Developing a Mobile Stand Alone Photovoltaic Generator
Energy Conversion and Management, 2006This paper describes a recent work developed to create a mobile stand alone photovoltaic generator that can be easily relocated in remote areas to evaluate the feasibility of photovoltaic energy applications. A set of sensors were installed to monitor the electric current and voltage of the energy generated, the energy stored and the energy used by the

Efficiency Optimization in Stand-Alone Photovoltaic Pumping System
Renewable Energy, 2012Solar photovoltaic energy is a very promising and important sustainable global energy source. Despite its many advantages, it is still an expensive alternative, which explains the fact that it has not yet became commercially popular. Studies already show that the investments in such systems are paid back.

Costing of a stand-alone photovoltaic system
Energy, 1998We have used a life-cycle cost analysis for a stand-alone photovoltaic system with and without an auxiliary engine generator. Because of different published cost calculations, we apply average values or new estimates in the analysis based on examinations of component lifetimes, maintenance operations, fuel consumption, components costs, percentage of ...

The regulation of stand alone photovoltaic systems
Conference Proceedings., Eleventh International Telecommunications Energy Conference, 2003The author considers the control optimization of stand-alone PV (photovoltaic) systems in order to maximize the charging of the battery. The standard control algorithm based on the voltage of the battery as a charge indicator is replaced by an intelligent processor which observes the battery status at the end of the night to make a decision about the ...

Supervisory control for stand-alone photovoltaic systems
2013 Brazilian Power Electronics Conference, 2013This paper proposes a supervisory controller applied to a stand-alone photovoltaic system with a centralized dc bus. The system is comprised of three independently closed-loop controlled converters, whose references and operation modes are defined by the supervisory system.
