Table 1 Overview of the model parameters. The parameters for the BESS and the CHP plant have been normalized individually. Thermal consumption, the hot water tank capacity, and losses have been divided by 6 in order to scale them to a size appropriate for the normalized CHP plant

From: State-based load profile generation for modeling energetic flexibility
