In this paper, the authors have done a processing of experimental data for the generated output power of two photovoltaic parks by means of different methods. An approximation of the data is done for the output power during a good day (with maximum solar radiation) by a Sum of Sinusoidal Functions, and during a bad day (small solar radiation) by a sum of Gaussian functions. The paper presents a...

The use of the combination of photovoltaic energy source and the wind energy source as a hybrid configuration has become an alternative solution to produce power energy to fed industrial and domestic applications. In order to fully exploit the energy provided by both sources and ensure a very high efficiency it is necessary to oblige the hybrid power system to produce the maximum possible power...

This paper focuses on the comprehensive modeling, simulation and experimental validation for a photovoltaic system formed by monocrystalline solar modules. The performance of the equivalent circuit model for a solar cell is validated by data measured parameters of photovoltaic modules. Also, this paper brings a novel iterative procedure to find the value of diode ideality factor, series and equ...

Photovoltaic emulators (PVE) are power electronic systems able to reproduce the output "CurrentVoltage" characteristics of photovoltaic panels in various operating conditions. They are indispensable for the design and evaluation of the operational components of a photovoltaic energy system, such as battery chargers and Maximum Power Point Tracking (MPPT). Those emulators prevent the experimenta...

One of the most important obstacles in the deployment of the clean technologies such as photovoltaic modules in the distribution system is their indefinite future in the coming years after the installation due to their intermittent nature in power generation because of the dependency to solar radiance profile. The authors in this study aim to analyze the economic, technical and environmental ef...
