Abstract:
This paper presents the design, deployment and operation of an isolated smart grid in Xanthi, Greece. The overall topology and the architecture of the grid is analyzed, including the power production, transmission, consumption and the communication infrastructure. The grid consists of three smaller microgrids that are connected together through a common DC bus. Each microgrid consists of equipment exploiting various renewable energy sources, a local load, a battery and a diesel generator. In the third microgrid, hydrogen is also utilised by a long term energy storage facility. A case study shows that when the three microgrids are connected allowing energy exchange among them, the overall efficiency is greatly increased as the usage of the diesel generators is reduced and the available energy is fully exploited.
