Under the “dual carbon” goal

the new-type power system is characterized by the coordinated development of generation

grid

load

and storage

constituting a complex and systematic project.To scientifically forecast the investment scales of multiple agents

this paper develops a system dynamics-based prediction model and conducts a simulation analysis using the Ningxia region as a case study.The results show that the investment scales and evolution trends of generation

grid

and energy storage differ significantly under various development scenarios

highlighting the significant impacts of economic growth rate

power transmission capacity

and renewable energy penetration on investment demand.The findings can provide a valuable reference for investment planning and decision-making of relevant stakeholders in new-type power systems.
