Resumen
Photovoltaic generation systems take a
strong inclusion in distribution networks,
their clean energy and adaptability, attract
a lot of interest, despite the fact that the
electronic components of these systems
are sources of poor quality voltage.
The document presents the stages prior
to the inverter, these correspond to:
behavior of photovoltaic generation,
operation of photovoltaic panels in (MPP)
by means of the (P&O) algorithm,
supplying a suitable voltage and current
ripple to the inverter by the converter,
once establishes the previous stages , the
smart inverter is able to deliver active
power, and through the control strategy
applies in the smart inverter, it allows
(deliver / absorb) reactive power and
maintain a quality supply voltage.
There is a deficient behavior when not
applying the control against the different
loads (Inductive / Capacitive), and a
noticeable difference when applying the
control (Volt-Var), in which the voltage
quality problem takes solution.
In addition, the frequency of the system
shows oscillations very close to the ideal
reference with a deviation peak to the load
change and the harmonic distortion of the
system is ideal.
