Sumario: Electric power systems have to convey electricity at synchronized frequency and voltage in order to be reliable. Voltage control systems can use different strategies to achieve voltage regulation - reactive power compensation being one of them. On the other hand,
frequency control is traditionally obtained by regulation of large scale synchronous machines operations. However, the increasing use of alternative energy sources and the operation of these generators in parallel with the traditional power systems emphasize the importance
of studying the integration of these generation units. An aspect to be analyzed is the impact in the reduction of the system total inertia, that might increase frequency and voltage variations, affecting the power system stability when facing different types of disturbance. In this context, this work is dedicated to discuss the use of the concept of
additional virtual inertia, WHERE each generation unit behaves as a virtual synchronous generator, in comparison with the traditional PQ technique for power control of interface inverters. Simulation results show the virtual generator contribution to the stability of a known system, the IEEE-14 Bus.
