Efficiency optimization in stand-alone photovoltaic pumping system

Corrêa, Tomás Perpétuo; Seleme, Seleme Isaac; Silva, … - In: Renewable Energy 41 (2012) C, pp. 220-226

Solar 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...

Input output feedback linearization control and variable step size MPPT algorithm of a grid-connected photovoltaic inverter

Lalili, D.; Mellit, A.; Lourci, N.; Medjahed, B.; … - In: Renewable Energy 36 (2011) 12, pp. 3282-3291

In this paper, the power factor of a grid-connected photovoltaic inverter is controlled using the input output Feedback Linearization Control (FLC) technique. This technique transforms the nonlinear state model of the inverter in the d–q reference frame into two equivalent linear subsystems,...

Applying grid-connected photovoltaic system as alternative source of electricity to supplement hydro power instead of using diesel in Uganda

Twaha, Ssennoga; Idris, Mohd Hafizi; Anwari, Makbul; … - In: Energy 37 (2012) 1, pp. 185-194

Uganda’s electricity sector for long has been depending on hydro as a base power source. Diesel is currently the second source of electricity which supplements the hydro power. The use of diesel has some implications; first, the price of fuel is high and therefore the energy produced is also...

A new estimation method of irradiance on a partially shaded PV generator in grid-connected photovoltaic systems

Drif, M.; Pérez, P.J.; Aguilera, J.; Aguilar, J.D. - In: Renewable Energy 33 (2008) 9, pp. 2048-2056

A new method for estimating the irradiance on a partially shaded photovoltaic generator system is proposed. The basic principle of this method consists of two parts: firstly, an approximation of the obstacles’ outline or the local horizon by a set of linear functions. Here, a survey of the...

Cost of energy and mutual shadows in a two-axis tracking PV system

Perpiñán, O. - In: Renewable Energy 43 (2012) C, pp. 331-342

The performance improvement obtained from the use of trackers in a PV system cannot be separated from the higher requirement of land due to the mutual shadows between generators. Thus, the optimal choice of distances between trackers is a compromise between productivity and land use to minimize...
