Abstract

The increasing needs of control, security and generation capacity of microgrids, has raised the complexity of the network and have allowed the evolution of architecture as a cluster. This increase in complexity demands control strategies in real-time, to ensure the proper functioning of the electrical system. In this research, a new communication strategy based on OFDM technology is proposed for power sharing in a microgrid cluster. To this, two modulation technologies are used based on OFDM (QPSK and 64-QAM) and the results are compared. The communication channel has been designed according to the properties of dispersion, attenuation, and noise, which are found in the applied environment. The study is based on a simulation model implemented in MATLAB, where was possible to verify the correct performance of the converters when the communications system sends the reference, achieving an error below 1%.
