“…Cavalcanti, Oliveira, Azeredo, Neves [1] highlighted that the Perturbation and Observation technique could not able to perform in a better manner when the solar irradiance varies more often and much quicker with respect to time. Hence the results obtained from the P&O method is not good enough in case of quick changes in temperature and irradiance.…”

A Building Integrated Photovoltaic Systems (BIPV) consists of PV modules which are integrated in to the Buildings as facades, roofs, windows, etc., The Photovoltaic PVs are mainly implemented to convert the solar irradiance in to electrical energy. These building integrated PVs are placed in different orientations and angles. However, due to the variation of the solar irradiance, temperature and also due to mismatch of electrical parameters the performances of the BIPV systems are getting affected. Also Power configurations are becomes difficult, which leads to reduced reliability and energy efficiency. Hence, this paper intends to introduce high efficient DC-DC converter by implementing a novel enemy to friend optimization algorithm technique with the use of MPPT. Initially, the solar irradiance obtained by the solar panel is converted into DC by using the Maximum Power Point Tracking (MPPT). In which, the Pulse Width Modulation (PWM) is generated based on the optimization process, for this purpose, an E2F algorithm is implemented. In this technique, the enemy who has the minimum anger (i.e. the duty cycle which has the minimum value) is selected and then make it as a friend. The output power obtained after implementing the DC-DC converter is given as the input for inverter. Finally the output of the inverter is connected to Grid or Load. In simulation, the efficiency of the proposed power module with DC – DC converter is evaluated and analyzed using the measure of those outputs with varying temperature.

“…As mentioned before a linear model for the PV array is needed for the analysis that will be shown on the buckconverter in the following sections. Since the PV array is forced to operate at the MPP when grid-connected to extract the maximum instantaneous power [3] .The I-V curve can be linearized at this point. (3) The linear model is described by the tangent to the I-V curve at the MPP point [2], [3].…”

PV applications regularly require the control of the input voltage of DC-DC converters. Unlike conventional converter, in this study the input voltage is controlled and the output voltage is maintained constant. A linearized photovoltaic (PV) array model and buck converter with constant output voltage model were used in this paper to get the transfer function of the electronic converter and to design a voltage compensator to regulate the input voltage of the converter. Results were obtained and illustrated verifying the efficiency of the compensator used in enhancing the time-response performance of the buck-based PV system by reducing the overshoot , settling and rising time. Nonetheless, enhancing the stability of the buck-based PV system.

Resumo-Este artigo apresenta um modelo matemático preciso de arranjo fotovoltaico que se integra facilmente a simuladores comuns da área de Eletrônica de Potência. Simulado em conjunto com conversores chaveados, permite avaliar o impacto de variações na temperatura e na radiação solar sobre a eficiência do sistema. Apresenta-se o procedimento para se ajustar o comportamento do modelo ao obtido com módulos comerciais. Resultados de simulação de uma fonte de corrente controlada por tensão, sensível às condições atmosféricas, revelaram uma característica I-V idêntica a do módulo KC200GT da Kyocera, cujos dados de catálogo foram utilizados. Esta proposta não segue a tendência de simplificar o circuito elétrico equivalente da célula fotovoltaica, uma vez que a perda de precisão é inevitável mediante tal circunstância. Mesmo assim, foi possível obter um modelo computacional de fácil e rápida implementação. Palavras-Chave-modelo computacional do arranjo fotovoltaico, simulação, radiação solar, temperatura.
