Table 1 Comparison of different optimization algorithms to minimize the energy costs over one week (06/15/18–06/21/18) for four different storage capacities. Purchasing exactly the required amount of energy in each time step, i.e., without using an electrical storage, costs 13,532 €. Note that the LP solutions are only given as lower bounds and do not correspond to feasible controls
