Design and Implementation of AC Microgrid for AC loads

Résumé

As per the history point of view, AC power network has been the standard decision for
commercial energy to control the radiant lights in our residence and motors in our processing
plants since the late of nineteenth century. To this point, the AC control systems have existed for
over one century back alongside the AC loads ruled in the market. AC microgrid system for AC
loads is proposed which controls and monitors the power generation, distribution installed in the
building. The system electronically controls and monitors the renewable resources and variable
loads simultaneously with the microcontroller. The designed system includes solar panels and
wind turbine energy sources and also K.E energy source. The solar panel directly links to the
specially designed hybrid charge regulator in order to charge the battery as well as supply power
to the load. Similarly, the wind turbine is also directly connected to the hybrid charge controller
in order to charge a battery and supply the power to the load when there is no other source. The
K.E backup makes energy from the available grid inside the building and also connected to the
charger controller to have provision for charging from solar, wind and K.E sources. The
microcontroller used to protects the power network from the outages and faults due to low
voltage and overvoltage.
