Solar Cell performances as a power plant do not only convert energy, so that electricity is generated, but in the study of power systems it becomes a major element that has an important role in the study of power systems. As a power system element, the Solar Cell acts as an element of electricity generation in this study modelled as a PV system and connected to the network, so it must meet the requirements of the electric power network operation. Through MATLAB / SIMULINK modelling and simulations, a 100 kW peak Solar Cell power plant has been modelled to connect to the network. From the simulation and analysis obtained, this Solar Cell model shows that the connected load affects the voltage condition but does not affect the frequency. The load power factor also affects the network, namely with a lower load power factor, it affects the voltage on the network.
