Sustainable Restoration Strategy for Optimal Dispatch of Integrated Energy Systems for Urban Areas

This paper studies the urban regional integrated energy system (IES) considering the coupling of electricity, gas and thermal energy. Based on the optimal scheduling of integrated energy, the energy storage equipment is pre-charged before the disaster, aiming to improve the sustainable recovery capacity of the IES. The coupled operation constraint model of the electricity, gas and thermal integrated energy system has been constructed, and the electric-thermal load recovery power and the electric-thermal energy storage state are used as decision variables to establish the objective function of maximizing the load weighted recovery power and energy storage disaster preparedness level. Finally, the improved IEEE 33-bus distribution network, 14-node natural gas network (NGN) and 6-node thermal grid are used as a simulation case, and the entire optimal dispatch of integrated energy systems (ODIES) model is solved by GUROBI to verify the effectiveness of the proposed sustainable restoration strategy.
