Resumen:
A study on the influence of the insertion of photovoltaic distributed generation in
power distribution systems is presented. The aim is to evaluate the suitability of the
most usual photovoltaic generator models in the literature to the requirements
needed in the studies of the electric power distribution systems. For this,
mathematical models corresponding to photovoltaic sources, with irradiance and
temperature curves as inputs, were programmed in MATLAB® software. From the
equations that characterize the equivalent electrical circuit of each model, the
software provides the respective characteristic curves P-V and I-V. Three models of
photovoltaic sources were evaluated under different environmental conditions of
irradiance and temperature. With the results obtained, a comparative analysis of the
accuracy of the models in the maximum power point was made. The power values
obtained by each model were applied to the modeling of a photovoltaic generator in
a test feeder built in OpenDSS software. After insertion of the solar photovoltaic
generator, the voltage profile, the technical losses and the load flow of the substation
of the system were evaluated. In general, the results showed that the solar generator
connection helped to reduce the technical losses and caused an improvement in the
voltage profile.
