Electricity consumption accounts for a high proportion in the total energy consumption of domestic industrial parks. In response to green and low-carbon development initiative of industrial parks, an electric power and energy rebalancing method for new power systems at the receiving ends of industrial parks is proposed. Firstly, electric power and energy demands are forecasted, and their initial balances are struck. Then, taking the coordination of source-grid-load-storage ends of a distribution network， and the energy conservation, electricity substitution, various distributed power sources, energy storage and demand response capability of industrial parks into consideration, electric power and energy are rebalanced. The proportions of electricity purchased from external power grid and electricity generated in the industrial park are annually adjusted according to the rebalancing results. Then, an evaluation system with quantitative indicators including carbon reduction effect and the size of power systems is established， which can evaluate the reduction effect on substation and distribution capacities and carbon emissions brought by electric power and energy rebalance. Finally, the proposed method is validated by a case of a new power system in an industrial park in southern China. The results indicate that: by 2030, the designed substation and distribution capacity of this park can be reduced by 10.1%, and the comprehensive carbon emission factor of electricity consumption can be reduced from 0.60 kg/（kW·h） to 0.54 kg/（kW·h）; by 2060, the designed substation and distribution capacity can be reduced by 9.57%, and electricity substitution will reduce the carbon emissions by 58 500 t per year. The rebalance method provides a strong theoretical support for the planning of new power systems at receiving ends.
