery, 2017
Insulation monitoring is crucial to personal safety and equipment operation in the power distribution system. Recently, with the rapid development of distributed generators, the three-phase voltage-source PWM converter (VSC) is widely used as the bidirectional interface between the dc microgrids and the distribution networks.

Voltage deviation of POL converter with two-stage output filter

2011 Twenty-Sixth Annual IEEE Applied Power Electronics Conference and Exposition (APEC), 2011
Obtaining a very low output filter has become a vital requirement for most of telecommunications applications. One from the common and practical ways to obtain a low output voltage ripple is to add a second stage LC filter. However, this creates a problem for the converter dynamics.
