the power supply of remote sites and applications at minimal cost and with low emissions is an important issue when discussing future energy concepts. this paper presents modeling and optimization of a photovoltaic (pv)/wind/diesel system with batteries storage for electrification to an off-grid remote area located in rafsanjan, iran. for this location, different hybrid systems are studied and ...

Arising applications of ferroelectric materials in photovoltaic devices" The ferroelectric-photovoltaic (FE-PV) device, in which a homogeneous ferroelectric material is used as a light absorbing layer, has been investigated during the past several decades with numerous ferroelectric oxides. The FE-PV effect is distinctly different from the typical photovoltaic (PV) effect in semiconductor p–n j...

In this paper, a simulation study of the maximum power point tracking (MPPT) for a photovoltaic system using an artificial neural network is presented. Maximum power point tracking (MPPT) plays an important role in photovoltaic systems because it maximizes the power output from a PV solar system for all temperature and irradiation conditions, and therefore maximizes the power efficiency. Since ...

Reconfigurable photovoltaic (PV) systems are of great interest with respect to system designers in order to improve the system’s efficiency and operation. This paper proposes an adaptive reconfiguration scheme to reduce the effect of shadows on solar panels. A method to capture the maximum power point of the photovoltaic (PV) array systemwith the help of DC/DC central converter system is presen...

The photovoltaic (PV) systems exhibits nonlinear I-V characteristics and maximum power point varies with solar radiation or insolation and temperature. An intermediate pulse width modulation dc to dc converters can increase efficiency of the system by providing impedance matching between the PV system and the load and operating the PV cell arrays at their maximum power point using MPPT techniqu...

The market for photovoltaic (PV) energy systems is expanding rapidly in the U.S. Almost 100,000 PV systems have been installed in California alone, more than 90% of which are residential. Some of those “PV homes” have sold, yet little research exists estimating if those homes sold for significantly more than similar non-PV homes. A clearer understanding of these effects might influence the deci...

A circuit based model of photovoltaic array (PV) suitable for simulation studies of solar power systems is proposed in this paper. The proposed model is realised using Power System Block Set under MATLAB/SIMULINK, however, it can be constructed using standard simulation software such as PSPICE. The proposed circuit model has several advantages: simple, reliable, allows simulation of basic cells...

We describe the development of new, Web-based maps of insolation and photovoltaic energy potential across Canada. The maps will be made available on the Natural Resources Canada website. They are presented for each month and summed for the entire year, for five different surface orientations: a suntracking orientation and four fixed South-facing orientations with latitude, vertical and latitude...

When large capacity distributed generation including photovoltaic (PV) systems are installed in power systems, reverse power flow from PV systems may cause problem of surplus electric power. To reduce the reverse power flow without the reduction of PV power generation, energy management of customer equipment such as electric water heater is one of the solutions. Therefore, cooperative control o...
