Photovoltaic powered regulated cathodic protection system

Solar Energy, 1994
Abstract 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.

Active power control of photovoltaic power systems

2013 1st IEEE Conference on Technologies for Sustainability (SusTech), 2013
Historically, electric power system operators have seen photovoltaic (PV) power systems as potential sources of problems due to intermittency and lack of controllability. However, the flexibility of power electronic inverters allows PV to provide grid-friendly features including volt-VAR control, ramp-rate control, high-frequency power curtailment, and

Maximum power tracking for photovoltaic power system

Conference Record of the 2002 IEEE Industry Applications Conference. 37th IAS Annual Meeting (Cat. No.02CH37344), 2003
The electric power supplied by a photovoltaic power generation system depends on the solar radiation and temperature. Designing efficient PV systems heavily emphasizes tracking the maximum power operating point. This work develops a novel three-point weight comparison method that avoids the oscillation problem of the perturbation and observation ...

Photovoltaic systems for powering greenhouses

2011 International Conference on Clean Electrical Power (ICCEP), 2011
In the paper it is shown that grid-connected PV-plants can be considered and profitably used for powering greenhouses. In fact, in a PV-plant to be installed in a greenhouse, PV-modules can be simply and fully integrated on the greenhouse coverage so allowing to obtain the maximum government economical incentive for generating electricity, also ...

Communication system using photovoltaic power

Energy Conversion and Management, 2000
Abstract An alternative photovoltaic powered communication system is proposed to replace the conventional system of loading and unloading signals on 400 kV transmission lines using expensive current transformers. A battery charge–discharge controller from photovoltaic sources is described, which operates from a 12 V array to power VHF or optical ...
