A Novel Approach to describe and aggregate Multi-Energy Flexibility in Cellular Energy Systems using Affine Arithmetic

Flexibilities in Energy Systems are required to integrate renewable energy sources such as Photovoltaic and Wind Power. Cellular Energy Systems are discussed as a method to integrate and manage flexibilities such as Electrical Vehicles, Batteries and Controllable Loads on different levels of the Energy System. However, it is lacking a holistic flexibility model when extending the approach to Multi-Energy Systems (Electrical and Thermal Storages, Heat Pumps, CHPs, Fuel Cells, Electrolyzers etc.). This paper presents a flexibility model based on Affine Arithmetic which specifies allowed power and energy ranges while considering relations between time steps and energy forms.
