Abstract
This paper acts as a second part for stand-alone photovoltaic power system simulation to be used on site for distributed generation (DG) applications. It proposes a PV module when coupled to a load through DC-DC Converter to supply this resistive load with the maximum power from the PV module. Then some of DC-DC converters topologies are discussed in brief with concentration on Cúk and SEPIC Converters operations. After that, the mechanism of load matching is described to give the required converter duty cycle at maximum power point (MPP). Relations in 3D figures are introduced for the most probable situations for irradiance and temperature with the corresponding PV voltage and current. Also, 3D figures for the desired duty cycle, output voltage and current of DC-DC converter to gain the maximum power to the resistive load at various irradiance and temperature values. Finally, Artificial Neural Network (ANN) is used to implement a neural model with its algebraic function to take the probable irradiance and temperature values and outs the proposed converter duty cycle to give maximum power for the load. This is done with suitable number of layers, number of neurons for each and suitable performance goals.
