Abstract-The increasing demand of electricity results in a necessary expansion of the energy matrix through alternative sources, including consumers small power generators in low or medium voltage. In this microgrid scenario, one of the challenges is the automation of network communication between different devices, such as generator controllers, smart meters, etc., in order to facilitate the required exchange of information and enable networked control. Therefore, this paper presents a preliminary simulation of a distributed generator (DG) remotely controlled via a wireless communication with parameter variations. The electrical system was implemented using PLECS blockset, while the wireless network was designed using the TrueTime toolbox. In this smart microgrid application, the use of a ZigBee network to control the active power generation of the DG is evaluated under different network parameters such as loss probability and distance between the devices. Simulation results including the network occupancy allows the estimation of how many devices (or DGs) could be supported by the proposed networked solution. The results of some important variables show that the use of TrueTime toolbox enabled the modeling of wireless network in the same environment in which the control of the DG and network were modeled.
