How long is the cooperation period for energy storage power stations? Energy storage power stations generally have a cooperation period that depends on multiple factors, including regulatory frameworks, contractual obligations, economic viability, and technological advancements. From grid stabilization to renewable integration, strategic alliances are becoming the backbone of modern energy infrastructure. . ork for energy storage and prosumers is proposed. A bi-level energy trading model considering the network constraints is presented. A profit-sharing mechanism is d signed with the asymmetric Nash bargaining model. This study proposes a shared energy storage strategy for renewable energy station clusters to address fossil fuel dependence and support the green energy. . Shared energy storage embodies sharing economy principles within the storage industry. This approach allows storage facilities to monetize unused capacity by offering it to users, generating additional revenue for providers, and supporting renewable energy prosumers' growth.
