Current-Shared Photovoltaic Power System
The 2010 International Power Electronics Conference - ECCE ASIA -, 2010A novel high efficiency Current-Shared Photovoltaic Power System (CS-PPS), mainly constructed by the Maximum Power Point Tracking and Power Conditioning System (MPPT-PC), is proposed in this paper. The proposed MPPT-PC can track the MPPT and regulate the load energy condition at the same time for increasing the circuit efficiency and providing stable ...

The power factor control system of photovoltaic power generation system
Proceedings of the Power Conversion Conference-Osaka 2002 (Cat. No.02TH8579), 2003The photovoltaic power generation system has a great future as clean energy instead of fossil fuel, which has many environmental problems such as exhausted gas or air pollution. In a utility interactive photovoltaic generation system, a three phase inverter is used for the connection between the photovoltaic array and the utility. This paper presents a

Power Conditioning Unit for Photovoltaic Power Systems
1981This paper describes a Power Conditioning Unit (PCU) for solar photovoltaic energy collection system. The PCU rated 50/62,5 kVA, 50/60 Hz, 3-phase, 4-wire has the capability to operate in a stand-alone mode or paralleled with a commercial 3-phase utility power line. The quality of power is compatible with that of the electric utilities.

Power Optimizing of Solar Photovoltaic Systems
Advanced Materials Research, 2012Efficient energy yield is a major concern in solar photovoltaic (PV) systems. This paper describes a distributed control system to optimize the power output of the PV systems. The PV systems contain many PV modules. And every PV module has a monitoring and control network node. The communication data are successfully transmitted using a low-cost ZigBee

Terrestrial concentrating photovoltaic power system studies
Solar Energy, 1978Abstract Studies aimed at defining the role of sunlight concentration in reducing the cost of electrical energy generated by terrestrial photovoltaic systems are described. These studies use computer modelling to (a) compare silicon cells and gallium arsenide cells in concentrating systems, (b) investigate the operation of photovoltaic systems in low

Photovoltaic power system modeling and simulation
2016 IEEE International Conference on Power and Renewable Energy (ICPRE), 2016In this paper, the model of photovoltaic panel is built by analyzing the variation of open circuit voltage and short circuit current caused by ambient temperature and radiation intensity fluctuation. Also the current-voltage and power-voltage curves in different radiation intensity and ambient temperature are showed.

A photovoltaic-powered pumping system
2011This thesis studies the optimal design for a photovoltaic-powered medium-head (30 meters) water pumping system, with the emphasis on improving the efficiency and reducing the maintenance requirements of the electrical subsystem. The reduction of maintenance requirements is realized by replacing the conventional brush-type permanent magnet dc motor with
