Abstract

A Micro-Grid (MG) is interconnected with different types of energy resources such as photovoltaic, wind energy, biomass, small hydroelectric generator and fossil fuel and so on. In order to have proper coordination among these resources within microgrid requires good communication to meet the load demands. Therefore, a wireless data communication system for future microgrids is presented in this paper. It is assumed that each MG has a central controller and each Distributed Generation (DG)unit in the MG has a local controller. The communication system is responsible for transmitting and receiving data amongst these controllers. This communication system is based on Zigbee technology, which is a low cost and low power consumption device. An IOT module is included to update the information related to the electrical parameters of DG. Approaching the IOT, protocols used for data communication from the central controller to DG are MQTT and HTTP. Among these two protocols which one transfers the fluctuated data within less time from the central controller to DG in-order to stabilize the load is observed.
