Low carbon economic dispatch for multi-energy distribution network with compressed air energy storage system as energy hub

Nowadays, energy crisis and environmental pollution have made utilize multiple energy in an integrated way a trend of future energy system development. The multi-energy distribution network connected via energy hubs is one of the promising solutions. In this paper, an energy hub model of compressed air energy storage system is established for the integration in the multi-energy distribution network. Aiming at reducing the whole operation and carbon cost, a low carbon economic dispatch model for multi-energy distribution network is constructed and verified on a coupled system with a 13-bus power distribution network and a 13-node district heating network, which successfully demonstrated the effectiveness of the proposed model in terms of reducing the total cost. This model can be generally extended to more complicated multi-energy networks.
