  1. Interestingly, heuristic 1 without any function modeled performs quite well regarding revenue, however by taking into account relatively high violations in the control. Vice versa, bounding the SoC with heuristic 2, provides poor performance while being quite robust in provoking not many violations. Given its effort, heuristic 5 does not perform well. A reason could be the mixed-integer problem, which was not always solved to optimality
