In order to improve the level of clean energy utilization and the operation efficiency of the power system, the power supply scale and energy storage capacity configuration of the integrated park project are solved. Based on the historical data on the electricity load in the park, this paper analyzes the characteristics of the monthly and daily electricity load. An integrated mathematical model with operating cost and new energy consumption as the optimization goal and multiple energy operation characteristics as the constraints is proposed to realize the optimization of the comprehensive planning of source-grid-load-storage in the region. Taking an electrolytic aluminium project as a case study, the overall curtailment rate of new energy in the optimized scheme is 3.56%, and the proportion of electricity consumed by new energy is 51.19% of the overall electricity consumption of the project.
