This paper proposes a planning technique aimed at optimally sizing and locating distributed storage devices in an unbalanced low voltage microgrid. The planning procedure is formulated in terms of a mixed, non linear, constrained optimization problem: the objective function to be minimized is the cost sustained for the energy provision and for the inclusion of the storage resources while the equality/inequality constraints guarantee the correct operation of the components and of the grid. The problem of unbalances is also dealt with by imposing a maximum unbalance factor value to all of the grid busbars’ voltage. The results of numerical applications are shown to validate the proposal.

The problem of unbalances is also dealt with by imposing a maximum unbalance factor value to all of the grid busbars’ voltage.
