This paper deals with a mathematical model of a photovoltaic panel, which directly supplies a constant resistive load without inverter cooperation. Later on, this basic theory is used to develop a model of photovoltaic plant working with a constant resistive load. The model's correctness is evaluated through the comparison of simulated values and real measured data.
The integration of photovoltaic systems (PV) on distribution feeders may result in unfavorable increases in the number of operations of voltage regulation devices, or may decrease the effectiveness of their settings, resulting in the need for mitigation. Voltage regulation devices commonly use controllers that have time delay settings and sample power system parameters at a high frequency. Quasi-static...
In this paper, an improved two diode model of photovoltaic module is simulated using MATLAB/ Simulink. Only four parameters(Voc, Isc, Vm, Im) are required to simulate the model. Accuracy of the model is validated by testing various modules of different types (Multi Crystalline, Mono Crystalline and Thin Film). The proposed model is found to be accurate when subjected to variation in temperature and...
A new simulation model of photovoltaic module is presented in this paper, which is based on double-exponential equation. The proposed model accepts irradiance and temperature as variable parameters, can exactly simulate the current-voltage (I/V) characteristic of photovoltaic module. And a MatlabTM program for the model is also designed. The program is more accurate and need less initial input values...
The number of electronic applications using artificial neural network-based (ANN) solutions has increased considerably in the last few years. However, the ANN- application in photovoltaic systems is very limited. This paper introduces the preliminary result of the modeling and simulation of photovoltaic panel based on ANN and VHDL-language. In fact, an experimental database of meteorological data...
