In this research a three phase photovoltaic
Energy System connected to the grid with three types of
control, proportional plus integral control, sliding mode
control and artificial neural network control were
controlling the PV grid connected Energy system. The
proposed controllers are affected by the current dynamic
response for the system. The performance of the developed
artificial neural network control and sliding mode control
were compared with a conventional proportional plus
integral control. The simulated results had proved that the
output current and power in advanced control (artificial
neural network control) and Adaptive control (sliding
mode control) were better than classic control
(proportional plus integral control).
