In the context of low-carbon economy, in order to improve the flexibility of direct energy supply to large users and deal with the asymmetric behavior decision-making of multi-agents jointly building and sharing under limited rationality, an evolutionary behavior analysis method of new energy station joint investment in low-carbon integrated microgrid hydrogen energy storage is proposed. First, based on the space-time complementarity between power generation by multiple new energy stations and energy consumption by large users, the basic framework of multi subjects sharing low-carbon integrated microgrid hydrogen energy storage is proposed, which makes each generation entity construct “self-imbalance+direct power supply+surplus grid purchase” mode. This is to decrease their investment cost while strengthening new energy friendly grid-connected capacity and power supply and consumption flexibility. Second, considering the asymmetric behavior decision-making of multiple entities in participating co-building and sharing, an evolutionary behavior analysis of multiple investment strategies for multiple new energy stations under bounded rationality based on replicator dynamic equations and an evolutionary stability theorem is conducted. Finally, the new energy gathering area in Northwest China is taken as an example and the cooperative behavior of generation side in joint investment is inferred. The results indicate that the government can incentivize joint investment behavior by providing appropriate subsidies to stations with intermittent power generation characteristics or refining electricity price settings. In this way it promotes the large-scale development of hydrogen energy storage. New energy stations can ensure their own fixed value benefits by increasing their installed capacity.
