Resumen
Electric Microgrid is a small power
generation plant composed of sources
connected in parallel to supply electrical
power in the loads can also be used as
wind turbines, photovoltaic panels,
among others as diesel machines, in the
following document analyzes the
behavior of the system with
disturbances, which are directly the
primary variables such as voltage and
frequency, in order to obtain the most
efficient control a proportional-integral
controller is implemented to observe its
response in steady state and transient,
excitation system to maintain the voltage
values in the terminals and the angle of
inclination method to stabilize the
frequency, to analyze the results of a
non-controlled micro-network, second
with control and reference gain K, third
with proposed control and modified K
and fourth with intentionally caused
disturbances such as the increase and
decrease of the load, disconnection of power lines and variation of the wind speed that enters the blades of the wind turbine. The results of this behavior show a satisfactory change, by modifying the K gain of the controller it is possible to reduce the rise and stabilization times which for the voltage and frequency variables are the most important.
