ABSTRACT=The continuous advancement of the dual carbon goal will lead to fundamental changes in China's energy structure, with renewable energy emerging as the dominant force in the power supply system. As the proportion of installed capacity for renewable energy continues to grow, the absorption capacity and reasonable utilization rate of renewable energy will become a concern of all sectors of society. At present, the degree of utilization of renewable energy has emerged as a significant factor limiting the development of renewable energy sources. Due to variations in power structure, load characteristics, and flexible adjustment resources across different regions, blindly pursuing full absorption or higher utilization of renewable energy as a goal can result in escalating reserve costs for the system, limited economic benefits and hinder the development of renewable energy. Therefore, the present study develops a generation-grid-load-storage collaborative planning model aimed at achieving economic optimization, by setting different renewable energy utilization rates obtain the installed capacity of renewable energy and storage under different conditions in the planned year of Gansu province. The economic analysis indicates that the optimal utilization rate of renewable energy in Gansu Province is projected to decline from 100% during the period of 2024-2028 to approximately 90% from 2040 to 2060. It serves as a valuable tool for informing the planning and economic development of renewable energy and storage initiatives in Gansu Province, facilitating the achievement of its dual-carbon objectives.
