Optimal Scheduling of DC Microgrid Groups Considering Battery Storage Spatiotemporal Sharing

To address the issue of low energy utilization in microgrid energy storage, this paper proposes an optimal scheduling strategy for DC microgrid groups based on battery spatiotemporal sharing. First, by analyzing the coordination relationship between the truck and battery, their spatiotemporal transfer model is developed. On this basis, an energy sharing model of the battery which considers the special load safety guarantee requirement is established. Moreover, an optimal energy scheduling strategy of the DC microgrid group which considers the power balance constraint is designed to minimize the total system cost. Finally, numerical simulation is carried out. simulation results validate the effectiveness of the proposed strategy.
