In the solutions we obtained, the battery is used quite frequently and, thanks to that, large savings can be obtained. However, the battery may in fact be used only once a day or even not used at all, depending on the grid activity. Hence, taking into account only a limited number of uses is a key factor to be considered in future research.
The value of the time discretization (Delta ) has also an impact on the total amount of savings, since a better battery management policy can be obtained by a finer discretization of the time horizon.
