We consider the operation of coupled microgrids. Each microgrid consists of a number of residential energy systems, each including an energy storage device. The goal is to determine an optimal energy exchange between the microgrids, which results in a two-level optimization problem. On the lower level, within each microgrid, a grid operator sets up an optimization scheme to coordinate the individual subsystems. We propose a surrogate model based on radial basis functions to approximate this optimization based process and investigate its applicability in the higher level by conducting a case study based on an Australian data set.
