Maximizing power harvest in a distributed photovoltaic system
2012 IEEE International Symposium on Circuits and Systems, 2012In a conventional grid-tied distributed photovoltaic (PV) system, individual power optimizers are used for modules connected in series to maximize energy harvest from each module. However each power optimizer lacks information on the string voltage and thus an inverter is designed to control the string voltage. This scheme is not guaranteed to have the

Photovoltaic powered regulated cathodic protection system
Solar Energy, 1994Abstract The objective of a cathodic protection system is to protect metallic structures against corrosion. To achieve this, a sacrificial anode is connected to the protected structure (which acts as a cathode) through a d.c. power supply. To stop the corrosion, the protected structure requires a constant current.

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.

Stability analysis of power systems with photovoltaic generators
2016 IEEE 55th Conference on Decision and Control (CDC), 2016This paper analyzes the stability of a power system in which a synchronous generator and a photovoltaic (PV) generator supply the power to an infinite bus. The infinite bus corresponds to a large system to which the two generators are connected. The problem considered here is to investigate the existence of the equilibrium points of the system and ...

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

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
