IntegrCiTy

IntegrCiTy is an ERA-NET European project involving researchers and industrial partners from Sweden, Switzerland and Austria.

The main overall objective is to develop and implement a modular decision-support platform focusing on planning and designing integrated energy networks through multi-energy/networks co-simulation. Three pilot cases are under investigation: Hammarby Sjöstad (Stockholm, Sweden), Geneva (Switzerland) and Vevey (Switzerland).

Background

Nowadays, energy supply networks in cities – natural gas, electricity and heating/cooling - are almost always planned and operated separately from each other. The main issues to be faced are related, on one hand, to resources and needs spatial disparity and, on the other hand, to non-simultaneous demand and production. The impact will be even larger due to the increasing number of decentralized (mostly non-dispatchable) production systems and the foreseen changes in consumers’ behavior. The challenge and a part of the solution lie in the combination of storage and multi-energy conversion systems. This combination allows energy systems to adapt to an increasingly decentralized energy production, interacting with existing networks (natural gas, electricity, heating and cooling). These “smart integrated solutions” for energy management and conversion increase interoperability capabilities between different energy vectors, and open opportunities to develop additional, innovative services to the one based on existing infrastructures and related supply structures.

Aim and objectives

1. Developing an integrated decision-support environment for city planners and energy providers to improve efficiency and resilience of energy supply infrastructures, focusing on deployment, extension and retrofitting;

2. Implementing the decision-support platform and embedded tools in selected cities, for local utilities and city administrations, focusing on thermal and electrical networks linked to low-carbon resources

Outcomes

IntegrCiTy project aims at developing and implementing a modular decision-support platform focusing on planning and designing integrated energy networks and further infrastructure developments (extensions, new deployments, retrofitting) through multi-energy/networks cosimulation. The project is organized along two parallel and interdependent axes:

  • Axe I - Decision-support platform development
    • Develop the appropriate IT and data structure/management
    • Characterize the urban system at both energy demand and supply infrastructure levels by adapting existing or developing simulation models
    • Develop decision-support environment based on scenarios
    • Co-simulation process
  • Axe II - Implementation test-cases in collaboration with local authorities and utilities
    • Vevey (Switzerland)
    • Geneva (Switzerland)
    • Hammarby Sjöstad (Stockholm, Sweden)
