Figure 5From: Determining cost-efficient controls of electrical energy storages using dynamic programmingOptimizing a number of days at once rather than in sequence improves the result. In this example, the costs for optimizing both days separately sum up to 6796 € , jointly to 6752 €, assuming a constant energy consumption of 200 kWh. The horizontal red and black lines represent the bounds on the capacity and the purchased energy, respectivelyBack to article page
