Welcome to the Cellular Energy System Model.

Background: The Cellular Energy System Model (CESM) is an energy system model that can be used to investigate the extent to which small-scale organizational structures ("energy cells") can be used to efficiently operate future energy systems with sector coupling and many decentralized systems. It was developed in the ZellNetz2050 research project and is currently being used and further developed in the SysZell and MOPPL projects to investigate questions of reserve provision and sector coupling.

Objective: The CESM simulates the system operation of a multisectoral energy system. The focus so far has been on a target system in the year 2045+. The electricity, heat and hydrogen requirements and the interactions between the sectors are addressed. Due to the implementation of different grid levels, the model makes it possible to analyze the interaction of transmission and distribution grids. Five distribution grids are integrated in the model's data set. The model is formulated as a linear mathematical optimization model. It is implemented in the form of rolling planning in order to obtain more realistic results for storage management. An improved management of storage facilities is currently being implemented on the basis of type weeks. In contrast to the current zonal market design in Europe, the model takes local scarcity prices into account. This allows the economic implications of structural bottlenecks and incentive structures for local flexible plants to be addressed.
