During the IntegrCiTy project, a novel urban energy planning approach was successfully tested. The latter combines stakeholder engagement with an innovative multi-energy model using different control strategies, while combining both energy demand and supply dynamics on selected zones. The applied control strategies applied to the energy networks show the potential gains linked to using synergies among networks and technologies, as to foster renewable energy penetration in the system. Thanks to the combined approach of advanced optimization techniques and stakeholder engagement, solutions can be identified much quicker. In addition, unfeasible solutions can be discarded at earlier stages of the planning process, based on the feedback of the stakeholders even though, from a pure mathematical and energy point of view, the solutions might be theoretically interesting to consider.
