The web-of-cells concept, or cellular concept, is an approach to mitigate the challenges arising from the transformation of energy systems, both from a technical as well as an economic perspective. The manifestation of this approach presented in this paper incorporates all system levels and takes the existing energy infrastructure into account, thus, it differs from low-level approaches focused on increasing autonomy as well as from green-field conceptual studies. The main principle remains unchanged from previous work: the energy system is divided into energy cells based on the extent of the energy infrastructure on each system level. These cells are ordered strictly hierarchically, limiting the direct technological and economic interaction mostly to vertically adjacent energy cells. A vertically complete market concept tailored to this decomposed energy system follows the web-of-cells idea by aggregating and disaggregating information on an intermediate level between end-users and the central market. Additionally, market and grid operation are no longer being viewed as separate, but rather as complementary tasks. Local marginal pricing is introduced to steer actors’ behaviours by providing economic incentives according to the grid congestion situation. To prove this system and market concept, an extensive and detailed simulation is being created. First results show that the system and market concept is suitable to match variable supply and energy demand and that local marginal pricing behaves as expected.
